For many years bacteriologists have observed that some bacteria produce acid from carbohydrates only under aerobic conditions while others produce acid both under aerobic and anaerobic conditions. The significance of these observations does not seem to have been appreciated generally by taxonomists. Studies of bacterial physiology have made it increasingly evident that the bacterial metabolism ...

Aims Coronary heart disease is one of the leading causes of mortality in modern societies. The disease is associated with the lack of physical activity and the expression of some genes involved in blood cholesterol transportation. Adenosine triphosphate (ATP)-binding cassette transporters G5/G8) ABCG5 and ABCG8) is the expression of adenosine triphosphate-dependent box protein genes 5 and 8, a ...

[reaction: see text] The addition of Cs(2)CO(3) and t-BuOH provides a dramatic rate acceleration in the palladium-catalyzed aerobic oxidative kinetic resolution of secondary alcohols while maintaining the selectivity of the process.

Under stationary and anaerobic conditions, greater cell yields of Lactobacillus brevis were obtained from autoclaved than from filter-sterilized glucose media. Fructose, tentatively identified as a product generated by the heating process, served as an excellent catalyst for inducing growth. The addition of micromolar quantities of pentoses or potential pentose precursors to the filter-steriliz...

The simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process was validated to potentially remove ammonium and COD from wastewater in a single, oxygen-limited, non-woven rotating biological contactor (NRBC) reactor. An ammonium conversion efficiency of 79%, TN removal efficiency of 70% and COD removal efficiency of 94% were obtained with the nitrogen and COD loading rate of...

Metal-free, operationally simple, and highly efficient one-pot aerobic process for the synthesis of functionalized/annulated quinolines is devised from easily available 2-aminobenzyl alcohol/2-aminobenzophenones and alkyl/aryl alcohols for the first time. The process involves two sequential reactions, namely in situ aerial oxidation of alcohols to the corresponding aldehydes/ketones followed by...

Mitochondria are dynamic organelles, intricately designed to meet cellular energy requirements. To accommodate alterations in demand, mitochondria have a high degree of plasticity, changing response transient activation numerous stress-related pathways. This adaptive is particularly relevant highly metabolic tissues such as skeletal muscle, where support biological processes related metabolism,...

Abstract The degradability of conventional plastic packaging specimens made from PP and PET, that were produced with novel prodegradant additives, was investigated during biological waste treatment processes. additives merchandised to foster the degradation commodity plastics by enzymatic or abiotic Four different two evaluated for their biodegradability anaerobic aerobic conditions. Aerobic in...
