The Mycobacteria sp. has significant nitrogen fixation, carbon fixation, and ammonia oxidation capacity, can directly oxidize ammonia nitrogen into nitrogen, and has an antagonistic effect on other microorganisms.

Disclosed herein are compositions comprising A) compound of Formula One (F1) or Formula Two (F2); and B) biological agent selected from the group consisting of Bacillus species, Baclovirus species, Pseudomonas species, Beauveria species, Mycobacterium species, Mycorrhizal fungi, Trichoderma species, and Metarhizium species.

This invention relates to the field of microbial inoculants, and particularly to a compound inoculant for controlling soil-borne diseases in farmland based on endophytic bacteria, and its preparation method. The compound inoculant is composed of a main inoculant, auxiliary inoculants, and a fungicide. The main inoculant includes *Talaromyces sp. strain HBUM07170*, *Rhizobium sp. NXC24*, and *Methylobacterium brachiatum*, while the auxiliary inoculants include *Mycobacterium sp.*, *Caulobacter sp.*, *Penicillium sp.*, and *Pyronema omphalodes*, with each strain having a concentration of not less than 10%. 8 The concentration of CFU / ml is 1:1 (main bacterial agent mixture to auxiliary bacterial agent mixture), and tebuconazole is used as the fungicide. During preparation, each bacterial strain is activated and cultured separately, then mixed according to the specified volume ratio before adding tebuconazole and stirring to dissolve. This invention's compound bacterial agent exhibits synergistic effects among the bacterial strains, effectively antagonizing Fusarium oxysporum, reducing the incidence and mortality of lily wilt, and promoting plant growth. It combines biological control with chemical-assisted antibacterial effects and can be used in the preparation of control formulations for soil-borne diseases in farmland and lily wilt.

The invention provides a method for synchronously converting hydrogen sulfide and sulfate radicals into elemental sulfur and sulfur-containing amino acid. The method comprises the following steps: in an aerobic state, pH value is lt; the method comprises the following steps: under the conditions that the concentration of sulfur ions is greater than or equal to 1.5 and the concentration of SO4 < 2-> is greater than or equal to 2g / L, enriching microbial florae containing mycobacteria, so that the oxidation reaction of hydrogen sulfide and the reduction reaction of sulfate radicals are synchronously carried out to obtain elemental sulfur and sulfur-containing amino acid. According to the method, two metabolic pathways of sulfur oxidation and sulfate reduction are ingeniously combined, efficient utilization and resource recycling of sulfur elements in hydrogen sulfide gas and sulfate wastewater are achieved through microbial flora containing mycobacteria, and an innovative, efficient and environment-friendly solution is provided for high-value recycling of sulfur-containing waste; and a new way is opened up for the application of the biotechnology in the treatment of extreme industrial wastes.
