Streptococcus pyogenes

Streptococcus pyogenes is a Gram-positive bacterium that causes several diseases in humans, including pharyngitis, skin infections, acute rheumatic fever, scarlet fever, poststreptococcal glomerulonephritis, a toxic shock–like syndrome, and necrotizing fasciitis.

Neisseria gonorrhoeae for more details - Neisseria meningitidis Neisseria  is a large genus of  bacteria  that colonize the  mucosal surfaces of many animals. Of the 11 species that colonize humans, only two are  pathogens ,  N. meningitidis and  N. gonorrhoeae . Most gonoccocal infections are asymptomatic and self-resolving, and epidemic strains of the meningococcus may be carried in >95% of a population where  systemic disease  occurs at <1% prevalence. Neisseria  species are  Gram-negative bacteria included among the  proteobacteria , a large group of Gram-negative forms.  Neisseria diplococci  resemble  coffee beans when viewed microscopically.

Industrial Microbiology  Scope of Industrial Microbiology. Microorganisms of industrial importance. Fermentation processes including culture methods – solid and submerged. Strain selection and development, media formulation and economics. Optimization of the fermentation process including fermentation design, fermenters and operations. Primary and secondary metabolites. Microbiological quality control of foods, drugs and cosmetics. Use of enzymes in the industries  Industrial Microorganisms and Their Products The major organisms used in industrial microbiology are fungi (yeasts and molds) and certain prokaryotes, in particular species of the genus Streptomyces. Industrial microorganisms can be thought of as metabolic specialists, capable of synthesizing one or more products in high yield. Industrial microbiologists often use classical genetic methods to select high-yielding microbial variants, with the goal being to increase the yield of the product to the point that
