Title: Microorganisms Inhabiting Mushroom Compost during Fermentation
Author: M. Stanek
Abstract:
The results of research show the importance of microorganisms in mushroom
growing in a steadily increasing way.
It is to be seen that in mushroom growing
the mixed culture of mycelium of Agaricus bisporus (Lange) Singer, as well as
specific microorganisms are applied, which form a community-microbial
association - of partners influencing each other (Hayes, et al., 1969; Stanėk,
et al., 1971, etc.).
Especially important are microorganisms that
- (a) form during the preparation of the compost a suitable nutrient medium for
the mushroom,
- (b) accompany the mycelium of Agaricus bisporus in the nutrient medium and
influence its growth,
- (c) inhabit the casing layer and influence the formation of mushroom fruit
bodies and their healthy condition.
Microorganisms colonizing the mushroom compost during the course of
fermentation, i.e. during composting of organic materials in piles and during the
so-called pasteurization, can be regarded as active factors in the preparation of
the mushroom nutrient medium - they fashion the chemical composition of
the compost, change its physical properties and make the growth of the
competitive microorganisms more difficult.
Their studies are supplemented and
made more accurate by the research into transformations of organic matter
occurring during composting (Waksman, Allen, 1932; Waksman, Nissen, 1932;
Waksman, et al., 1939; Burrow, 1951; Bretsloff & Fleugel, 1962; Delmas &
Dureau, 1962; Gerrits, et al., 1967, etc.). The practical aim of this study is to
find out the most suitable condition for the correct fermentation process and to
obtain a bacterial preparation intended for the inoculation of the compost in the
case of some modern methods of the preparation of compost for mushroom
growing (Huhnke, Sengbusch, 1969; Huhnke, 1970) and for growing other fungi.
