The moderately halophilic bacterium Nesterenkonia sp. strain F, which was isolated from Aran-Bidgol Lake (Iran), has the ability to produce acetone, butanol, and ethanol (ABE) as well as acetic and butyric acids under aerobic and anaerobic conditions. This result is the first report of ABE production with a wild microorganism from a family other than Clostridia and also the first halophilic spe...

A marine photosynthetic bacterium (PS88) identified as Rhodovulum sp. with flocculating ability was isolated from the sea sediment mud of a shrimp cultivation farm in Thailand. This bacterium flocculated in glutamate/malate medium during aerobic/dark or anaerobic/light cultivation. The flocculating ability was enhanced with the increase of NaCl concentration to 6% (w/v). Flocculation and growth...

The Gram-negative bacterium Klebsiella planticola represents an interesting host organism for the production of biotechnological products. Microbial processes – especially those of aerobic cultivation – lead to the generation of considerable amounts of biomass, thus lowering the product yield. These are the reasons for studying methods for the recycling of biomass from K. planticola. It will be...

The yeast Saccharomyces cerevisiae is unique among eukaryotes in exhibiting fast growth in both the presence and the complete absence of oxygen. Genome-wide transcriptional adaptation to aerobiosis and anaerobiosis was studied in assays using DNA microarrays. This technique was combined with chemostat cultivation, which allows controlled variation of a single growth parameter under defined cond...

The occurrence and system of detection of mesophilic and psychrotrophic aerobic sporulating microorganisms (MPAS) in raw cow’s milk were studied. Samples of raw cow’s milk from bulk tanks were collected 21 times from 14 farms during one year. MPAS assessment is based on inactivation of milk sample at the temperature of 80–82°C for 30 minutes followed by incubation in cultivation dishes at 30±1°...

In this work, corrections are made to the descriptions of the species Anoxybacillus pushchinoensis corrig. and the genus ANOXYBACILLUS: Experiments to determine the relationship of A. pushchinoensis K1(T) to oxygen showed that it was capable of aerobic growth, but preferred to grow anaerobically. During aerobic growth, the redox indicator resazurin was reduced as a result of hydrogen gas produc...

One hundred eighty four strains belonging to the species Lactobacillus casei, L. paracasei and L. rhamnosus were screened for their ability to grow under aerobic conditions, in media containing heme and menaquinone and/or compounds generating reactive oxygen species (ROS), in order to identify respiratory and oxygen-tolerant phenotypes. Most strains were able to cope with aerobic conditions and...
