Individual cells function as a collection of interacting biochemical molecules and molecular machines. Consider single-cell microbes, the simplest self sufficient living organisms. At a macroscopic level they are a small bag of biochemical cytoplasm with little internal structure. Yet microbes create and use the fundamental molecular machinery common to all life (protein synthesis via DNA transcription and ribosomal mRNA translation,regulation of gene expression, membrane control of small molecule transport, signal propagation)to sense the state of their environment and respond appropriately (grow, move, reproduce).Eukaryotic cells execute enhanced versions of these regulatory, metabolic, and signaling networks within structures of rich spatial complexity (organelles, membranes, filaments, etc).Such a picture poses a wide range of challenges for computational cell modeling in which various groups are addressing in different ways. Typically, one key input to all such models is a set of reaction rate equations which specify the biochemistry to be modeled. Each equation has one or more reactants which are converted at a certain rate into one or more products.Complex networks may contain 100s or 1000s of such coupled equations.

Water Treatment Microbiocide is a synergistic blend of glutaraldehyde and quaternary ammonium salt which is specially formulated to provide a surface-active product that can clean and penetrate microbiologically-fouled surfaces. It is effective in controlling slime-forming and sulfate-reducing bacteria and algae. The ease of handling and high potency of Water Treatment Microbiocide facilitate its use in recirculating cooling towers, air washer systems, recirculating process water and closed loop cooling systems. It kills microbes such as bacteria, viruses, and fungi and used in disinfectant or antibacterial products.

A culture medium is any nutrient liquid or solid that can be used in the laboratory & for the growth of micro organisms. Such a medium may resemble a natural substrate on which the micro organism will usually grow like blood serum for animal pathogen milk for milk micro organism. Distilled water is used to dissolve all to medium components. Peptones are used as a nitrogen source & it has another function in the medium that is buffering material, because it is an amphoteric compound it can maintain the medium PH Carbohydrates, peptides, amino acid and proteins are used as an energy source. Usually beef extract is used as a growth factor. Gelatin or agar agar is used as a solidifying agent. Media can be classified based on texture as liquid media, solid media, reversible to liquid, semi solid media. Selective media is used to isolate one species of micro organism and inhibit the growth of another micro organism. Differential media-in which we add a natural or chemical compounds differentiate microbial groups which may be formed in the same culture. Enriched media-in which we need to add blood serum or plant tissues to enrich the growth of specific groups of micro organism like heterophilic bacteria.
