BACKGROUND In continuation of our previously interest in the saccharification of agriculture wastes by Bacillus megatherium in solid state fermentation (SSF), we wish to report an investigation and comparative evaluation among Trichoderma sp. for the saccharification of four alkali-pretreated agricultural residues and production of hydrolytic enzymes, carboxymethyl cellulase (CMCase), filter pa...

BACKGROUND Despite its semi-commercial status, ethanol production from lignocellulosics presents many complexities not yet fully solved. Since the pretreatment stage has been recognized as a complex and yield-determining step, it has been extensively studied. However, economic success of the production process also requires optimization of the biochemical conversion stage. This work addresses t...

Nine Aspergillus and three of Trichoderma strains were grown on wheat bran (WB) medium under solid state fermentation (SSF) for amylase production. Aspergillus oryzae LS1 produced the highest level of the enzyme. The thermal stability profile of its crude enzyme revealed the half-life time of more than 2 h at 50 and 60ºC. The enzyme production was affected by strain type, incubation periods, le...

The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...

In this study, solid-state fermentation (SSF) was proposed as an alternative approach to obtain optically pure forms of one of the most common aroma compounds, whisky lactone. Filamentous fungi were used for enantioselective hydrolysis of a racemate of trans and cis whisky lactones, utilizing rapeseed cake as a growth medium. Among the tested fungi, Fusarium oxysporum AM13 and Papularia rosea A...

Fungal strain Trichoderma spp. is a known bio control agent (BCA), which are difficult to obtain using more prevalent industrial-scale biofermentation methods such as submerged fermentation (SmF) However, up-scalable solid-state (SSF) appropriate for BCA production. An automated semi-rotating drum bioreactor was developed and built explore SSF scale-up pea wheat bran substrates valorise food-in...

This study was undertaken to isolate ligninase-producing white-rot fungi for use in the extraction of fibre from pineapple leaf agriwaste. Fifteen fungal strains were isolated from dead tree trunks and leaf litter. Ligninolytic enzymes (lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase (Lac)), were produced by solid-state fermentation (SSF) using pineapple leaves as the substrate...

Onion (Allium cepa) is a valuable vegetable and candidate for sustainable waste management in agri-food industry. The purpose of the current paper was to research utilization onion peels an economical substrate inulinase production by Yarrowia lipolytica ISF7 strain under solid state fermentation (SSF). SSF preferred obtain effective low-cost production. medium designation optimized using Taguc...

Animal fleshing, the major proteinaceous solid waste generated from leather industry, was used as substrate for the production of alkaline protease by Bacillus cereus 1173900 in solid-state fermentation (SSF). Maximum protease activity of 12,310 U/g was observed at 60 h in SSF crude extract. The extracted protease enzyme was purified by 53.64-fold through ammonium sulphate precipitation and chr...

Response surface methodology was used to evaluate optimal time, temperature and oxalic acid concentration for simultaneous saccharification and fermentation (SSF) of corncob particles by Pichia stipitis CBS 6054. Fifteen different conditions for pretreatment were examined in a 2(3) full factorial design with six axial points. Temperatures ranged from 132 to 180 degrees C, time from 10 to 90 min...
