The application provides a method for treating and recycling iron-containing waste sulfuric acid in titanium dioxide production, which is based on screening of a strain capable of treating iron-containing waste water in a low pH environment, and establishes a method for treating iron-containing waste sulfuric acid, which can effectively realize resource recycling. The waste water treatment bacteria used are Bacillus QD-QJ-062 strain, and the preservation number is CGMCC No.33725. The QD-QJ-062 strain of Bacillus screened by the application can effectively treat the iron-containing waste water in a low pH environment, promote the generation of ferrous oxalate precipitation, and generate ferrous oxalate by-products. The generated ferrous oxalate can be converted into ferrous sulfate by sulfuric acid, and oxalic acid can be recycled, thereby reducing the operation cost. The sulfuric acid solution after iron removal can be neutralized by limestone to generate high-purity gypsum, thereby realizing resource recycling and treatment.

This invention discloses a method for coupling physicochemical treatment and biodegradation of plastics. The method includes the following steps: S1. Mixing plastics, organic solvents, and a metal catalyst, and reacting to degrade them to obtain organic products. The metal catalyst is cobalt acetate and / or manganese acetate; S2. Biodegrading the organic products from step S1 using a mixed colony, which includes *Pseudomonas*, *Bacillus*, *Flavobacterium*, and *Rhodococcus*. This invention uses cobalt acetate and / or manganese acetate as metal catalysts. The catalytic oxidation of the metal catalyst can efficiently depolymerize traditional plastics, overcoming the bottleneck of C-C bond breaking that is difficult for microorganisms to achieve. It can successfully convert plastics into organic products mainly composed of dicarboxylic acids, benzoic acid, and terephthalic acid, and the mixed colony process completely mineralizes the organic products. This method achieves complete removal of plastics without producing any toxic or harmful substances.

The application relates to the technical field of microbial remediation methods, and specifically discloses an ex-situ microbial remediation method for river sewage, aiming to solve the multiple contradictions of redundancy of existing ex-situ microbial remediation technology, single function of bacterial flora, weak environmental adaptability and difficulty in giving consideration to high efficiency and engineering simplicity. The method comprises the following steps: guiding the river sewage out and pretreating the river sewage to remove large-particle impurities; introducing a biological reactor to inoculate a composite functional bacterial flora composed of the genus Raoultella, the genus Pseudomonas and the genus Bacillus in proportion; implementing gradient dissolved oxygen regulation to realize simultaneous nitrification and denitrification; adding iron-manganese modified biochar as a microbial carrier and an electron mediator; and recycling the biochar after solid-liquid separation and reaction. Through the above technical scheme, the application can realize multi-target and simultaneous high-efficiency removal of ammonia nitrogen, refractory organic matter and trace heavy metals, simplify a process flow, improve system stability and low-temperature adaptability, and support modular deployment and intelligent operation and maintenance.

This invention relates to the field of microbial self-assembled protein fibrils as novel bionanomaterials. More specifically, this invention relates to protein nanofibril materials comprising Bacillus endospore appendage (ENA) proteins, which are spontaneously folded helical hairpin subunits assembled into α-helical multimers (A-ENA) fibrils having a hydrophobic core and covalently linked by one or more isopeptide bonds, providing nanofibrils with high stability and tensile strength. This invention also relates to said protein nanofibrils being engineered or modified to provide functionalized bionanomaterials. In particular, this invention relates to methods for the recombinant preparation of said self-assembled protein nanofibrils, and their use in modifying bacterial endospores and endospore activity or pathogenicity.

This invention discloses a strain of *Bacillus halophilus* and its application in promoting sesame growth and improving salt and alkali tolerance, belonging to the field of sesame cultivation technology. This strain of *Bacillus halophilus* is... Halobacillus sp. OCR1-S1, with the preservation number CCTCC NO:M 20252396. Experiments showed that inoculation with the OCR1-S1 strain during the sesame germination stage under salt-alkali stress significantly promoted the growth of fresh weight, root length, and shoot length in sesame buds; inoculation with the OCR1-S1 strain during the sesame seedling stage significantly enhanced the sesame's resistance to salt-alkali stress; simultaneously, treatment of sesame roots with the OCR1-S1 strain under normal soil conditions also promoted sesame plant growth and increased phosphorus content. This invention provides a new microbial resource and a reliable solution for sesame to cope with salt-alkali stress, and is of great significance for utilizing my country's large areas of saline-alkali land to meet the needs of sesame industry expansion.

This invention discloses a method for controlling root rot in Panax notoginseng based on a cross-species synthetic community and its application, belonging to the field of agricultural biological control. This cross-species synthetic community consists of a specific ratio of Bacillus bacteria and Trichoderma fungi. Biological agent capsules are prepared and applied as a basal soil treatment before planting. At the time of Panax notoginseng emergence, 5-10 capsules (equivalent to 100-200 mg per plant) are buried in each planting hole. The capsules slowly release the microbial community in the soil for 2-3 months. This synthetic community can significantly reduce the incidence of root rot in Panax notoginseng, promote plant growth, and increase the content of Panax notoginseng saponins. It achieves comprehensive control by inhibiting pathogens, reshaping the rhizosphere microecology, activating plant immunity, and regulating metabolism. It is suitable for green planting of Panax notoginseng and the management of continuous cropping obstacles, possessing both high efficiency and ecological safety.
