Increasing public awareness of environmental pollution influences the search and development of technologies that help in clean up of organic and inorganic contaminants such as hydrocarbons and metals. An alternative and eco-friendly method of remediation technology of environments contaminated with these pollutants is the use of biosurfactants and biosurfactant-producing microorganisms. The diversity of biosurfactants makes them an attractive group of compounds for potential use in a wide variety of industrial and biotechnological applications. The purpose of this review is to provide a comprehensive overview of advances in the applications of biosurfactants and biosurfactant-producing microorganisms in hydrocarbon and metal remediation technologies.

Orthodontic fixed appliance therapy is the commonest
mode of treatment for most types of malocclusions (teeth irregularities).
However, these materials are liable for microbial adhesion, which predisposes
the wearer to increased microbial burden. The present study aims to
evaluate, microbial adhesion and growth on commonly used orthodontic ligating
materials (Teflon coated wire, stainless steel wire, elastic rings)
under in vitro condition. Furthermore, the role of saliva on adhesion
and microbial colonization on said materials was also assessed. Experiments were
conducted with three different orthodontic ligating materials each in 6
numbers. Growth OD, metabolic activity and cell viability were the experimental
variables in addition to SEM (Scanning Electron Microscopy) analysis performed.
Results revealed irespective of the nature of the ligating materials,
microbial adhesion and growth were observed in all the materials and suggested
that the chosen materials promotes microbial adhesion. Nevertheless, stainless
steel ligatures were less prone to adhesion compared to Teflon coated and
elastic ligatures. Presence of saliva accelerates adhesion and growth.
