Agar is a polysaccharide complex extracted by bleaching and hot water treatment of agarocytes from the red alga Rhodophyceae, and usually consisting of the genera Gelidium, Acanthopeltis, Ceramium, Pterocladia and Gracilaria. The algae are typically found in the Pacific and Indian Oceans and in the Sea of Japan. It is primarily composed of two different units: Agarose and Agaropectin; Agarose is a neutral gelling component which is composed of a linear polymer of alternating D-galactose and 3,6-anhydrogalactose units. Agaropectin is a non-gelling component which consists of D-1,3-glycosidically linked D-galactose units, some of which are sulfated at the 6th position.
Agar is typically used in (According to the Merck Index): Substitute for gelatin, isinglass, etc. in making emulsions including photographic, gels in cosmetics, and as thickening agent in foods especially confectionaries and dairy products; in meat canning; in production of medicinal encapsulations and ointments; as dental impression mold base; as corrosion inhibitor; sizing for silks and paper; in the dyeing and printing of fabrics and textiles; in adhesives.

5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside, commonly known as X−Gal, is a histochemical substrate for β−galactosidase.
5-Bromo-4-Chloro-3-Indolyl-β-D-Galactopyranoside is used as indigogenic substrate for β-galactosidase, for detection of β-galactosidase-positive clones, and the identification of lac and bacterial colonies or phage plaques. It is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype. X−Gal is cleaved by β−galactosidase to yield an insoluble blue precipitate. X−Gal is particularly useful in molecular biology applications to detect the activity of β−galactosidase which is frequently used as a reporter gene. In cloning, X−Gal is used to detect insertion of foreign DNA into the lacZ region of plasmid DNA using α-complementation which is based on vectors such as the pUC and the M13mp series that carry a fragment of the β-galactosidase gene encoding an α-fragment of β-galactosidase.

Cefotaxime is a cephalosporin, which acts by interference of synthesis of peptidoglycan of the bacterial cell wall. Cefotaxime, a cephalosporin antibiotic, is active against both gram-negative and gram-positive bacteria. In addition, cefotaxime blocks the division of cyanobacteria and lower plant organelles/plastids such as the photosynthetic organelles of Glaucophytes and chloroplasts of bryophytes.
Cefotaxime is used for infections of the respiratory tract, skin, bones, joints, urogenital system, meninges, and bloodstream. It generally has good coverage against most Gram-negative bacteria, with the notable exception of Pseudomonas. It is also effective against most Gram-positive cocci except for Enterococcus. It is active against penicillin-resistant strains of Streptococcus pneumoniae. It has modest activity against the anaerobic Bacteroides fragilis. In meningitis, cefotaxime crosses the blood–brain barrier better than cefuroxime.
Cefotaxim inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) which inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls. As a result, bacteria lyse due to cell wall autolytic enzymes.

Pyruvic acid is an intermediate in sugar metabolism and in enzymatic carbohydrate degradation (alcoholic fermentation) where it is converted to acetaldehyde and CO2 by carboxylase. In muscle, pyruvic acid (derived from glycogen) is reduced to lactic acid during exertion, which is reoxidized and partially retransformed to glycogen during rest. It improves coliform recovery when present in culture medium. It is involved in a metabolic regulatory pathway activated by mitochondrial oxidants. Pyruvate is involved in respiratory regulation in plants by interacting with alternative oxidase at a conserved cysteine residue. It may help prevent hydrogen peroxide mediated cell death.
Sodium pyruvate is utilized as a component in culture broth and media. Sodium pyruvate is used in Wallen fermentation medium to enhance the conversion of oleic acid to 10-ketostearic acid by Bacillus sphaericus. Sodium pyruvate has also been used to establish stably transfected human B cell lines.
Sodium Pyruvate has shown antioxidant properties and protective effects against oxygen radicals. Pyruvate is produced as part of glycolysis and is an intermediate in many metabolic pathways. It can be converted into acetyl CoA and enter the TCA Cycle.
