The invention relates to a highly tolerant organic sulfur halophilic bacillus, the high organic sulfur tolerant halophilic bacillus is named as the BDH06 strain of Thioalkalibacter halophilus, and the preservation unit is China Microbial Bacteria The General Microbiology Center of the Species Preservation Management Committee, the preservation time is June 10, 2020, the preservation number is CGMCC No. 20058, and the address is: No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing. The strain has high tolerance to organic sulfur, and has the ability to oxidize sulfur hydride to generate elemental sulfur under the conditions of high salt, high alkali and high organic sulfur. The yield of elemental sulfur is over 80%, and the removal rate of hydrogen sulfide It reaches more than 99%, which significantly improves the tolerance of the system to organic sulfur and expands the application range of biological desulfurization technology.

The invention relates to the technical field of microorganisms. Specifically, the present invention relates to a halophilic tetrad, which can significantly increase the content of 4-vinylguaiacol in soy sauce or sauce, thereby increasing the aroma of soy sauce and improving the flavor quality. Therefore, the present invention also relates to a method for preparing soy sauce or miso, which comprises adding the tetradococcus halophilus of the present invention before or during the fermentation of moromi.

The invention relates to a method for cultivating halophilic granular sludge, which belongs to the field of sewage biological treatment. The principle of the invention is as follows: (1) rapidly increasing the influent load to stimulate EPS secretion of halophilic microorganisms. Microorganisms attach and grow through the binding of EPS, and form mature halophilic active granular sludge under the action of hydraulic shear force; (2) The combined effect of long and short settling time. The long precipitation time in the early stage can achieve the growth of halophilic microorganisms in the reactor; the short precipitation time in the later stage can provide selective pressure for granulation. The halophilic activated granular sludge cultivated in the present invention has various sludge sources and simple technology. Since the enriched microorganisms come from the halophilic bacteria group deposited in the estuary, the salinity tolerance range is between 1% and 10%. And can retain the compact shape structure. It greatly shortens the precipitation time, effectively shortens the treatment cycle and ensures the treatment effect, realizes the rapid treatment of high-salt wastewater, realizes short-range nitrification, and reduces energy consumption by 30%.

The invention provides a composite strain for treating high-salt wastewater. In particular, the method comprises transferring a halophilic related gene into a specific microorganism; after the obtained halobacteria are added into a deep biochemical pool, the microbial life in background sludge in the deep biochemical pool is not affected. The halobacteria are resistant and degradable to high-salt,high-chlorine, high-alkali sewage, and have a function of treating sewage having poor biodegradability, the single bacteria performance is stable, and the performance can be passed through genetic modification, which is specially suitable for industrial scenes with deep sewage treatment needs.

The invention provides a halophilic autotrophic desulfurized bacterial strain having the maximum tolerance to a 14% mixed solution of Na2CO3 and NaHCO3. The bacterial strain is named as NPE-1, and the preservation number is CCTCC NO: M 2015152. The bacterial strain can normally grow in the 7%-10% mixed solution of Na2CO3 and NaHCO3, hydrogen sulfide is converted into elemental sulfur, and the desulphurization rate can be up to 0.2-0.3 g(H2S) / (L.h). The bacterial strain has very good hydrogen sulfide load-resisting capacity and high pH resistance performance, can normally grow under the pH condition of 10.5-11 and can treat gas with the hydrogen sulfide concentration of 5000-20000 ppm. A generation cycle is short and is only 40 minutes, and the sundry bacterial resistance is strong. The invention further provides application of the halophilic desulfurized bacterial strain in biological desulphurization. The halophilic desulfurized bacterial strain can efficiently convert the hydrogen sulfide into the elemental sulfur, and also has very high halophilism, accordingly wastewater discharge and alkali liquid consumption are remarkably reduced, the operation cost of biological desulphurization is greatly reduced, the stability of a biological desulphurization system is improved, a solid foundation is laid for industrial application of a washing tower type biological desulphurization technology, and the bacterial strain is suitable for large-scale popularization and application.

The invention provides a method for obtaining halophilic bacteria with a high-salt wastewater treatment function. The method particularly includes transferring a halophilic related gene into a specific microorganism. After the obtained halophilic bacteria are added to a deep biochemical pool, the microbial life in background sludge in the deep biochemical pool is not affected. The halophilic bacteria are resistant and degradable to high-salt high-chlorine and high-alkali wastewater, and can treat the wastewater with poor biodegradability and have stable single bacteria performance. The performance can be subjected to passage by means of genetic modification, and the method is especially suitable for industrial scenes with deep sewage treatment demand.
