The invention discloses a salt-tolerant microbial agent and a preparation method thereof. The microbial agent contains staphylococcus cohnii FSND-C, arthrobacter creatinolyticus FDN-1, flavobacterium mizutaii FDN-2, paracoccus denitrificans DN-3 and methylobacterium phyllosphaerae SDN-3. The microbial agent can achieve removal of ammonia nitrogen, total nitrogen and CODcr in the same reactor, has a good wastewater treatment effect, and can achieve short-cut nitrification and denitrification or simultaneous nitrification and denitrification while removing COD. Staphylococcus cohnii FSND-C can utilize various carbon sources, has certain salt tolerance, can be applied to the high-salinity wastewater treatment process, simultaneously can secrete a substance under environmental stimulus to enhance the flocculability of sludge, and further widens the application range of the microbial agent.

The invention relates to a biological denitrification method for salt-containing sewage, which comprises the following steps: adding a denitrification microbial inoculant into a biochemical sewage treatment system, and simultaneously starting the nitrification-denitrification biological denitrification treatment processes, wherein the sewage treatment temperature is 18-40 DEG C, the dissolved oxygen is 0.1-5 mg/L, and the pH value is 7.0-9.0. The denitrification microbial inoculant contains one or two of Staphylococcuscohnii FSDN-C, Arthrobactercreatinolyticus FDN-1 and Flavobacteriummizutaii FDN-2, and also contains one or two of Paracoccusdenitrificans DN-3 and Methylobacteriumphyllosphaerae SDN-3. The method provided by the invention can effectively treat high-salt-content sewage, enhances the adsorptivity and flocculence for sludge, has wide application range for wastewater quality and high impact resistance to salt-containing sewage, and obviously enhances the sewage treatment effect on the premise of removing pollutants, such as ammonia nitrogen, COD (chemical oxygen demand) and the like.

The present invention discloses a short-cut nitrification-denitrification microbial agent. The microbial agent contains Arthrobacter creatinolyticus FDN 1, Flavobacterium mizutaii FDN 2, Paracoccus denitrificars DN 3 and Methylobacterium phyllosphaerae SDN3. The preservation register numbers of the four strains respectively are CGMCC No.3657, CGMCC No.3659, CGMCC No.3658 and CGMCC No.3660. With the microbial agent, the ammonia nitrogen removing, the total nitrogen removing and the CODcr removing in the same reactor can be achieved, the wastewater treatment effect is good, and the microbial agent is especially suitable for the purification treatment of the wastewater containing the ammonia nitrogen so as to really achieve the short-cut nitrification-denitrification or simultaneous nitrification and denitrification.

Methylotrophic or methanotrophic bacteria such as Methylobacterium are transformed with a gene of interest, and expression of the gene is regulated by means of a cumate repressor protein and an operator sequence which is operatively linked to the gene of interest, and the addition of an external agent. Specifically, the cymR repressor and cmt operator from Pseudomonas putida may serve to regulate gene expression in methylotrophic or methanotrophic bacteria with the addition of cumate.

The invention relates to novel Methylobacterium species that are capable of degrading nitroaromatic and nitramine compounds. Compositions, kits and methods of using the Methylobacterium species for the degradation of nitroaromatic and nitramine pollutants are provided. More specifically, compositions and methods for the degradation or bioremediation of nitroaromatic and nitramine explosives and explosive residues are provided.

The invention relates to the technical field of biology, in particular to methylobacterium thermophilum. The preservation number of the methylobacterium thermophilum is CGMCC No. 20326. The methylobacterium thermophilum can utilize heat generated by the fermentation of compost raw materials as a heat source for propagation and growth, the highest growth temperature is up to 77 DEG C or above, themethylobacterium thermophilum can quickly proliferate in a high-temperature composting environment, and organic matters are degraded to promote the composting process, do that the dual effects of heatenergy utilization and waste treatment are achieved; in addition, microbial inoculum prepared from bacterial strains has low water content, so that storage and transportation are facilitated; the microbial inoculum can be directly mixed with a stacked material during use, so that operation is convenient, and the water content of the material is not increased; and the microbial inoculum is a goodwet-based material conditioner, and has wide application value.

The invention relates to the technical field of indoor air purification, and particularly discloses a method for efficiently degrading indoor formaldehyde. The method comprises the steps of S1, activating methyl bacillus, pseudomonas and rhodopseudomonas palustris for later use; S2, inoculating activated methylobacterium and activated pseudomonas into a liquid culture medium A, culturing for 12-18hours, inoculating activated rhodopseudomonas palustris into the liquid culture medium A, and culturing in a dark environment with formaldehyde; S3, co-culturing the microorganisms and green plants,and adding an amino acid solution into a culture solution to obtain potted plants capable of degrading indoor formaldehyde; and S4, adding the amino acid solution into the potted plants every other 2-20 days. The method disclosed by the invention has the advantage of efficiently degrading indoor low-concentration formaldehyde.

The invention provides a strain of methylorubrum rhodesianum M520. The methylorubrum rhodesianum M520 is preserved in the Guangdong Microbial Culture Collection Center, and the preservation number isGDMCC No.60729. The invention also provides an application of the M520 strain to preparation of a preparation for preventing and controlling root-knot nematodes or promotion of plant growth. When a metabolism crude extract of the methylorubrum rhodesianum M520 strain is applied to the root-knot nematodes, the lethal rate of the root-knot nematodes exceeds 96.6%; and in addition, a fermentation culture of the strain has an obvious promotion effect on growth of vegetable plants while effectively preventing and controlling the root-knot nematodes of potted vegetables, the use range and efficacy of methylobacterium are expanded, the prevention and control measures of a root-knot nematode disease is enriched, and the growth rate and vegetable yield of the vegetable plants are improved.
