Abstract:

The possible use of agricultural waste waters for the growth and for the metabolites production by Lentinus edodes under submerged cultural conditions was studied Particularly olive oil waste waters alone or added with malt extract 4‰ w/v been taken into consideration. The fungal biomass has been grown in liquid substrates m a rotary shaker and in a bioreactor. The growth rate was highest during the initial 14 days,during which the biomass production was correlated with the pH of the liquid growth medium During the growth and the developmemt of Lentinus edodes certain enzyme activities (laccase and peroxidase) were also tested. An important factor in fungus metabolism is the oxygen tension. Infact biomass growth proceeds rapidly when the cultures are sufficiently aereated while the enzymatic activity appears considerable higher when the cultures are greatly aereated
