The invention provides a strain of
Geobacillus thermodenitrificans as well as the
screening method and the uses thereof. The strain was deposited as the number CGMCC-1228 in the China General
Microbiological Culture Collection Center of the China Committee of Culture Collection for Microorganisms. The strain was obtained by
primary screening, re-screening,
inoculation,
domestication and propagation using the
bacteria in the aqueous samples from the strata of
oil field as the original screening strain. The strain screened in the invention belongs to the
genus Geobacillus, which can tolerate a high temperature, and has good
thermostability, which can be applied to the industrial production which need the condition of
thermostable enzymes, such as
fermentation, etc. With its ability of growing well in the oil-reservoir environment, degrading alkanes, decreasing
viscosity and increasing fluidity of
crude oil, the strain is able to remarkably enhance the yield of oil and improve the transporting efficiency of oil. Additionally, with its good ability of degrading oil, it can be developed for the treatment and clearing of the material such as the oil
contaminated water, etc., so it can be useful in protection of the environment. This strain also has the ability of decreasing the
surface tension of substances, which can be applied to the industry of biosurfactants preparation.
