Thermophilic fermentation of acetoin and 2,3-butanediol by a novel Geobacillus strain
UNLABELLED BACKGROUND Acetoin and 2,3-butanediol are two important biorefinery platform chemicals. They are currently fermented below 40°C using mesophilic strains, but the processes often suffer from bacterial contamination. RESULTS This work reports the isolation and identification of a novel aerobic Geobacillus strain XT15 capable of producing both of these chemicals under elevated temp...
متن کاملPurification and characterization of an acidic, thermophilic phytase from a newly isolated Geobacillus stearothermophilus strain DM12
Microbial phytases were applied mainly to animal and human foodstuffs in order to improvemineral bioavailability and food processing. In addition, phytases have potentialbiotechnological application in various other fields, such as environmental protection,aquaculture and agriculture. Bacillus sp. DM12, an isolate from a hot spring, produces phytase,which catalyzes the hydrolysis of phytic acid...
متن کاملConversion of cellulose and hemicellulose of biomass simultaneously to acetoin by thermophilic simultaneous saccharification and fermentation
BACKGROUND Acetoin (3-hydroxy-2-butanone), the precursor of biofuel 2,3-butanediol, is an important bio-based platform chemical with wide applications. Fermenting the low-cost and renewable plant biomass is undoubtedly a promising strategy for acetoin production. Isothermal simultaneous saccharification and fermentation (SSF) is regarded as an efficient method for bioconversion of lignocellulos...
متن کاملBiodesulfurization of Dibenzothiophene by a Newly Isolated Thermophilic Bacteria Strain
Microbiological analyses of soil chronically exposed to petroleum complex compounds of some oil springs in south of Iran resulted in isolation and purification of a new native thermophilic strain which is capable to desulfurize petroleum sulfur compounds by 4-S mechanism. Dibenzothiophene (DBT) was selected as a complex sulfur compound model and many experiments were done to identify the me...
متن کاملEfficient simultaneous saccharification and fermentation of inulin to 2,3-butanediol by thermophilic Bacillus licheniformis ATCC 14580.
2,3-Butanediol (2,3-BD) is an important starting material for the manufacture of bulk chemicals. For efficient and large-scale production of 2,3-BD through fermentation, low-cost substrates are required. One such substrate, inulin, is a polydisperse fructan found in a wide variety of plants. In this study, a levanase with high inulinase activity and high pH and temperature stability was identif...
