produce biomass or cell mass


Biomass produce biomass or cell mass The goal is to produce biomass or cell mass such as microbes, yeast, and fungi. Bulk commercial production has been seen in the production of bread yeast, which is used in the baking industry. Protozoan protein production (SCP) [1] is used as a protein-rich biosphere [6]. For example, an algae Spirulina [2] called, is used for animal feed in some countries. SCP protozoan protein is used as a food source from renewable sources such as whey, cellulose, starch, molasses and a wide range of plant residues.

Production of biological processes


Cell products

Products that are produced by cells and enzymes and metabolites are known as cellular products. These products are divided into intracellular and intracellular groups. Enzymes are one of the most important cellular products that are used in the industry. Enzymes are extracted from plants and animals. On the other hand, microbial enzymes can be produced in large quantities through conventional methods. The enzyme production capability can be improved by switching, selecting, or possibly genetically manipulating. The use of enzymes is very expensive in baking, cereal, coffee, candy, chocolate, corn syrup, dairy products, juices, and drinks. The most common enzymes used in the food industry are amylase in baking bread, protease, and amylase in beef production, pectinase [3] and hemicellulose [4] in coffee, lactase [5], Catalase [6] and protease in dairy products and glucose oxidase [7] in juice.

Modified compounds (bioconversion [8] )

Almost all major cell types can be used to convert a compound added to other compounds, used in various types of enzymatic reactions including dehydration, oxidation [9], hydroxylation [10], Mynvsyvn [11], isomerization [12] and so on Gets

These conversion species have advantages over chemical processes, in that the reaction can be very specific and produced at medium temperatures. Examples of conversion from enzymes include the production of steroids, the conversion of antibiotics and prostaglandins [13]. Converting industry to produce large amounts of enzymes needed but the half-life of inactivity and simple extraction of enzymes can be used by all cells, is improved.


In any biological process, the bioreactor is not a separate unit but acts as part of the integrated process with upstream and downstream components. The upstream sector includes storage tanks, units, and medium-organisms to multiply and prepare that sterilization [14] The following is taken. A primary culture for upstream inoculation is also required. In addition, sterilized materials (more sugar and nutrients)

Introduction to Industrial Microbiology

are essential for bioreactor operations. The bioreactor sterilization can be carried out by steam at lb f / in 2 (psi) 15, oC121 or any other chemical disinfectant such as ethylene oxide. The downstream process is involved with the extraction of the product and the purification of the waxes, such as conventional operating units, [7]. The solids are separated from the liquid, and the flotation solution may be removed from the separation unit for further purification after a thick product.
