The microbacterium sp. strain is capable of efficiently degrading phenols in wastewater, and also is capable of tolerating a phenol-containing solution with the phenol concentration up to 2500 mg / L.

The invention discloses sophora tonkinensis endogenetic bacterium B22. The sophora tonkinensis endogenetic bacterium B22 has the type name of Microbacterium sp. B22, a 16S rDNA gene sequence table of the Microbacterium sp. B22 is as shown in SEQ ID NO. 1, and the Microbacterium sp. B22 is collected by the General Microorganisms Center of China Committee for Culture Collection of Microorganisms, which is located at Institute of Microbiology, Chinese Academy of Sciences, 3#, 1# Courtyard, Beichen West Road, Chaoyang District, Beijing, on September 29, 2015 and has the collection number of CGMCC No. 11463. According to the sophora tonkinensis endogenetic bacterium B22, the endogenetic bacterium Microbacterium sp. B22 is obtained through being separated from roots of a medicinal plant, i.e., Sophora tonkinensis and carrying out screening for the first time and has a powerful inhibiting action on Alternaria panax Whetzel, and thus a broad application prospect is brought to the field of biological control on panax notoginseng fungal diseases.

The invention relates to a method for improving a crude oil recovery ratio in a dolomite reservoir by using microbial flora, wherein the microbial flora include pseudomonas aeruginosa, bacillus cereus, bacillus subtilis, microbacterium sp., escherichia coli, pseudomonas putida and bacillus licheniformis; the microbial flora are compounded according to the ratio, and through expansion culture and fermentation culture, a fermentation liquid of the microbial flora is prepared; the fermentation liquid is mixed with injected water, a nutrient solution is added into the mixed solution, the mixed solution is injected into a dolomite reservoir core, and after the injected microbial flora act on the dolomite reservoir core, crude oil recovery is performed. The microbial flora can increase the core pore diameter, length and porosity, and lowers the crude oil viscosity and oil-water interfacial tension, so as to improve the crude oil recovery ratio of the dolomite reservoir; moreover, the method has the advantages of simple fermentation process, low cost, simple operation, and high input / output ratio, is suitable for large-scale industrial production, and has good application prospects.

The invention discloses mixed bacteria for promoting acacia nodulation and nitrogen fixation and an application thereof, which belong to the technical field of microorganisms. The mixed bacteria can be prepared from Kocuria sp. X-22, Microbacterium sp. X-26 and Bacillus sp. X-28, all the bacteria are preserved in the China Center for Type Culture Collection (CCTCC), the preservation numbers are CCTCC No: M 2019237, CCTCC No: M 2019238, and CCTCC No: M 2019239 respectively. The mixed bacteria are added to the periphery of the acacia seedlings, and compared with a single-bacteria treatment groupand a sterile treatment group, the synergistic superposition effect can be achieved, the nodulation rate and symbiotic nitrogen fixation level of acacia are obviously increased, and photosynthesis ofacacia is promoted.
