Solid-state fermentation conditions were investigated for cellulase production by marine Aspergillus ZJUBE-1 using crop straw as the main material. When Aspergillus ZJUBE-1 was grown under the condition: ratio of rice straw to wheat bran was 1:1, the ratio of material to liquid was 1:2, the ratio of nitrogen and carbon was 5.6%, NaCl was 2.4~4.0%, temperature at 37 °C, the maximum CMCase activi...

BACKGROUND A solid-state anaerobic digestion method is used to produce biogas from various solid wastes in China but the efficiency of methane production requires constant improvement. The diversity and abundance of relevant microorganisms play important roles in methanogenesis of biomass. The next-generation high-throughput pyrosequencing platform (Roche/454 GS FLX Titanium) provides a powerfu...

Two-phase olive-mill waste, the so-called "ecological", has been treated with a Paecilomyces variotii isolate in solid state fermentation experiments. The growth of the microorganism was estimated by measuring the production of carbon dioxide, using gas chromatography. A 46% increase of the protein content was achieved at the fermented product, after molasses addition at the initial mixture. Th...

The production of extracellular xylanase by a newly isolated fungus Simplicillium obclavatum MTCC 9604 was studied in solid-state and submerged fermentation. Multiple xylanases and endoglucanases were produced by the strain during growth on wheat bran in solid state fermentation (SSF). A single xylanase isoform was found to be produced by the same fungus under submerged fermentation (SF) using ...

BACKGROUND Although lovastatin production has been reported for different microorganism species, there is limited information about lovastatin production by basidiomycetes. AIMS The optimization of culture parameters that enhances lovastatin production by Omphalotus olearius OBCC 2002 was investigated, using statistically based experimental designs under solid state fermentation. METHODS Th...

Demand for microbial amylase production persists because of its immense importance in wide spectrum industries. The present work has been initiated with a goal of optimization of solid state fermentation condition for amylase using agroindustrial waste and microbial strain like B. amyloliquefaciens (MTCC 1270). In an aim to improve the productivity of amylase, fermentation has been carried out ...

The production of cellulase-free xylanase was investigated with a locally isolated and identified strain, Cellulosimicrobium sp. MTCC 10645 in solid state fermentation. Different fermentation conditions were standardised for the growth and xylanase activity, the optimum being 72 h growth at pH 7.0, cultivation temperature 40°C and substrate to moisture ratio of 1:1.8 (w/v). Among different lign...

ABSTRACT In recent times, green technologies have gained space and interest in many industrial sectors. Examples of this are enzymes, which can be obtained by solid-state fermentation using microorganisms agro-industrial residues as substrates. context, study aimed to verify the production hydrolases leading Arthrobacter polychromogenes Streptomyces violaceoruber strains producers influence moi...

Among enzymes, lipases have been widely investigated because of the numerous industrial applications. In this study, optimization of lipase production by Aspergillus niger in solid state fermentation from rice bran as solid substrate was investigated. The optimal conditions with the aid of central composite design (CCD) under response surface methodology (RSM) were obtained.  In the analysis of...
