Bacteria are ubiquitous in nature. Based on their role bacteria may be grouped as beneficial, spoilage causing and pathogens. The saprophytic group, involved in causing the spoilage of milk and milk products, produce various kinds of surfactants to utilize the milk components. Synthetic surfactants dominate in the market especially in detergent formulations and considered as non-biodegradable and toxic. Biosurfactants are surface metabolites produced by bacteria and fungi having very different chemical structures and properties.

Most Bacillus species have ability to produce secondary metabolites such as amylases and biosurfactants. This study was carried out to determine the amylase and boisurfactant production potentials of some Bacillus species obtained from agricultural soil. Soil samples were collected from agricultural research farm of Adekunle Ajasin University, Akungba-Akoko, Ondo State, Nigeria. All isolates were identified based on the morphological and biochemical characteristics using Bergey’s manual of determinative bacteriology.

In recent times river pollution is a serious and growing problem in most developing countries. Industrial effluents and sewage entering the water bodies are one of the major sources of environmental toxicity, which endangers aquatic biota and deteriorates water quality. Biological methods for the removal of heavy metals from industrial waste may provide an attractive alternative to the physiochemical process. Biosurfactants are one of the compounds that help in alleviating the heavy metals.

Biosurfactants are surface active compounds released by microorganisms. There are several known microbe involve for the production of biosurfactants but exploration of potential biosurfactant producer is need of hours to accelerate its economic production for industrial use. These compounds are mainly classified according to their molecular weight, physico-chemical properties and mode of action. They are eco-friendly, easily biodegradable and non-toxic materials.

Sophorolipid (SL) is a biosurfactant belonging to the glycolipids group and was produced by harmless Candida bombicola ACTT22214 and has been widely used in many fields in our life. In order to search for appropriate condition for C. bombicola fermentation producing SL with high efficiency, this study focused on the investigation of the soy oil concentration, molasses concentration, fermentation time, pH and temperature. SL products were tested for antimicrobial activity, antioxidant, emulsifier, foaming ability. The highest content of SL was 43.27 ± 0.

Toothpaste is a gel dentifrice used with a toothbrush as an accessory to clean, keep and promote oral hygiene. The literature review suggests that there are many different formulations of toothpastes and that each of their individual components present specific functions. The concentration of the toothpaste ingredients must be appropriately chosen taking into account the purposes of the toothpaste. Biosurfactants are considered as suitable molecules for application in many formulations such as in toothpaste one.

Biosurfactants are surface active molecules that are produced by microorganisms. Their positive features attract the attention of many researchers compared to their chemically synthesized counterparts. This research studied the production of a biosurfactant by Pleurotus ostreatus in submerged fermentation (SmF) and solid-state fermentation (SSF), with and without shaking.

The sulphate-reducing bacteria (SRB) isolated from Bach Ho oil well (H strain), Thi Nai pond sediments in Quy Nhon (6C) was used to evaluate the degradability of crude oil and oil products. The oil samples were treated by specific strains and their combination. It was shown that after 3 to 7 weeks of treatment these strains degraded up to 36 - 57% of residual oil, 7 - 12% of crude oil and 19 - 21% of fuel oil (FO) in the medium. The oil degradability of all samples increased 3 - 12% in the present of biosurfactants compared to the case without adding biosurfactants.

Lipases find promising applications in organic chemical processing, detergent formula- tions, synthesis of biosurfactants, the oleochemical industry, the dairy industry, the agro- chemical industry, paper manufacture, nutrition, cosmetics, and pharmaceutical processing. Development of lipase-based technologies for the synthesis of novel compounds is rapidly expanding the uses of these enzymes (Liese et al., 2000). One limiting factor is a shortage of lipases having the specific required processing characteristics.
