Dairy & Food Ingredients

DVS Culture

Atri Biotech is a fully integrated biotechnology production house specializing in the manufacture of high-quality Lactobacillus spp. and Streptococcus spp. starter cultures for direct vat inoculation (DVI) of milk-based products. The company operates a state-of-the-art in-house fermentation and freeze-drying facility, enabling complete control over the entire production process.

The process begins with careful microbial strain development, selecting robust and high-performing Lactobacillus and Streptococcus strains suitable for dairy fermentation. These strains undergo optimized fermentation protocols, ensuring maximum growth, metabolic activity, and flavor development. Following fermentation, cultures are subjected to advanced freeze-drying technology, preserving cell viability, stability, and shelf life. Finally, the cultures are formulated under strict sterile conditions, ensuring purity and ready-to-use performance for DVI applications.

Atri Biotech has a production capacity of 1 MT per month each of Lactobacillus spp. and Streptococcus spp. cultures, tailored for yogurt, cheese, and other fermented milk products. By combining scientific expertise, scalable production, advanced freeze drying, and sterile formulation processes, the company delivers reliable, high performance starter cultures, supporting the Indian dairy sector with consistent quality, enhanced flavor, and efficient fermentation processes.

1. Microbial Strain Development

  • Selection of robust, high-performing Lactobacillus spp. and Streptococcus spp. strains.
  • Strains characterized for acidification rate, flavor profile, metabolic activity, and stress tolerance.
  • Continuous improvement through strain optimization and validation to meet dairy application requirements.

2. Fermentation & Optimization

  • Scaled-up cultivation in state-of-the-art in-house fermenters under controlled pH, temperature, and aeration.
  • Optimization of nutrient composition, growth kinetics, and fermentation parameters for maximum cell density and activity.
  • Real-time monitoring ensures consistent quality, metabolic activity, and flavor development.

3. Freeze-Drying (Lyophilization)

  • Harvested cultures concentrated and subjected to advanced freeze-drying technology.
  • Process preserves cell viability, enzymatic activity, and long-term stability.
  • Protectants and cryoprotectants used to maintain optimal survival and functionality during storage and transport.

4. Sterile Final Formulation

  • Freeze-dried cultures blended with carriers under strict sterile conditions to prevent contamination.
  • Packaged in ready-to-use form for direct vat inoculation (DVI) in yogurt, cheese, and fermented milk products.
  • Quality control ensures high purity, reproducibility, and consistent performance.

5. Production Capacity

  • 1 MT per month each of Lactobacillus spp. and Streptococcus spp. cultures.
  • Designed to meet the growing demand of the Indian dairy industry for reliable, high performance starter cultures.

Outcome:

High viability and stability, consistent fermentation, enhanced flavor development, and optimized dairy processing efficiency.

Citric Acid ( Monohydrate & Anhydrous)

Atri Industries is one of Maharashtra's leading supplier of industrial grade Citric Acid Monohydrate and Citric Acid Anhydrous that find extensive applications in various industrial processes. It replaces the use of strong inorganic, corrosive acids, heavy metal chelation, acidifier and descaling agent, for removal of lime scale from boilers and evaporators.

Its ability to chelate metals makes it useful in soaps and laundry detergents. By chelating the metals in hard water, it lets these cleaners produce foam and work more efficiently without the need for water softening. It can also be used in dissolving rust from steel.
