Abstract

Process for ensiling green fodder using bacterial preparations of lactic acid-producing bacteria, in which Lactobacillus plantarum DSM 3676 and/or Lactobacillus plantarum DSM 3677 is used.

Description

The invention relates to a process for acidifying green fodder by using bacterial preparations of lactic acid-producing bacteria.
Silage making from green fodder has enormous economic 5 importance, and various processes and additives have been proposed for accelerating the fermentation of green fodder batches or for improving silage making. These include the addition of lactic acid-producing bacteria, because the fermentation of lactic acid is an essential process in silage making from green fodder.
At the end of fermentation, a good silage should contain about 2 to 3% lactic acid by weight. The bacteria added should be able to ferment all or as much as possible of the sugar contained in the green fodder. But this aim has not been adequately achieved by the known bacteria which have previously been added to silage (cf OE~A 252 040).
« The problem which the present invention seeks to solve, therefore, is to provide bacterial preparations or bacteria which yield improved silage, or which in particular effect a stronger acidification in a quicker time, while substantially avoiding a butyric acid fermentation. - 3 The invention accordingly provides a process for the acidification of green fodder using bacterial preparations of lactic acid-producing bacteria, which is characterized by the use of Lactobacillus plantarum DSM 3675 and/or t ι Lactobacillus plantarum DSM 3677.
It has surprisingly been found that the two microorganisms DSM 3676 and DSM 3677, when used together, have a synergistic action. It is therefore preferred to use a mixture of 10 to 90% Lactobacillus plantarum DSM 3675 and 90 to 10% Lactobaci11 us plantarum DSM 3677, referred to the A mixture of 30 to 70% DSM 3676 especially 40 to 60% DSM 3676 and particularly preferred. number of cells present and 70 to 30% DSM 3677, 60% to 40% DSM 3577, is The invention relates also to the use of Lactobacillus plantarum DSM 3676 and/or Lactobacillus plantarum DSM 3677 for the ensiling of green fodder.
The two microorganisms mentioned above, used in accordance with the invention, have not been described heretofore.
One of these microorganisms was originally labelled by the applicant with the designation B5 and deposited on 12 March 1986 in the German collection of microorganisms, Grisebachstr 8, D-3400 Goettingen, and received the deposit number DSM 3676. (Deposit according to the Budapest Treaty on the internetional recognition of deposits of microorganisms for the purposes of patent procedures).
The second microorganism was originally labelled by the applicant with the designation W2 and likewise deposited on , 12 March 1986 at the same depository. It was accorded the deposit number DSM 3677. » Both microorgan isms were identified as Lactobaci11 us plantarum, subspecies arabinosus. They exhibit the following properties: . 4 no gas formation DL - lactic acid no ammonia from arginine optimum temperature c 35C no growth at 45’C growth at 15"C cell wall component: diami nopimo1inic acid sugar fermentation g1ucose mannitol g1 veer i n arab i nose sucrose pos i t ive positive negative pos i t ive pos i t ive 15 1actose positive mel1ibiose positive dextrin positive ( in the case of W2) (weaker in the case of B5) starch negat i ve 20 esculin (? illegible) pos itive maltose positive melicitose positive xylose negative ribose positive 25 t r i h a 1 o s e pos it ive raffinose positive sorbitol positive salicinose pos i t i ve rhamnose positive (in the case of W2) 30 (negative in the case of B5) Differences: W2 forms mucus B5 forms no mucus - 5 Acetate tolerance: 1.5% for W2 0.5% for B5 Morphology/: W2 = single rods B5 = short rods in chains Acidification in MRS pH 3.81 for B5 pH 3.79 for W2 Metabolism determined for B5: 2 mol lactate are formed from one mol glucose, 1 mol lactate plus 0.65 mol acetate and traces of ethanol are formed from 1 mol dripose.
The microorganisms can be cultivated in conventional manner. Suitable culture conditions in MRS medium: pH before sterilization: 6.9 steri1ization 20 minutes at 121’C pH after steri1ization : 6.6 behaviour towards oxygen: microaerophi1ic (1) On preservative agar with refrigerator storage.
Incubation temperature: 25 to 32°C Duration of incubation: 24 hours Sub-cultivation interval: about 3 months.
Suitable storage conditions: a) master culture in preservative agar (conventional for Lactobacilli). After initial growth, storage in / refrigerator. b) Freeze-dried culture has almost unlimited storage life * at -20’C.
Conditions for viability testing: Poured plate or master culture in MRS-media.
The new microorganisms are characterized by special capabilities in the intensity and speed of fermentation of sugars, such as are present in green fodder, at normal silage temperatures.
The microorganisms were isolated from green fodder silage in the early phase of fermentation.
The following tables describe the results achieved during acidification of grass or lucerne using the microorgan isms according to the invention, and silage media of the present state of the art. The lower the pH value, the stronger is the acidification achieved, and the better are the results for the s i1 age.
The following abbreviations are used in the tables: TS: dry substance Kofa-Lac (registered trade mark): commercial state-of-theart preparation Kofa-Plus: commercial state-of-the-art preparation based on chemicals 5 5 The numbers 10 or 10 represent the numbers of cells per 1 ml or 1 g of the fresh batch (inoculation strength). Unster: unsterile Biomax (registered trade mark): commercial state-of-theart preparation The figures given in the tables are the respective pH values.

If necessary a substance having an alkaline reaction can be added to the nutrient medium during cultivation, in order to prevent the pH value from dropping too low. Examples of such alkaline substances are potassium hydroxide solution, sodium hydroxide solution, soda solution. The separation of the cells can be carried out in conventional manner. For example the cells can be separated in a centrifuge. A protective substance, for example a protective colloid, eg powdered milk can then be added to them. Other protective substances can also be used, for example lactose, ascorbic acid.
The cells can then be freeze-dried. A stable preparation is obtained, which contains the active bacteria and can be stored for a long time without losing its activity.
The preparation can be added to the silage mix in known manner by hand, or by the use of metering devices, powder sprays and the like.
US-A-4 528 199 and AT-A-262 040 describe use of Lactobacillus plantarum preparations for ensiling green xodder. As compared with the preparations described therein, the bacteria used according to the invention have unexpectedly improved properties with regard to the speed of ensiling.
