Cyclodextrin glycosyltransferase (CGTase) catalyzes the conversion of starch into non-reducing cyclic sugars, cyclodextrins, which have several industrial applications. This study aimed to establish optimal culture conditions for β-CGTase production by Bacillus sp. SM-02, isolated from soil of cassava industries waste water lake. The optimization was performed by Central Composite Design (CCD) ...

The development of appreciable brine acidity in cucumber salt stock is necessary for curing the cucumbers and maintaining a desirable color during subsequent storage of stock. Several investigators (Le Fevre, 1920,1922; Joslyn, 1929; Fabian et al., 1932; Fellers et al., 1937; Fellers, 1939) recommended the addition of sugar to cucumber fermentations with the object of stimulating the acid formi...

Hyaluronic acid (HA) is a linear polysaccharide with high molecular weight composed of disaccharide units of D-glucuronic acid (GlcUA) and N-acetylglucosamine (GlcNAc). HA is naturally present in vertebrate organisms, as well as in bacteria. HA can be obtained commercially through three routes: human umbilical cords, rooster combs, and strains of group C Streptococcus. This is a natural polysac...

BACKGROUND Chinese Nong-flavor (NF) liquor is continuously and stably produced by solid-state fermentation technology for 1000 years, resulting in enrichment of special microbial community and enzymes system in its starter. Based on traditional culture-dependent methods, these functional enzymes are hardly obtained. According to our previous metatranscriptomic analysis, which identifies plenty ...

Spores of Clostridium bifermentans KMR-1 were produced for use as a microbial inoculum for bioremediation and were preserved in both liquid and dry forms. All spore formulations showed good viability and ability to biodegrade the target compound, 2,4,6-trinitrotoluene (TNT), after 4 months of storage. For low-cost bulk spore production, several medium compositions, based on soy peptone, corn st...
