Bacillus Firmus
SINOBIO
3808919090
Product Name: Biological Bacterial Fertilizer Bacillus Firmus Kill Nematodes
Common Name: Bacillus Firmus
Bacteria Count: 100 billion live spores/gram, Wettable Powder
Common Crops: Rice, corn, wheat, soybeans, grapes, tomatoes, potatoes, cotton tomatoes, cucumbers, sweet oranges, etc.
Bacillus firmus (Bacillus firmus) is a genus of Gram-positive, non-pathogenic bacillus bacteria. Its core advantages lie in three areas: agricultural biocontrol, industrial enzyme production, and environmental adaptability. A detailed analysis follows:
1. Broad-spectrum antimicrobial activity
Pathogen inhibition: It exhibits significant inhibitory effects on 14 plant pathogenic fungi, including cucumber powdery mildew, walnut anthracnose, wheat root rot, and corn leaf spot fungus, with inhibition rates ranging from 60% to 83.33%.
Mechanism of action: By secreting non-volatile metabolic products (such as polysaccharides, crude fats, and proteins), it disrupts the structure of fungal hyphae walls, causing hyphae swelling, deformation, twisting, and even protoplasm leakage.
Example: The Bacillus subtilis Bf-02 strain achieves over 80% efficacy in controlling walnut anthracnose, with a 25 billion CFU/g wettable powder formulation showing efficacy rates of 75.69%–80.91% 14 days after the final application.
2. Biological insect and nematode control
Pest control: It achieves a 100% mortality rate against yellow striped flea beetles within 48 hours and can also suppress soil-borne diseases such as tomato root-knot nematodes and rice sheath blight.
Market application: BASF's biological nematicide Votivo Prime uses Bacillus subtilis as its core component, reducing nematode populations and promoting root growth through seed treatment, and is suitable for crops such as rice, soybeans, and corn.
1. Amylase activity
Bacillus subtilis can clone and express genes with β-amylase characteristics, and its starch hydrolysis products are mainly maltose, with enzyme activity reaching 9000 U.
Thermal Stability: Some strains (e.g., the enzyme encoded by pBA135) retain over 70% of their activity after being incubated at 60°C for 30 minutes, with an optimal reaction temperature of 55–60°C, making them suitable for industrial fermentation conditions.
2. Saccharification enzyme applications
As a core component of industrial enzyme preparations, saccharification enzymes produced by Bacillus subtilis are widely used in the food, brewing, and textile industries to reduce production costs and improve efficiency.
1. Salt and Alkalinity Tolerance
Can grow normally in a medium containing 15% sodium chloride, making it suitable for biological remediation projects in saline-alkali soils in China's northwestern regions.
Example: The Bacillus FJW3 strain remains active under extreme conditions of pH 3-10 and 15% salt concentration.
2. Temperature and pH Tolerance
Optimal growth temperature is 28–30°C, with a pH range of 6.0–7.0. Some strains can survive in acidic environments with a pH of 3, adapting to various industrial fermentation requirements.
1. Biosafety Level
Bacillus subtilis is classified as a Category IV non-pathogenic bacterium, with no pathogenicity to plants or animals. The original isolation medium was a common soil sample, and no special toxic components were detected.
2. Commercial Applications
Strain Preservation: Multiple strains (e.g., S101, Bf-02, FJW3) are preserved at the China General Microbial Culture Collection Center (CGMCC) and the China Type Culture Collection Center (CCTCC).
Product Forms: Sold in forms such as freeze-dried powder, slants, and bacterial solutions, with price ranges from 300 to 1,200 RMB per vial, suitable for research, education, and industrial production.
