ABSTRACT:
The strains, PS 64-103; PS 24-44; and PB 33-48 are mutation products of the perfect fungi Polyporus squamosus and Polyporus brumalis and are characterized by the fact that in a liquid nutrient medium they tend to form hiffs, colonies and secondary spores, subdividing in geometric progression with rapid growth which varies in speed, depending on the seeding material ratio in a period of from 6 to 36 hours. The nutrient medium in which the mycelium is developed is quite simple in composition and comprises three components, i.e., 4-5% of molasses; 0.2% of NH.sub.4 NO.sub.3 ; 0.12% of KH.sub.2 PO.sub.4 and 0.04% of vegetable oil as foam suppressant. The strains assimilate from 50 to 60% of a given amount of saccharoses, accumulating to 1 to 1.2% of dry biological mass.
The fungi mycelium can be adapted as a food product and is also used as an additive to various meat and other food products, i.e., sausage, minced meat, soft and smoked cheeses, vegetable canned food, soups, and bread and other bakery products. The waste water stimulates the growth of vegetables.
