The aim of this work was to produce lipases by solid-state fermentation (SSF) using, as substrate, agroindustrial residue supplemented with by-products from corn oil refining process or olive oil. For a group of ten fungi strains selected in the first steps, the lipase activity obtained by SSF varied from 7.7 to 58.6 U/g of dry substrate (gds). Among the evaluated strains, the Aspergillus niger...

Amyloglucosidase (α-1, 4 glucan glucohydrolase EC 3.2.1.3) hydrolyses amylaceous polysaccharides, removing successive glucose units in the β configuration from the non-reducing end of the chain. Amyloglucosidase is of considerable commercial importance to grain alcohol fermentation, food, textile and pharmaceutical industry. The aim of this study is to purify and characterize amyloglucosidase P...

Xylanases activity (XY) from Aspergillus japonicus URM5620 produced by Solid-State Fermentation (SSF) of castor press cake (Ricinus communis) on different conditions of production and extraction by PEG/citrate aqueous two-phase system (ATPS) were investigated. XY production was influenced by substrate amount (5-10 g), initial moisture (15-35 %), pH (4.0-6.0) and temperature (25-35 °C), obtainin...

Culture conditions of a newly isolated basidiomycetous strain were optimized for the enhanced production of extracellular alkali-thermotolerant cellulase-poor xylanase using wheat bran as the sole carbon source under solid state fermentation (SSF). SEM and ITS sequencing confirmed it as Coprinopsis cinerea HK-1 NFCCI-2032. Among various inexpensive agro-residues, wheat bran (carbon source) came...

The production of a notable and highly effective pectinase and cellulase, by the commercial baker’s yeast Saccharomyces cervisiae utilizing potato processing wastes, was achieved in 5-day solid state fermentation (SSF) cultures, at temperature 25 °C, pH range 4.0-5.0 and additive of ferric chloride. Pectinase and cellulase activities were stimulated by using potato wastes supplemented with urea...

Polygalacturonase and α-amylase play vital role in fruit juice industry. In the present study, polygalacturonase was produced by Aspergillus awamori Nakazawa MTCC 6652 utilizing apple pomace and mosambi orange (Citrus sinensis var mosambi) peels as solid substrate whereas, α-amylase was produced from A. oryzae (IFO-30103) using wheat bran by solid state fermentation (SSF) process. These carbohy...

BACKGROUND Distiller's dried grains with solubles (DDGS) and soybean meal were used as the substrates for the production of polyunsaturated fatty acids (PUFA) in solid-state fermentation (SSF) by Mortierella alpine. These fermented products were fed to laying hens. PUFA enrichment from chicken breasts was studied. METHODS The maximum productivity of PUFA was achieved under optimized process c...

Laccases have potential applications in industrial, biotechnological, and environmental set ups. Development of cost effective and efficient production technologies has gained significant attention in recent years. To enhance the laccase production from Rheinheimera sp. (Gram negative) using submerged fermentation (SmF) and from Lysinibacillus sp. (Gram positive) using solid-state fermentation ...

Nine substrates were investigated for phytase production by Penicillium funiculosum NRC467 fine particles of crushed fava bean has been selected as the best substrate using solid state fermentation (SSF). The SSF conditions were optimized by using one-variable-at-a-time (OVAT) strategy. Penicillin G has been used to enhance phytase production instead of the traditionally used Tween 80 and Trito...
