BIO-1 Lecture Notes - Lecture 26: Lignin, Pasteurization, Industrial Waste
Document Summary
Excessive periods > 60 degrees c destroy selectivity. Optimal for growth = neutral to alkaline. Microbial biomass before spawning = 2% compost dry weight. Bacteria estimate = 1 x 1011/g dry weight. Fungal and actinomycete mycelium = 39. 5 km/g dry weight. Agaricus bisporus = enzymes to degrade bacteria and fungi. Phase 3: vegetative growth stage spawn run. Successful colonization of the phase 2 substrate by the mushroom fungus. Cereal grain colonized by fungus (wheat, rye, millet) Incorporation of microbial biomass into mushroom mycelial biomass. Carbon dioxide levels between 3 000 20 000 ppm. Compost temperature 24 27 degrees c. Formed into a continuous block of compost. Phase 4: vegetative growth stage case run. Successful colonization of the casing layer by the mushroom fungus. Large volume (1 2 l/m each time) Treat with chemicals outside, steam in open container, or steam/treat in closed container. Without this step there would be no mushroom crop.
