本文描述了应用于商业性微生物产品Para－Bac中的精选微生物，在含有石油石蜡的厌氧环境中其生存和繁殖能力。在严格的无氧且氧化还原电势国200mV或更低的环境中，产品在原油或正十六烷或正十八烷作为唯一碳源的化学介质中，呈现比24小时中若干传送大4双倍的速率，这些项合到一起产生生物表面活性剂类的活动。本文描述了厌氧环境下在各种不同原油中联合降低粘度和界面张力的能力。这些性质与油田现场实例中获得的结果密切相关。
This article describes selected microorganisms used in Para-Bac, a commercial microbial product, for their ability to survive and reproduce in an anaerobic environment containing petroleum paraffins. In a strictly oxygen-free and redox potential environment of 200 mV or lower, the product exhibits a transport of several 4-fold more than in 24 hours in a chemical medium of crude oil or n-hexadecane or n-octadecane as the sole carbon source Fold, these items come together to create biosurfactant-like activities. This article describes the ability to jointly reduce viscosity and interfacial tension in a variety of different crude oils under anaerobic conditions. These properties are closely related to the results obtained in field examples.
