Lentinus edodes (L. edodes) is one of the most famous traditional Chinese medicines and high producer of various bioactive compounds such as polysaccharides. Modern pharmaceutical research shows that the Polysaccharides (LEPLS) of this mushroom is a kind of bioactive compound with clinical significance in medicine and several physiological effects. Up to now, fermentation system has been widely...

BACKGROUND Simultaneous saccharification and fermentation (SSF) is a promising process option for ethanol production from lignocellulosic materials. However, both the overall ethanol yield and the final ethanol concentration in the fermentation broth must be high. Hence, almost complete conversion of both hexoses and pentoses must be achieved in SSF at a high solid content. A principal difficul...

Nine aerobic cellulolytic bacterial cultures were obtained from the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Culture (DSMZ) and the American Type Culture Collection (ATCC). The objectives of this study were to characterize the cellulolytic bacteria and to determine the optimum moisture ratio required for solid state fermentation (SSF) of palm kernel cake (PKC). The ba...

The production of extracellular amylase by Bacillus subtilis has been studied in solid-state fermentation (SSF). In a sequential order, various process parameters were optimized for maximum amylase production. The tested process parameters were different solid substrates such as banana husk (BH), water melon husk (WMH), lentil bran (LB), wheat bran (WB), melon husk (MH) and maize oil cake (MOC)...

This paper reports the production of ligninase enzymes by a new strain of Trametes versicolor IBL-04 producing a novel pattern of ligninolytic enzymes with highest MnP activities followed by LiP and laccase. In previous studies Trametes versicolor has been reported to produce higher activities of MnP, followed by laccase and LiP. Lignocellulosic substrates including wheat straw, rice straw, ban...

Microbial enzymes during solid-state fermentation (SSF), which play important roles in the food, chemical, pharmaceutical and environmental fields, remain relatively unknown. In this work, the microbial communities and enzymes in SSF of Pu-erh tea, a well-known traditional Chinese tea, were investigated by integrated metagenomics/metaproteomics approach. The dominant bacteria and fungi were ide...

The current study optimized the production of α-amylase by Bacillus subtilis using solid state fermentation (SSF) process. The agricultural by-product of rice straw was utilized as a substrate support for the fermentation process. The characterization of untreated and NaOH-treated rice straw was conducted using Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Analysis (EDX). The o...

A novel strain Rhizopus sp. C4 was isolated from compost for the production of pectinase. Cultivation of Rhizopus sp. C4 on orange peel substrate under various solid-state fermentation (SSF) conditions was evaluated for pectinase yield along with the enzyme activity profile as a potential, low-cost alternative to submerged-liquid fermentation. Response surface methodology (RSM) was employed to ...

The aim of this study was screening fungi strains, isolated from manipueira (a liquid subproduct obtained from the flour production of Manihot esculenta), for amylases production and investigating production of these enzymes by the strain Aspergillus 6V4. The fungi isolated from manipueira belonged to Ascomycota phylum. The strain Aspergillus 6V4 was the best amylase producer in the screening a...

Simultaneous saccharification and fermentation (SSF) is the most commonly practiced operation in lignocellulose bioconversion to avoid the sugar product inhibition to cellulase enzymes. In this study, for the first time SSF was tested on microbial lipid fermentation using the diluted acid pretreated and biodetoxified corn stover. The results show that SSF was effective than the separate hydroly...
