Biosynthesis and physiology of coenzyme Q in bacteria.
Ubiquinone, also called coenzyme Q, is a lipid subject to oxido-reduction cycles. It functions in the respiratory electron transport chain and plays a pivotal role in energy generating processes. In this review, we focus on the biosynthetic pathway and physiological role of ubiquinone in bacteria. We present the studies which, within a period of five decades, led to the identification and chara...
متن کاملThe effects of UV radiation in the marine environment
Decreasing concentrations of ozone in the stratosphere radically influence the effects ofUV radiationon the environment.This bookprovides a comprehensive review of UV radiation effects specifically in the marine environment. A multidisciplinary approach is adopted to discuss all aspects from physical, chemical and biological perspectives. The book begins by describing the attenuation of UV radi...
متن کاملProduction of coenzyme Q by hydrocarbon-assimilating bacteria.
(pH 7.0) in the following medium: 5% nhexadecane (Tokyo Kasei Co., Tokyo, Japan), 0.1% KH2PO4, 0.4% (NH4)2S04, 0.05% FeSO4 7Hq0, 0.05% MgS04-7H20, and 0.4% yeast extract (Difco). A total of 10.4 g of dry cells was obtained from 2 liters of culture broth in 2 days at 30 C. The CoQ fraction was extracted as described by Lavate et al. (3). A 1-ml amount of the nonsaponifiable extract was taken up ...
متن کاملEnhanced UV radiation – a new problem for the marine environment
UV irradiance at the earth’s surface is intimately related to stratospheric ozone. This gas tends to be concentrated in the lower stratosphere (hence the notion of an ozone layer) and is primarily responsible for the absorption of solar UV radiation (UVR). UVR has been recognised for many years (e.g. Worrest, Dyke & Thomson, 1978; Worrest et al., 1981; Calkins, 1982) as a potential stress for o...
متن کاملEffect of coenzyme Q10 on radiation-induced fatigue in rats
Background: Fatigue is a common side effect in cancer patients undergoing radiation therapy (RT). Radiation-induced fatigue affects the quality of life, but there is no definitive treatment option. In this study, the weight-loaded forced swim test was performed to assess the effect of coenzyme Q10 (CoQ10) on radiation-induced fatigue. Materials and Methods: A total of 60 rats were divided rando...
