Strain Development Safety and Efficacy Fermentation Solution Probiotics Development Probiotic Effects Workflow Why Choose Us?

Bacillus is a type of Gram-positive, rod-shaped bacterium that can form spores. It can thrive in both aerobic and facultative anaerobic conditions and is widely present in nature, including in soil, air, fermented foods, and the gut of animals. The spore form of Bacillus probiotics enables their survival in extreme environmental conditions, allowing them to persist even in circumstances that would typically kill other forms of bacteria. BioVenic offers a comprehensive solution for the development of Bacillus as feed additives for livestock and companion animals. Using our advanced technical platforms, we provide a range of services including probiotic Bacillus strain development, probiotic Bacillus safety and efficacy assessment, probiotic Bacillus fermentation solution, quality control and product development. Our team of probiotics experts is highly skilled and can assist you in the development of Bacillus probiotics with exceptional feasibility and broad applicability.

Probiotic Bacillus Strain Development

  • Bacillus Isolation and Identification

BioVenic offers various methods to isolate and identify potential Bacillus probiotics from the gastrointestinal tracts and feces of different animal species such as chickens, pigs, ruminants, and aquatic animals. Our methods include 16S rRNA gene sequencing, analysis of gyrA or gyrB genes, biochemical tests, and multilocus sequence analysis.

  • Bacillus Genetic Background Research

Using PCR, gene sequencing, and genomic analysis techniques, we help you understand the genetic basis of Bacillus that may contribute to its potential probiotic effects. Whole-genome information analysis allows us to predict its probiotic potential by assessing the ability to produce antimicrobial peptides and extracellular effector molecules.

  • Bacillus Genetic Modification

Through our genetic engineering platform and integrated probiotic development platform, we help researchers obtain genetically stable Bacillus probiotics with desired traits and provide solutions to evaluate their potential as feed probiotics. In addition, our B. subtilis expression system can serve as a cell factory for the microbial production of chemicals, enzymes and antimicrobial materials for use as feed additives.

Probiotic Bacillus Safety and Efficacy Assessment

  • Safety Assessment of Bacillus

Ensuring the safety of Bacillus strains as animal probiotics is essential. BioVenic provides solutions to assess the toxin production ability and antibiotic resistance of Bacillus. We offer full genome sequencing and analysis to detect genes responsible for enterotoxin production and the emetic toxin. Through ELISA and cell culture assays, we determine toxin production and cytotoxicity. Additionally, we examine phenotypic antimicrobial resistance and antimicrobial resistance genes to assess whether the strain exhibits intrinsic or acquired resistance to antibiotics such as vancomycin, gentamicin, kanamycin, streptomycin, erythromycin, clindamycin, tetracycline, and chloramphenicol.

  • In Vitro Efficacy Assessment of Bacillus as Feed Probiotics

We offer a variety of in vitro testing solutions for evaluating the suitability of Bacillus strains as probiotics for animals.

Our in vitro research solutions evaluate the tolerance of Bacillus spores and vegetative bodies to acid, bile salt, intestinal, and gastric fluids, providing information on their ability to survive, colonize, and persist in the gastrointestinal environment.

We provide solutions to measure the antimicrobial activity of Bacillus against Gram-positive bacterial pathogens, Gram-negative bacterial pathogens, and fungal pathogens.

We analyze enzymatic activities and characteristics of extracellular enzymes produced by Bacillus, such as amylase, protease, lipase, phytase, cellulase, and xylanase. We also offer solutions for developing enzyme additives from Bacillus.

  • In Vivo Probiotic Effect Study

To account for individual factors and determine the effects of probiotic supplementation, we conduct in vivo animal experiments using different species. We evaluate the safety and efficacy of Bacillus probiotics, considering growth performance, nutrient digestion and absorption capacity, intestinal health, and immune stimulation ability. These experiments help uncover the appropriate dosage, interactions with feed or other supplements, and the probiotic mechanisms of Bacillus specific to different animals.

Probiotic Bacillus Fermentation Solution

By carefully selecting the appropriate culture medium, optimizing the fermentation process, refining strains, and implementing stringent quality control measures, we offer viable solutions to support animal nutrition researchers in enhancing the probiotic Bacillus fermentation process. Our expertise spans small to large-scale production, helping increase probiotic yield and ensuring strain purity. In addition to Bacillus probiotics, our Bacillus fermentation techniques can yield enzymes, antibiotics, and other bioactive products.

Development of culture medium

We assist in adjusting the proportion of raw materials within the culture medium, taking into account their economic and nutritional value. This optimization promotes strain growth and vitality.

Optimization of fermentation process

We analyze the growth patterns of strains and the production of desired products to fine-tune critical factors such as pH levels, temperature, inoculation volume, and fermentation time. These optimizations maximize efficiency.

Quality control of
products

Leveraging our advanced detection technology platform, we meticulously screen fermentation products for harmful microorganisms and toxins. This comprehensive quality control process ensures the purity and safety of Bacillus probiotics, as well as any by-products generated in the fermentation process.
