25. DETERMINATION OF ZINC BACITRACIN BY DIFFUSION IN AN AGAR MEDIUM

1.

PURPOSE AND SCOPE

The method is for the determination of zinc bacitracin in feedingstuffs, concentrates and premixes. The lower limit of determination is 5 mg/kg (5 ppm). (a). The method is not valid in the presence of interfering substances, particularly large amounts of copper and ascorbic acid.

2.

PRINCIPLE

The sample is extracted at pH 2 with a mixture of methanol/water/hydrochloric acid. The extract is brought to pH 6.5, concentrated (where necessary) and diluted. Its antibiotic activity is determined by measuring the diffusion of zinc bacitracin in an agar medium inoculated with Micrococcus luteus (Syn. M. flavus). Diffusion is shown by the formation of zones of inhibition of the micro-organism. The diameter of these zones is taken to be in direct proportion to the logarithm of the antibiotic concentration over the range of antibiotic concentrations employed.

(

a

) 1 mg feed grade zinc bacitracin is equivalent to 42 international units (i.u.).

3.

MICRO-ORGANISM: MICROCOCCUS LUTEUS AT CC 10240 (NCTC 7743)

3.1

Maintenance of stock culture

Inoculate Micrococcus luteus on to agar slopes of culture medium (4.1). Incubate for 24 hours at 30 to 37°C, store in a refrigerator at about 4°C and reinoculate every two weeks on to agar slopes.

3.2

Preparation of the bacterial suspension (a)

Harvest the growth from a recently prepared agar slope (3.1) with 2 to 3 m1 of sodium chloride solution (4.3). Use this suspension to inoculate 250 m1 of culture medium (4.1) contained in a Roux flask and incubate for 18 to 20 hours at 30 to 37°C. Harvest the growth in 25 m1 of sodium chloride solution (4.3) and mix. Dilute the suspension to one-tenth with sodium chloride solution (4.3). The light transmission of the suspension must be about 75% measured at 650 nm in a 1 cm cell against sodium chloride solution (4.3).

7.

Assay Procedure

7.1

Inoculation of the assay medium

Inoculate the assay medium (4.2) with the bacterial suspension (3.2) at about 50°C. By preliminary trials on plates with assay medium (4.2) determine the quantity of bacterial suspension required to give the largest and clearest zones of inhibition with the various concentrations of zinc bacitracin.

7.2

Preparation of the plates

Diffusion through agar is carried out in plates with concentrations of the standard solution (S

8

, S

4

, S

2

, S

1

) and the four concentrations of the assay solution (U

8

, U

4

, U

2

, U

1

). These four concentrations of extract and standard must necessarily be placed on each plate. To this effect select plates big enough to allow at least eight holes with a diameter of 10 to 13 mm and not less than 30 mm between centres to be made in the agar medium. The test may be carried out on plates consisting of a sheet of glass with a faced aluminium or plastic ring placed on top, 200 mm in diameter and 20 mm high.

Pour into the plates a quantity of the medium (4.2), inoculated as in point 7.1, to give a layer about 2 mm thick (50 ml for a plate of 200 mm diameter). Allow to set in a level position, bore the holes and place in them exactly measured volumes of assay and standard solutions (between 0.10 and 0.15 ml per hole, according to the diameter).

Apply each concentration at least four times so that each determination is subject to an evaluation of 32 zones of inhibition.

7.3

Incubation

Incubate the plates for 16 to 18 hours at 28 to 30°C.

8.

Evalation

Measure the diameter of the zones of inhibition to the nearest 0.1 mm. Record the mean measurements for each concentration on semi-logarithmic graph paper showing the logarithm of the concentrations in relation to the diameters of the zones of inhibition. Plot the 'best fit' lines of both the standard solution and the extract, for example as below.

Determine the 'best fit' point for the standard lowest level (SL) using the formula

Determine the 'best fit' point for the standard highest level (SH) using the formula

Similarly calculate the 'best fit' points for extract lowest level (UL) and the extract highest level (UH) by substituting U

1

, U

2

, U

4

and U

8

for S

1

, S

2

, S

4

and S

8

in the above formulae.

Record the calculated SL and SH values on the same graph paper and join them to give the 'best fit' line for the standard solution. Similarly record UL and UH and join them to give the 'best fit' line for the extract.

In the absence of any interference the lines should be parallel. For practical purposes the lines can be considered parallel if the values (SH-SL) and (UH-UL) do not differ by more than 10% from their mean value.

If the lines are found to be non-parallel, either U

1,

and S

1

or U

8

and S

8

may be discarded and SL, SH, UL and UH calculated, using the alternative formulae, to give alternative 'best fit' lines

and similarly for UL and UH. The alternative 'best fit' lines should be checked for parallelism as before. The fact that the result has been calculated from three levels should be noted on the final report.

When the lines are considered as being parallel, calculate the logarithm of the relative activity (log A) by means of one of the following formulae.

For four levels

For three levels

or

Real activity = supposed activity x relative activity.

When the lines are considered as not being parallel, repeat the determination. If parallelism is still not achieved, calculate the logarithm of the relative activity (log A) by means of formula (c). The result obtained must however be considered as approximate and this should be noted in the final report.

9.

Repeatability

The difference between the results of two determinations carried out on the same sample by the same analyst should not exceed

20% of the higher result for contents of zinc bacitracin equal to or greater than 5 but not greater than 25 mg/kg;

5 mg/kg, in absolute value, for contents greater than 25 but not greater than 50 mg/kg;

10% of the higher result value for contents greater than 50 mg/kg.

26. DETERMINATION OF FLAVOPHOSPHOLIPOL BY DIFFUSION IN AN AGAR MEDIUM.

1.

Purpose and Scope

The method is for the determination of flavophospholipol in feedingstuffs, concentrates and premixes. The lower limit of determination is 1 mg/kg (1ppm).

2.

Principle

The sample is extracted with diluted methanol by heating under reflux. After centrifuging, the extract is purified (where necessary) by treatment with ion exchange resins and diluted. Its antibiotic activity is determined by measuring the diffusion of flavophospholipol in an agar medium inoculated with Staphylococcus aureus. Diffusion is shown by the formation of zones of inhibition of the micro-organism. The diameter of these zones is taken to be in direct proportion to the logarithm of the antibiotic concentration over the range of antibiotic concentrations employed.

27. DETERMINATION OF THE TRACE ELEMENTS IRON, COPPER, MANGANESE AND ZINC

1.

Purpose and scope

The method is for the determination of the trace elements iron, copper, manganese and zinc in feedingstuffs. The lower limits of determination are:—

iron (Fe)

20mg/kg

copper (Cu)

10mg/kg

manganese (Mn)

20mg/kg

zinc (Zn)

20 mg/kg

2.

Principle

The sample, or the residue resulting from ashing, if there is organic matter present, is treated with hydrochloric acid. The elements iron, copper, manganese and zinc are determined, after appropriate dilution, by atomic absorption spectrometry.

3.

Reagents

Introductory comments

For preparation of the reagents and analytical solutions use water free from the cations to be determined, obtained either by double distilling water in a borosilicate glass or quartz still or by double treatment on ion exchange resin.

The reagents must be of at least analytical grade. Freedom from the element to be determined must be checked in a blank experiment. If necessary, the reagents must be further purified.

In determining trace elements it is important to be alert to the risks of contamination, particularly by zinc, copper and iron. For this reason, the equipment used in preparing the samples must be free of these metals.

To reduce the general risk of contamination, work in a dust-free atmosphere with scrupulously clean equipment and carefully washed glassware. The determination of zinc is particularly sensitive to many types of contamination e.g. from glassware, reagents, dust, etc.

In place of the standard solutions described below, commercial standard solutions may be used provided that they are guaranteed and have been checked before use.

Ashing and preparation of the solution for analysis

(

*

)

.

(*) Green fodder (fresh or dried) is liable to contain large amounts of vegetable silica, which may retain trace elements and must be removed. For samples of these feedingstuffs, therefore, the following modified procedure must be followed.

Carry out operation 5.1.1. (I) as far as the filtration. Wash the filter paper containing the insoluble residue twice with boiling water and place it in a platinum crucible (4.3). Ignite in the muffle furnace (4.1) at a temperature below 550°C until all carbonaceous material has completely disappeared. Allow to cool, add a few drops of water followed by 10 to 15 ml of hydrofluoric acid (3.4) and evaporate to dryness at about 150°C. If any silica remains in the residue, redissolve it in a few millilitres of hydrofluoric acid (3.4) and evaporate to dryness. Add five drops of sulphuric acid (3.5) and heat until no more white fumes are given off. After the addition of 5 ml of 6 N hydrochloric acid (3.2) and about 30 ml of water, heat, filter the solution into the 250 ml volumetric flask and make up to the mark with water (HC l concentration about 0.5 N). Proceed then with the determination from point 5.1.3.

(I) Place 5 to 10 g of sample weighed to the nearest 0.2 mg in a quartz or platinum crucible (4.3) (see Note (a)), dry in an oven at 105°C and introduce the crucible into the cold muffle furnace (4.1). Close the furnace (see Note (b)) and gradually raise the temperature to 450 to 475°C over about 90 minutes. Maintain this temperature for 4 to 16 hours (e.g. overnight) to remove carbonaceous material and then open the furnace and allow to cool (see Note (c)).

Wash the crucible out with a total of about 5 ml of hydrochloric acid (3.1) and add the latter slowly and carefully to the beaker (there may be a vigorous reaction due to CO

2

formation). Add hydrochloric acid (3.1) dropwise with agitation until all effervescence has stopped. Evaporate to dryness, occasionally stirring with a glass rod.

Next add 15 ml of 6 N hydrochloric acid (3.2) to the residue followed by about 120 ml of water. Stir with the glass rod, which should be left in the beaker, and cover the beaker with a watchglass. Bring gently to the boil and maintain at boiling point until no more ash can be seen to dissolve. Filter on ash-free filter paper and collect the filtrate in a 250 ml volumetric flask. Wash the beaker and filter with 5 ml of hot 6 N hydrochloric acid (3.2) and twice with boiling water. Fill the volumetric flask up to the mark with water (HC l concentration about 0.5N).

(II) If the residue in the filter appears black (carbon), put it back in the furnace and ash again at 450 to 475°C. This ashing, which only requires a few hours (about three to five hours), is complete when the ash appears white or nearly white. Dissolve the residue with about 2 ml of hydrochloric acid (3.1), evaporate to dryness and add 5 ml of 6 N hydrochloric acid (3.2). Heat, filter the solution into the volumetric flask and make up to the mark with water (HC l concentration about 0.5 N).

Notes

(

a

) The weight of sample to be ashed is calculated from the approximate trace element content of the feedingstuff in relation to the sensitivity of the spectrophotometer used. For certain feedingstuffs low in trace elements it may be necessary to start with a 10 to 20 g sample and make up the final solution to only 100 ml.

(

b

) Ashing must be carried out in a closed furnace without injection of air or oxygen.

(

c

) The temperature indicated by the pyrometer must not exceed 475°C.

5.1.2

Spectrophotometric determination

5.1.2.1

Preparation of calibration solutions

For each of the elements to be determined, prepare from the working standard solutions given in points 3.7.1., 3.8.1., 3.9.1. and 3.10.1. a range of calibration solutions, each calibration solution having a HC l concentration of about 0.5 N and (in the cases of iron, manganese and zinc) a lanthanum chloride concentration equivalent to 0.1% La /w/v). The trace element concentrations selected must lie within the range of sensitivity of the spectrophotometer used. The tables below show, by way of example, the compositions of typical ranges of calibration solutions; depending, however, on the type and sensitivity of spectrophotometer used it may be necessary to select other concentrations.

Proparation of solution for analysis

For the determination of copper, the solution prepared from point 5.1.1. can normally be used directly. If necessary to bring its concentration within the range of the calibration solutions, an aliquot portion may be pipetted into a 100 ml. volumetric flask and made up to the mark with 0.5 N hydrochloric acid (3.3).

For the determination of iron, manganese and zinc, pipette an aliquot portion off the solution prepared from point 5.1.1 into a 100 ml volumetric flask, add 10 ml of lanthanum chloride solution (3.11) and make up to the mark with 0.5 N hydrochloric acid (3.3) (see also point 8 'Observation').

5.1.2.3

Blank experiment

The blank experiment must include all the prescribed steps of the procedure except that the sample material is omitted.

The calibration solution 'O' must not be used as the blank.

5.1.2.4

Measurement of the atomic absorption

Measure the atomic absorption of the calibration solutions and of the solution to be analysed using an oxidising air-acetylene flame at the following wavelengths.

Fe

248.3 nm

Cu

324.8 nm

Mn

279.5 nm

Zn

Carry out each measurement four times.

5.2

Mineral Feedingstuffs

If the sample contains no organic matter, prior ashing is unnecessary. Proceed as described in point 5.1.1 ( I ) starting from the second paragraph. Evaporation with hydrofluoric acid may be omitted.

6.

CALCULATION OF RESULTS

Using a calibration curve, calculate the trace element concentration in the solution to be analysed and expressed the result in milligrams of trace element per kilogram of sample (ppm).

7.

REPEATABILITY

The difference between the results of two parallel determinations carried out on the same sample by the same analyst should not exceed

— 5 mg/kg, in absolute value, for contents of the trace element concerned not greater than 50 mg/kg;

— 10% of the higher result for contents of the trace element concerned greater than 50 but not greater than 100 mg/kg;

— 10 mg/kg, in absolute value, for contents of the trace element concerned greater than 100 but not greater than 200 mg/kg;

— 5% of the higher result for contents of the trace element concerned greater than 200 mg/kg.

8.

OBSERVATION

The presence of large quantities of phosphates may interfere with the determination of iron, manganese and zinc. Such interference must be corrected by addition of lanthanum chloride solution (3.11). If, however, in the sample the weight ratio

is greater than 2, addition of lanthanum chloride solution (3.11) to the solution for analysis and to the calibration solutions may be omitted".
