Biodeterioration of crude oil and oil derived products: a review 总被引:2,自引:0,他引:2
Natalia A. Yemashova Valentina P. Murygina Dmitry V. Zhukov Arpenik A. Zakharyantz Marina A. Gladchenko Vasu Appanna Sergey V. Kalyuzhnyi 《Reviews in Environmental Science and Biotechnology》2007,6(4):315-337
Biodeterioration of crude oil and oil fuels is a serious economic and an environmental problem all over the world. It is impossible
to prevent penetration of microorganisms in oil and fuels both stored in tanks or in oilfields after drilling. Both aerobic
and anaerobic microorganisms tend to colonise oil pipelines and oil and fuel storage installations. Complex microbial communities
consisting of both hydrocarbon oxidizing microorganisms and bacteria using the metabolites of the former form an ecological
niche where they thrive. The accumulation of water at the bottom of storage tanks and in oil pipelines is a primary prerequisite
for development of microorganisms in fuels and oil and their subsequent biological fouling. Ability of microorganisms to grow
both in a water phase and on inter-phase of water/hydrocarbon as well as the generation of products of their metabolism worsen
the physical and chemical properties of oils and fuels. This activity also increases the amount of suspended solids, leads
to the formation of slimes and creates a variety of operational problems. Nowadays various test-systems are utilized for microbial
monitoring in crude oils and fuels; thus allowing an express determination of both the species and the quantities of microorganisms
present. To suppress microbial growth in oils and fuels, both physico-mechanical and chemical methods are applied. Among chemical
methods, the preference is given to substances such as biocides, additives, the anti-freezing agents etc that do not deteriorate
the quality of oil and fuels and are environmentally friendly. This review is devoted to the analysis of the present knowledge
in the field of microbial fouling of crude oils and oil products. The methods utilized for monitoring of microbial contamination
and prevention of their undesirable activities are also evaluated. The special focus is given to Russian scientific literature
devoted to crude oil and oil products biodeterioration. 相似文献

Tropomyosin (Tpm) is an α-helical coiled-coil actin-binding protein that plays a key role in the Ca2+-regulated contraction of striated muscles. Two Tpm isoforms, α (Tpm 1.1) and β (Tpm 2.2), are expressed in fast skeletal muscles. These Tpm isoforms can form either αα and ββ homodimers, or αβ heterodimers. However, only αα-Tpm and αβ-Tpm dimers are usually present in most of fast skeletal muscles, because ββ-homodimers are relatively unstable and cannot exist under physiologic conditions. Nevertheless, the most of previous studies of myopathy-causing mutations in the Tpm β-chains were performed on the ββ-homodimers. In the present work, we applied different methods to investigate the effects of two myopathic mutations in the β-chain, Q147P and K49del (i.e. deletion of Lys49), on structural and functional properties of Tpm αβ-heterodimers and to compare them with the properties of ββ-homodimers carrying these mutations in both β-chains. The results show that the properties of αβ-Tpm heterodimers with these mutations in the β-chain differ significantly from the properties of ββ-homodimers with the same substitutions in both β-chains. This indicates that the αβ-heterodimer is a more appropriate model for studying the effects of myopathic mutations in the β-chain of Tpm than the ββ-homodimer which virtually does not exist in human skeletal muscles. 相似文献
