TL;DR: In this paper, the feasibility of waste loquat kernels as substrate in solid-state fermentation for α-amylase production by Penicillium expansum MT-1 was investigated.
Abstract: The major aim of present study was to investigate the feasibility of waste loquat kernels as substrate in solid-state fermentation for α-amylase production by Penicillium expansum MT-1. The kernels accounted for 22.5% of whole fruit (by wet weight). They were rich in protein (22.5%) and total carbohydrate (71.2%). The starch accounted for 25.6% of total carbohydrate and 36% of whole kernel, on dry weight basis. The fungus was isolated from fermented loquat kernels. Loquat kernel flour (LKF) could serve as a sole source of nitrogen and carbon for the fungus to grow and synthesize α-amylase. However, additional carbon and nitrogen sources increased the enzyme production. Supplementation of each one of alcohols gave rise to a positive effect on the enzyme production. Optimal conditions for the production of α-amylase by the fungus on LKF were determined as initial moisture content of 70%, particle size of 1 mm, pH 6.0, incubation temperature of 30 0 C, starch and peptone as supplements, 1 ml methanol as supplement alcohol and incubation period of 6 days. Under the optimized culture conditions, the maximum enzyme production was 1012 U/g of LKF. Usability of waste loquat kernels as substrate in microbial culture media for the production of α-amylase was investigated for the first time in the present study.

TL;DR: In this article, the authors used Schyzophyllum commune and Ganoderma lucidum to produce crude ligninolytic enzymes extracts using corn stover and banana stalk as a substrate during solid state fermentation (SSF).
Abstract: There is an increasing demand for green chemistry technologies that can cope with environmental waste management challenges. Agro-industrial residues are primarily composed of complex polysaccharides that support microbial growth for the production of industrially important enzymes such as ligninolytic enzymes. Schyzophyllum commune and Ganoderma lucidum were used alone, as well as mixed/co-culture, to produce crude ligninolytic enzymes extracts using corn stover and banana stalk as a substrate during solid state fermentation (SSF). In the initial screening, the extracted ligninolytic enzymes from S. commune produced using corn stover as the substrate showed higher activities of lignin peroxidase (1007.39 U/mL), manganese peroxidase (614.23 U/mL), and laccase (97.47 U/mL) as compared to G. lucidum and the mixed culture. To improve the production of ligninolytic enzymes by S. commune with solid state fermentation (SSF), physical factors such as pH, temperature, moisture, inoculum size, and incubation time were optimized by varying them simultaneously using response surface methodology (RSM) with a central composite design (CCD). The optimum SSF conditions were (for a 5 g corn stover substrate size): pH = 4.5; temperature = 35°C; inoculum size = 4 mL; and moisture content = 60%. Under optimum conditions, the activities of lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase were 1270.40, 715.08, and 130.80 IU/mL, respectively.
