"Now I would like to propose 2 themes for discussion. 1. We have a very big yeast factories in ex-USSR, yeasts were cultivated on wood hydrolysates or oil fractions. This industry gave up to 1 million tones of fodder protein per year, but this protein had a very unpleasant toxic and allergic effects. Latest research found that it was caused by wild yeast strains that did replace cultural yeasts in reactors after 2-3 months of cultivation! Thus, in truth cultural high productive yeasts couldn't be used in industrial systems because the system is not stabile. In this correlation I would like to ask Bachtar Bakrie if he had the experiments of A.niger culture using during 5-6 passes on the non-sterile substrates? Farmers can't buy a pure starter culture every week, they will use available filaments of the fungus - like it's when we make a tempeh fermentation." Thought some might be interested.
