Summary
Bacillus amyloliquefaciens B-1895 improved broiler performance. This new formulation enhanced live mass by 7-8% and improved feed conversion by up to 8.8% in broilers.
Area of Science:
- Animal Science
- Microbiology
Background:
- Bacillus amyloliquefaciens B-1895 is a beneficial microorganism.
- Soybean fermentation can enhance the delivery of microbial spores.
Purpose of the Study:
- To evaluate the efficacy of a novel Bacillus amyloliquefaciens B-1895 formulation in solid-state fermented soybean for broiler growth.
- To assess the impact of the formulation on broiler mass dynamics and feed conversion.
Main Methods:
- Broilers were administered a new formulation containing Bacillus amyloliquefaciens B-1895 spores in solid-state fermented soybean.
- Live mass, feed flow rate, and broiler performance were monitored throughout the study.
- Feed conversion ratio was calculated based on live mass gain.
Main Results:
- Broilers receiving the formulation showed consistently greater live mass compared to the control group, with a 7-8% increase by day 28.
- Feed conversion per kilogram of live mass improved significantly, ranging from 1.81-1.87 kg in experimental groups versus 1.97 kg in controls (5.3-8.8% difference).
Conclusions:
- The Bacillus amyloliquefaciens B-1895 formulation positively impacts broiler live mass.
- The formulation enhances feed consumption efficiency in broilers, indicating its efficacy in improving growth performance.

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...

Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...

Penicillin, one of the earliest and most widely used antibiotics, is produced industrially by the filamentous fungus Penicillium chrysogenum. Large stirred-tank bioreactors ranging from tens to hundreds of thousands of liters maintain tightly controlled temperature, pH, and dissolved oxygen conditions to support fungal metabolism and maximize antibiotic yield. Penicillin is a secondary metabolite, synthesized primarily during the stationary growth phase, which requires a carefully managed...
