“…Very low substrate concentration fails to trigger enzyme production to desirable level because most of the inoculum remains without substrate and hence resulting in minimum secretion of enzymes. Optimum substrate concentration normally results in an increase in the yield and reaction rate of the hydrolysis (Regina et al 2008). However, high substrate concentration can cause substrate inhibition, which substantially lowers enzyme production (Liu and Yang 2007;Singhania et al 2007).…”

“…Following the same pattern, holocelulose (cellulose + hemicellulose) also decreased after the second mushroom production cycle by 10.84% 21.58% and 13.90%. These polymers were hydrolyzed by enzymes produced by L. edodes as laccases, manganese peroxidase and lignin peroxidase (Regina et al, 2008), and converted into nutrients used for mushroom growth (Gomes-da-Costa et al, 2008).…”

Lentinula edodes (Shiitake) is an edible mushroom with excellent nutritional potential, aroma and flavor. It’s traditionally produced on wood logs, but this practice has been replaced by cultivation on axenic substrates (AS) made from different materials that are stored in plastic bags. This papper aimed to evaluate the nutritional composition of L. edodes grown on Quercus acutíssima (QA) and AS by correlating their chemical composition with the media on which they were grown. Culture media were analyzed for their density, moisture content, ash, extractives, lignin (soluble and insoluble) and holocelulose before L. edodes inoculation, as well as after the second consecutive harvest this mushrooms. The mushrooms from the second harvest of each culture media were characterized regarding their moisture content, protein, ash, lipids, dietary fiber (soluble and insoluble), α, β and glucanas total, carbohydrates and minerals. Mushrooms cultivated on AS showed higher protein content, macrominerals and lipids, when compared to mushrooms cultivated on QA. AS initially contained lower lignin content, less holocelulose and a reduced C:N ratio when compared to QA. The results showed that the composition of the culture medium influenced the nutritional composition of L. edodes mushrooms.

“…In SSF, microbial growth occurs on or near the surface of the solid and optimum moisture level in SSF is governed by the water holding capacity of the substrate and water requirements of the fungus (Asgher et al, 2006). Higher and lower water contents adversely affect the primary metabolic activities of microbes causing lower ligninase production in secondary growth (Rodriguez et al, 1998;Raghavarao et al, 2003;Regina et al, 2008). Low moisture contents may also result in reduced solubility of nutrients, lower substrate swelling and higher water tension (Lonsane et al, 1992).…”

The present study deals with production of ligninolytic enzymes from an indigenous white rot fungus Schizophyllum commune IBL-06 by using banana stalk as substrate through the process of solid state fermentation. The production process was further improved by optimizing a number of physical parameters such as incubation time, moisture level, pH, temperature, inoculums size and nutritional factors (carbon and nitrogen ratio, mediators and metal ions). By optimization of different parameters, the maximum activities of enzymes synthesized by S. commune IBL-06 were observed as 3745 IU/ml for manganese peroxidase (MnP), 2700 IU/ml for lignins peroxidase (LiP) and 345 IU/ml for laccase after 3 days incubation at рH 4.5 and 35°C temperature with 3 ml inoculum size, 60% moisture content, 20:1 C:N ratio (glucose and ammonium nitrate as carbon and nitrogen supplements), 1ml of 1mM MnSO 4 as mediator, and 1ml of 1mM MgSO 4 .7H 2 O 2. This High activities of ligninolytic enzymes produced by the fungus suggest its potential for commercial scale production of these enzymes for diverse industrial applications.
