Homofermentative against yeasts
After extensive research scientists have concluded that a biological silage additive should contain homofermentative lactic acid bacteria to achieve the best results, as these bacteria are able to convert sugar 2 to 6 times more efficiently than heterofermentative bacteria.
However, high quality silages with a high sugar content are also more prone to heating after opening. When air enters the silo, yeasts start wasting sugar, thus causing a rise in pH and temperature. These visible losses are universally acknowledged on farms. However, even in silos that have not been opened yet, sugar is wasted by yeasts. These losses that can be used, however, generally remain unnoticed.
Anaerobic fermentation of fructose and glucose
by homo- and heterofermentative lactic acid bacteria

1. Homofermentative lactic acid bacteria
(e. g. Lactobacillus plantarum, Pediococcus pentosaceus)
- 1 glucose (or 1 fructose) ⇒ 2 lactic acid
Efficiency: 100%
2. Heterofermentative lactic acid bacteria
(e. g. Lactobacillus buchneri resp. brevis)
- 1 glucose ⇒ 1 lactic acid + 1 ethanol + 1 CO2
Efficiency: 50%
- 3 fructose ⇒ 1 lactic acid + 2 mannitol + 1 acetic acid + 1 CO2
Efficiency: 16,7%

Chr. Hansen has been looking for a solution to this problem. The following yeasts were determined to be mainly responsible for heating after opening and DM losses in silages:
- Pichia fermentans
- Candida krusei (Dr. Muck)
- Candida krusei (ATCC)
- Pichia anomala
- Rhodotorula mucilaginosa
 |
After more then 5 years of research and development and after having tested more than 100 strains of bacteria, two homofermentative Lactobacillus plantarum-strains were selected for Biomax® 5. These strains inhibit the above-mentioned yeasts during fermentation, storage and after opening. |
Biomax® 5 is the perfect choice for whole plant and maize silages between 20 % and 70% DM that are rich in carbohydrates.
