“…In most cases, mycelia capable of producing normal fruit bodies result from the plasmogamy of two genetically compatible haploid mycelia. Moreover, the development of fruit bodies from dikaryotic vegetative mycelia that are genetically able to fruit is influenced by various environmental factors such as light (Eger et al, 1974), temperature (Zadražil, 1974), humidity, carbon dioxide (Zadražil, 1975), and carbon/nitrogen nutrient sources. These factors act together to induce the formation of primordia and subsequent fruit bodies from the vegetative mycelia.…”

Effect of light and reductones on differentiation of Pleurotus ostreatus

et al. 2011

Vegetative mycelia of Pleurotus ostreatus were differentiated into primordia and subsequently into fruit bodies in synthetic sucrose-asparagine medium when exposed to light at low temperature. During photo-morphogenesis, L-ascorbic acid-like substances called reductones were produced. L-ascorbic acid, D-erythroascorbic acid, 5-O-(α-D-glucopyranosyl)-D-erythroascorbic acid, 5-O-(α-D-xylopyranosyl)-D-erythroascorbic acid, 5-methyl-5-O-(α-D-glucopyranosyl)-D-erythroascorbic acid and 5-methyl-5-O-(α-D-xylopyranosyl)-D-erythroascorbic acid were accumulated initially in the illuminated mycelia before the initiation of fruiting. The content of glycosides of erythroascorbic acid and their methylated compounds increased again in the primordia and the fruit bodies. Exogenous L-ascorbic acid induced the formation of primordia from the mycelia in the dark in a dose-dependent manner. Thus, this suggests that these reductones might play a role in mediating the light stimulus in photomorphogenesis.

“…Nutrition provided by the substrate is the most important factor affecting the yield of mushrooms. Zadrazil (1975) investigating the mycelial growth of Pleurotus ostreatus and Pleurotus florida reported that higher rates of mycelial growth increased the rate of penetration of the substrate by the fungi, which simplifies overall cultivation. Microbial biomass constitutes 2% of compost weight and act as a concentrated source of nitrogen and minerals for the mushroom mycelium (Wood and Smith, 1988).…”

We investigated the effect of nitrogen fixing Azotobacter bioinoculant on the mycelial growth and the rate of substrate utilization by Pleurotus eous. The synergistic or antagonistic role of the microorganism during dual culturing with the mushroom or the competitor molds Trichoderma viride, and Trichoderma reesi was studied. Azotobacter was inhibitory to the molds, which are competitive to the mushroom in the seed spawn substrate, but was synergistic towards the mushroom. The growth, substrate utilization potential as total nitrogen content and cellulase enzyme activities of the mushroom in the seed spawn substrate were also enhanced in the presence of the bioinoculant at lower inoculum concentrations, upto 5 ml broth culture per spawn bottle.

“…Most published research findings have revealed that agitated cultivation leads to the attainment of higher ligninoytic enzyme activities [45,46]. This effect could be attributed to mechanical damage to the mycelium during agitation and its harmful effect on fungal growth and synthesis of enzymes as well as to changes in CO 2 concentration in the medium [13,50]. In addition, the increase in the volume ratio of medium/air did not affect enzyme production.…”

Because of the crucial role of ligninolytic enzymes in a variety of industrial processes, the demand for a new effective producer has been constantly increasing. Furthermore, information on enzyme synthesis by autochthonous fungal strains is very seldom found. Two fungal strains producing ligninolytic enzymes were isolated from Bulgarian forest soil. They were identified as being Trametes trogii and T. hirsuta. These two strains were assessed for their enzyme activities, laccase (Lac), lignin peroxidase (LiP) and Mn‐dependent peroxidase (MnP) in culture filtrate depending on the temperature and the type of nutrient medium. T. trogii was selected as the better producer of ligninolytic enzymes. The production process was further improved by optimizing a number of parameters such as incubation time, type of cultivation, volume ratio of medium/air, inoculum size and the addition of inducers. The maximum activities of enzymes synthesized by T. trogii was detected as 11100 U/L for Lac, 2.5 U/L for LiP and 4.5 U/L for MnP after 14 days of incubation at 25°C under static conditions, volume ratio of medium/air 1:6, and 3 plugs as inoculum. Among the supplements tested, 5% glycerol increased Lac activity to a significant extent. The addition of 1% veratryl alcohol had a positive effect on MnP.
