Bacillus safensis is a Gram-positive, spore-forming, and rod bacterium, originally isolated from a spacecraft in Florida and California. B. safensis could have possibly been transported to the planet Mars on spacecraft Opportunity and Spirit in 2004. There are several known strains of this bacterium, all of which belong to the Firmicutes phylum of Bacteria. This bacterium also belongs to the large, pervasive genus Bacillus. B. safensis is an aerobic chemoheterotroph and is highly resistant to salt and UV radiation. B. safensis affects plant growth, since it is a powerful plant hormone producer, and it also acts as a plant growth-promoting rhizobacteria, enhancing plant growth after root colonization. Strain B. safensis JPL-MERTA-8-2 is (so far) the only bacterial strain shown to grow noticeably faster in micro-gravity environments than on the Earth surface.
Bacillus safensis H1, culture method and application thereof
This invention discloses a strain of *Bacillus saeformis* H1, its culture method, and its applications, relating to the field of microbial technology. The strain was deposited on March 31, 2026, at the China General Microbiological Culture Collection Center (CGMCC), with accession number CGMCC No. 38117. This strain exhibits strong environmental adaptability, can stably grow under neutral to strongly alkaline conditions, and secretes antibacterial substances with low toxicity and no pathogenicity. After optimization, its optimal liquid fermentation conditions are: 5 g / L yeast extract, 10 g / L peptone, 37 g / L sucrose, pH=10, temperature 25℃, rotation speed 140 rpm, and culture time 24 h. The fermentation supernatant of this strain shows significant inhibitory effects on Gram-positive bacteria such as *Staphylococcus aureus*, methicillin-resistant *Staphylococcus aureus*, and *Streptococcus pneumoniae*, and can be prepared into drug sensitivity tablets. The *Bacillus saeformis* H1 provided by this invention can be used to prepare antibacterial drugs or antibacterial infection drugs, providing a new strategy for alleviating the problem of antibiotic resistance.

Bacillus safensis and application thereof in preventing and treating plant diseases
The application belongs to the field of agricultural microbial technology, and particularly relates to a plant endophytic Bacillus safensis and application thereof in plant disease prevention and treatment. The plant endophytic Bacillus safensis has a strain number of BSA15, a classification name of Bacillus safensis Bacillus safensis , a preservation number of CGMCC No. 36637, and is preserved in the China General Microbiological Culture Collection Center on November 17, 2025. The Bacillus safensis has a broad-spectrum inhibitory activity on pathogenic fungi and oomycetes, and can produce a significant inhibitory effect on plant pathogenic microorganisms through multiple mechanisms. In addition, the Bacillus safensis BSA15 can be stably colonized in the plant body as an endophyte, further enhancing the disease prevention and control effect. Using the strain for disease prevention and treatment can significantly reduce the use amount of chemical pesticides, reduce pesticide residues and environmental pollution, and meet the requirements of green agriculture and sustainable development.

Bacillus safensis and applications thereof
This invention relates to the field of biotechnology, and particularly to a strain of Bacillus salafulae subsp. salafulae and its applications. This invention uses a strain of Bacillus salafulae subsp. salafulae as the core functional bacterium to construct a solid / semi-solid fermentation process window that can operate stably at high temperatures of 30-55℃. Through "high-temperature steady-state enzyme production and hydrolysis + process temperature and humidity control and impurity suppression + optional compatibility for synergistic nitrogen locking / adsorption," low ammonia odor and nutrient release are achieved, resulting in fermented feed products with higher nutrient availability, milder odor, and better batch consistency.

Bacillus safensis hmc19 and application thereof
This invention relates to a type of Bacillus safranin (Sarfus). Bacillus safensis HMC19, with accession number CGMCC No. 35493, can stably colonize in high saline-alkali environments, regulate soil pH, and secrete the plant growth regulator phenylacetic acid, which delays chlorophyll degradation and effectively alleviates premature aging of plants under saline-alkali stress. It achieves synergistic effects of saline-alkali land improvement and crop quality and yield enhancement. It can also effectively degrade soil autotoxic substances such as p-hydroxybenzoic acid and ferulic acid, improve the soil microenvironment, and prevent continuous cropping obstacles.
