Basic functions of a Lab Fermenter | HOLVES The function of the Lab fermenter or else bioreactor is to provide an appropriate environment in which an organism can professionally produce a target product— the target product might be cell biomass, metabolite as well as bioconversion Product. It must be so intended that it is able to provide the most favorable environments or else conditions that will permit supporting the growth of the microorganisms. The design along with mode of operation of a fermenter mostly depends on the production organism, the finest operating condition requisite for target product formation, product worth as well as scale of production. The alternative of microorganisms is varied to be used in the fermentation studies. Bacteria, Unicellular fungi, Virus, Algal cells have all been cultured in Lab fermenter. Now more and more attempts are tried to grow single plant as well as animal cells in lab fermenters.
