The Photosynthetic Bacteria System (PSB), developed by IBAS Co., Ltd., helps aquaculture farms proactively manage water treatment and disease control.
Photosynthetic Bacteria (PSB) are bacteria capable of synthesizing food using sunlight. Unlike plants, algae, and cyanobacteria, they use hydrogen (H2), hydrogen sulfide (H2S), or sulfur (S) as electron donors. PSB differs from cyanobacteria as they lack chlorophyll to absorb light; instead, they contain bacteriochlorophyll with the ability to absorb shorter wavelength light. Therefore, they are found in deep water areas where short wavelength light can penetrate. They are also widespread in fields, ponds, lakes, rivers, seas, and soil, especially in organic-rich and polluted soil.
Common PSB species used in PSB products include Rhodopseudomonas palustris, Rhodobacter sphaeroid, Phodospririllum rubrum, and Thiobacillus sp. They help control toxic gases in aquaculture ponds, such as reducing ammonia (NH3), improving growth rates, significantly lowering Feed Conversion Ratios (FCR) by around 30%, purifying water quality, and increasing dissolved oxygen (DO) levels. PSB also serves as feed due to its high nutritional value, with protein content reaching about 60%, containing essential vitamins such as B-group vitamins, carotenoids, folate, and growth-promoting substances. Furthermore, PSB helps prevent and treat diseases by limiting the growth of disease-causing Vibrio bacteria, improving the appetite and digestion of aquatic organisms, and controlling excessive algae growth.
PSB controls toxic gases in aquaculture ponds
For many years, IBAS Co., Ltd. has researched the PSB production system, including PSB strain F1, cultivation medium, chlorine removal water supply system, three-tier rack system, infrared lamps, plastic containers, etc. PSB is exposed to infrared light to accelerate biomass production from F1 to F3. The environmental temperature, nutrition, and pH are optimized to shorten the biomass growth time, yielding volumes ranging from tens of thousands to millions of liters per month. PSB is used for various purposes, such as treating sulfides in wastewater, producing water treatment products for aquaculture, producing single-cell protein for livestock and aquatic animals, and manufacturing high-activity biological substances and bio-fertilizers.
On-site production systems will help large farms and businesses eliminate unnecessary intermediate steps and transportation costs. The system can be easily and conveniently installed anywhere, even on farms without ideal physical conditions. Having an on-site production system is particularly beneficial for farmers, as it allows them to control both water treatment and food production for shrimp and fish. This helps prevent diseases and reduce the need for antibiotic use.
The production system is introduced at the Technology Transfer Platform - 79 Truong Dinh Street, Ben Thanh Ward, District 1, Ho Chi Minh City.
