Microbial production of surfactants and their commercial potential
Article Abstract:
Biosurfactants are structurally diverse group of surface-active molecules produced by microorganisms, which have been found to have the capacity to reduce surface and interfacial tensions in both aqueous solutions and hydrocarbon mixtures. Among its promising applications are oil spill management, transportation of heavy crude oil and bioremediation of sites contaminated with hydrocarbons, heavy metals and other pollutants. Microbial production of biosurfactants depends on several factors such as microbial strain, source of carbon and nitrogen and hydrogen-ion concentration.

Oral microbial ecology and the role of salivary immunoglobulin A
Article Abstract:
The indigenous microbiota is important to the development of the immune system. Indigenous bacterial in the oral cavity are often linked to the etiology of two major oral diseases. The ecology of the oral cavity is discussed, and the factors responsible for the transition of the oral microbiota to a pathogenic relationship with the host, from a commensal one, are considered. Secretory immunoglobulin A (SigA) is a prominent isotype in secretions and is the first line of defense against pathogens.

P(sub)II signal transduction proteins, pivotal players in microbial nitrogen control
Article Abstract:
The signal transduction protein P(sub)II is one of the conserved bacterial signal proteins that plays a significant role in coordinating nitrogen metabolism in bacteria. The review discusses specific data on the structure-functional aspects of the protein and their role in the acquisition, catabolism, and assimilation of nitrogen compounds.
