Biofloc Bacteria

This is a major bottleneck of microalgal technology. Probiotics are beneficial bacteria which play an important role in the microbial balance of the microbiome and the water environment.

Biofloc Technology In Aquaculture Aquaculture Technology Infectious Disease

The beneficial bacteria in the biofloc are located on the surface of the floc in the thin but convoluted biofilm.

Biofloc bacteria. Bacteria are very small. In an established filter media 999 of the ammonia oxidation is done in a thin biofilm which is on top of a brown biofloc. Luckily when we have a dense culture They tend to form bioflocs containing bacteria other organisms and organic particles.

Biofloc is a collection flocs of algae bacteria protozoans and other kinds of particulate organic matter such as faeces and uneaten feed. The function of the biofloc is to reduce the nitrogenous metabolic waste ammonia nitrite produced by shrimp feeding and production.

The major component of biofloc is heterotrophic bacteria. Phytoplankton heterotrophic and nitrifying bacteria have the most important role in biofloc while fungi ciliate protozoa rotifer copepod and nematode complement the biofloc community by participating in the food web that includes the cultured animal too. Biofloc system has some microorganisms such as heterotrophic bacteria algae fungi nematodes metazoans and detritus that conglomerate together and also perform symbiotic processes to keep the water quality support a high density of fish culture and reduce water exchange in the aquaculture system.

Microorganisms play a major role in biofloc technology. In biofloc system the heterotrophic bacteria colonize the feces molts dead organisms and unconsumed food to produce bacterial biomass which is consumed by detritivores 8. The function of the Biofloc system is to reduce the nitrogenous metabolic waste ammonia nitrite produced by shrimp feeding and production.

The presence of beneficial bacteria in the biofloc creates a natural probiotic effect which can act both internally and externally to combat pathogens and improve immune response. Ammonia consumed by heterotrophic bacteria becomes protein which can then be consumed by shrimp and converted into growth. In other words biofloc is a symbiotic process that includes confined aquatic animals heterotrophic bacteria and other.

The function of the biofloc is to reduce the nitrogenous metabolic waste ammonia nitrite produced by shrimp feeding and production. Bioflocculation of microalgae and bacteria addresses this. Biofloc or Raceway system maintains a sufficient amount of carbohydrates.

Biofloc consists of microorganisms such as heterotrophic bacteria algae dinoflagellates and diatoms fungi ciliates flagellates rotifers nematodes metazoans and detritus that conglomerate together and perform symbiotic processes to maintain the water quality maintain bio-security support high density of shrimp culture and reduce water exchange in the aquaculture system. Form the Bioflocs Proteobacteria Bacteroidetes Bacillus spp. Carbon present in these carbohydrates promotes heterotrophic bacteria to multiply and synthesize ammonia so maintain the water quality parameters.

Imhoff cone showing biofloc settled Floc level will increase with the growth of heterotrophic bacteria Heterotrophic bacteria Bacillus spp. The major component of biofloc is heterotrophic bacteria. This is a major improvement for microalgal technology for wastewater treatment.

The Biofloc in the shrimp-rearing tank must be considered a dynamic living organism and must be managed as such. How to maintain floc in Biofloc fish farming. Each floc is held together in a loose matrix of mucus that is secreted by bacteria bound by the filamentous microorganism or held by electrostatic attraction.

Ammonia consumed by heterotrophic bacteria becomes protein which can then be consumed by shrimp and converted into growth. Ammonia produced from the nitrogenous feed as a metabolic product pollutes the water quality. The main component of Biofloc is heterotrophic bacteria.

MaB-flocs or M icro a lgal B acterial flocs settle by gravity up to density of 20 g per liter. Biofloc technology BT is defined as the use of aggregates of bacteria algae or protozoa held together in a matrix along with particulate organic matter for the purpose of improving water quality waste treatment and disease prevention in intensive aquaculture systems.
