Crude enzymes produced via solid state fermentation (SSF) using wheat milling by-products have been employed for both fermentation media production using flour-rich waste (FRW) streams and lysis of Rhodosporidium toruloides yeast cells. Filter sterilization of crude hydrolysates was more beneficial than heat sterilization regarding yeast growth and microbial oil production. The initial carbon t...

The genus Arthrospira comprises a group of filamentous multicellular cyanobacteria and can be used for animal feed and human food. Solid state fermentation or cultivation (SSF) involves the use of a culture medium composed of solid material with given moisture content. No studies have been published about the cultivation of microalgae or cyanobacteria on solid medium. Furthermore, although suga...

Cellulase production studies have been carried out using the fungal strain Trichoderma reesei NCIM 992 by using three different lignocellulosic materials by solid state fermentation (SSF). The effect of basic fermentation parameters (pH, temperature, moisture content, particle size of substrate and moistening agent) on enzyme production was studied. Maximum cellulase production was 2.63 U ml(-1...

Penicillium spp. are known to harbor a wide array of secondary metabolites with cryptic bioactivities. However, the metabolomics of these species is not well-understood in terms of different fermentation models and conditions. The present study involved metabolomics profiling and transcriptomic analysis of Penicillium expansum 40815 under solid-state fermentation (SSF) and submerged fermentatio...

In order to assure the consistency of the final product quality, a fast and effective process monitoring is a growing need in solid state fermentation (SSF) industry. This work investigated the potential of non-invasive techniques combined with the chemometrics method, to monitor time-related changes that occur during SSF process of feed protein. Four fermentation trials conducted were monitore...

Gibberellic acid (GA3) is an important phytohormone, a member of gibberellins family, which acts as a promoter and regulator of plant growth. This study aimed to evaluate GA3 production by Fusarium moniliforme LPB03 and Gibberella fujikuroi LPB06 using different techniques of fermentation, solid state fermentation (SSF), submerged fermentation (SmF), and semisolid state fermentation (SSSF), and...

Solid state fermentation (SSF) has been practiced for centuries in the Orient and Asian region in both large and small scale applications in food processing and production of traditional fermented foods. Products such as fermented soybean (tempe, soy sauce, annatto, miso, etc) and fermented rice (tapai, koji, red fermented rice, brewing of the Japanese rice wine (sake)) among others are based o...

This study investigates the production of crude Ca-independent and low pH active α-amylase by Bacillussp. KR-8104 in submerged fermentation (SmF) and solid-state fermentation (SSF) systems. Differentparameters were evaluated in each system using “one factor at a time” approach to improve the production ofenzyme. The results showed that in the SmF the maximum enzyme production ...

The Japanese fermented food Natto contains menaquinone 7 (MK7), which is known to increase bone mineral density and reduce bone fractures. Natto is traditionally produced via the solid state fermentation of soy beans by Bacillus subtilis natto. The aim of this study was to investigate the effects of static and dynamic solid state fermentation (SSF) on the production of MK7 using polenta (milled...

The lignocellulosic biomass (especially agricultural wastes) is known to be an excellent carbon source for microbial enzyme production. In this paper, the cellulase production from lignocellulosic materials under solid state fermentation (SSF) was investigated. The effects of fermentation conditions, such as moisture content, initial pH, temperature, and composition of mixed substrate (wheat st...
