We investigated butanol production from crystalline cellulose by cocultured cellulolytic Clostridium thermocellum and the butanol-producing strain, Clostridium saccharoperbutylacetonicum (strain N1-4). Butanol was produced from Avicel cellulose after it was incubated with C. thermocellum for at least 24 h at 60°C before the addition of strain N1-4. Butanol produced by strain N1-4 on 4% Avicel c...

background and objectives: microbial spoilage of juices and industries related with alicyclobacillus are considerable international issues. this spore-forming bacterium causes changes in juices odor and taste. the isolation and identification of alicyclobacillus contamination in juice producing and packaging industries has an essential role in the prevention and control of this type of spoilage...

probiotics, living microorganisms which when used in adequate amounts, have health benefits on the host, have attracted a considerable deal of interest in the biotechnology market. various prokaryotic and eukaryotic microbes have been studied for probiotic purposes in human and animals. lactobacillus and bifidobacterium are the main probiotic genera; however, there are reports on the probiotic p...

A Cr(VI)-resistant, Gram-positive, spore-forming, obligate anaerobe, designated GCAF-1(T), was isolated from chromium-contaminated soil by its ability to reduce Cr(VI) in low concentrations. Mixed acid fermentation during growth on glucose resulted in accumulation of acetate, butyrate, formate and lactate. Morphological studies indicated the presence of peritrichous flagella, pili and an S-laye...

A Gram-negative, oxidase-positive, catalase-negative, facultatively anaerobic, motile, curved rod-shaped bacterium, strain N384(T), was isolated from a marine sponge (Scleritoderma cyanea; phylum Porifera) collected from a depth of 795 feet (242 m) off the west coast of Curaçao. On the basis of 16S rRNA gene sequencing, strain N384(T) was shown to belong to the genus Vibrio, most closely relate...

Laboratory aquarium experiments demonstrated that Vibrio strain AK-1 caused rapid and extensive bleaching of the coral Oculina patagonica at 29 degrees C, slower and less-complete bleaching at 23 degrees C, and no bleaching at 16 degrees C. At 29 degrees C, the application of approximately 100 Vibrio strain AK-1 cells directly onto the coral caused 50 and 83% bleaching after 10 and 20 days, res...

Anaeromyxobacter dehalogenans strain 2CP-C is a versaphilic delta-Proteobacterium distributed throughout many diverse soil and sediment environments. 16S rRNA gene phylogenetic analysis groups A. dehalogenans together with the myxobacteria, which have distinguishing characteristics including strictly aerobic metabolism, sporulation, fruiting body formation, and surface motility. Analysis of the...

A fluorene-degrading strain named USTB-C was isolated from crude oil of production well in Dagang oil field, southeast of Tianjin, northeast China. The 16S rDNA sequence of USTB-C showed 100% similarity with that of Rhodococcus erythropolis PR4, it was belonged to Rhodococcus. The strain USTB-C could remove 55.8% of fluorene with an initial concentration of 100 mg L in 23 days without other sub...

Sixty-six clinical isolates of Candida albicans representing 14 different strain types were tested for their phospholipase and proteinase activities in correlation with adherence to buccal epithelial cells (BECs) and lethality to mice. Variations in phospholipase and proteinase production as well as adherence to BECs were observed both among isolates of the same strain type and between isolates...
