Abstract
The influence of environmental parameters on mycelial linear growth ofPleurotus ostreatus, P. eryngii, P. pulmonarius, Agrocybe aegerita, Lentinula edodes, Volvariella volvacea andAuricularia auricula-judae was determined in two different nutrient media in a wide range of temperature, forming the basis for the assessment of their temperature optimaV. volvacea grew faster at 35°C,P. eryngii at 25°C,P. ostreatus andP. pulmonarius at 30°C,A. aegerita at 25 or 30°C andA. auricula-judae at 20 or 25°C depending on the nutrient medium used andL. edodes at 20 or 30°C depending on the strain examined. The mycelium extension rates were evaluated on seven mushroom cultivation substrates: wheat straw, cotton gin-trash, peanut shells, poplar sawdust, oak sawdust, corn cobs and olive press-cake. The mycelium extension rates (linear growth and colonization rates) were determined by the ‘race-tube’ technique, and were found to be the highest on cotton gin-trash, peanut shells and poplar sawdust forPleurotus spp. andA. aegerita. Wheat straw, peanut shells and particularly cotton gin-trash supported fast growth ofV. volvacea, whereas wheat straw was the most suitable substrate forL. edodes andA. auricula-judae. Supplemented oak sawdust and olive press-cake were poor substrates for most species examined, white almost all strains performed adequately on corn cobs.
