A novel strictly anaerobic, cellobiose-degrading bacterium, strain CelloT, was isolated from a human faecal sample by combining enrichments in liquid and soft-agar basal media. A noteworthy characteristic was its inability to grow on normal agar plates and in roll tubes. The cells were coccus shaped and non-motile, with an extracellular slime layer. Growth of strain CelloT occurred between 20 a...

recent technological improvements have extended the application range of dielectric permittivity biomass measurements to on-line monitoring of physiological changes during bacterial fermentations. in an industrial fermentation of bacillus thuringiensis, it is important to verify the intactness of bacterial plasmid content in all steps of culture. changes in certain plasmid resident properties o...

Since 2017, Populus cathayana in Shuangshu Nursery, Huzhu County, Qinhai Province has suffered from extensive necrosis of branches, yellow pith tissue, cracks bark to severe cases, brown mucus outflow summer, yellowish pith, and no obvious disease. In this study, symptom observation, specimen collection, pathogen isolation culture, morphological observation molecular biological identification w...

Nitrate pollutants increase the growth of algal bloom, resulting in fresh water eutrophication. The high nitrogen level in wastewater has become a growing concern, which has risen the necessity to develop efficient nitrogen removal techniques. Biological denitrification, which is the reduction of oxidized nitrogen compounds like nitrate or nitrite to gaseous nitrogen compounds, is the most impo...

The applicability of the Elzone particle counter to the determination of marine bacterial biomass was investigated. The biomass of bacterial pure cultures and a mixed natural population were followed by using the particle counter, a CHN analyzer, and an ATP analyzer. The particle counter showed the precise size distribution of number and volume of submicron-size particles in seawater. For the p...
