A combined chemical-biological treatment of industrial wastewater using ozonation as the first step of a Sequencing Batch Biofilm Reactor (SBBR) process, in which 3-methylpyridine (3MEP) was degraded as a model industrial pollutant, has been developed. The ...
Linear alkylbenzene (LAB) cable oils are used for the electrical insulation of high-voltage underground power cables. Due to thermal movement of the cables, leaks can occur at the joints, resulting in cable oil leaking into the surrounding environment. A r ...
M. thermoautotrophicum was grown on a defined mineral salts medium under strictly anaerobic conditions with H2 and CO2 as the sole energy and C sources, resp. The cultivation medium was optimized with respect to non-org. components, including Se(IV), W(VI) ...
To meet the need for studies of anaerobic microbial and animal cell cultures involving much lower heat effects as compared to aerobic microbial cultures, a bench scale calorimeter, Bio-RCl, has been improved for achieving a higher long-term sensitivity. Th ...
The whi2 mutation in S. cerevisiae allows mutant cells to grow with a higher specific rate and at smaller cell sizes at the onset of EtOH metab. in diauxic growth. S. cerevisiae Whi2+ and whi2 were cultivated in aerobic and anaerobic batch cultures in the ...
In Escherichia coli, sn-glycerol-3-phosphate can be oxidized by two different flavo-dehydrogenases, an anaerobic enzyme encoded by the glpACB operon and an aerobic enzyme encoded by the glpD operon. These two operons belong to the glp regulon specifying th ...
M. thermoautotrophicum was grown on a defined mineral salts medium under strictly anaerobic conditions with H2 and CO2 as the sole energy and C source, resp. The cultivation medium was optimized with respect to inorg. components, including Se(IV), W(VI), N ...
A review with 21 refs. on the strategy of wastewater treatment in org. chem. industry. Biodegradability tests, toxicity tests, aerobic and anaerobic treatment processes, and electrochem. oxidn. of org. substances are discussed with an example of a pilot pl ...
The heat generated by both batch and continuous cultures of the yeast Kluyveromycs fragilis was studied using a modified bench scale calorimeter. Batch cultures were used to measure the heat dissipation rates and the heat yields during fully aerobic and co ...
Sedimentation of solids is accelerated and complete, resulting in a high-quality effluent, when a 0.1% soln. of equal parts of poly(dimethyl-diallyl-ammonium chloride) cationic flocculant and a nonionic or anionic polyacrylamide is used at a rate of 0.25-4 ...
