Abstract:

Biosurfactants are a microbially synthesized alternative to synthetic surfactants, one of the most important bulk chemicals. Some yeast species are proven to be exceptional biosurfactant producers, while others are emerging producers. A set of factors affects the type, amount, and properties of the biosurfactant produced, as well as the environmental impact and costs of biosurfactant’s production. Exploring waste cooking oil as a substrate for biosurfactants’ production serves as an effective cost-cutting strategy, yet it has some limitations. This review explores the existing knowledge on uti

Abstract:

Surface-active agents or surfactants are amphiphilic compounds derived naturally or chemically synthesized. Natural surfactants or so-called biosurfactants can be obtained from bacteria, yeasts, and fungi as well as plants. Due to their hydrophilic and hydrophobic molecules, biosurfactants offer the ability to reduce surface or interfacial tension and create microemulsion between aqueous and organic phases. Many studies have suggested biosurfactants as a better substitution to chemical surfactants since they are more environment friendly, biocompatible, and has lower toxicity. This review arti

Abstract:

ABSTRACT Little is known about the interaction of biosurfactants with bacterial cells. Recent work in the area of biodegradation suggests that there are two mechanisms by which biosurfactants enhance the biodegradation of slightly soluble organic compounds. First, biosurfactants can solubilize hydrophobic compounds within micelle structures, effectively increasing the apparent aqueous solubility of the organic compound and its availability for uptake by a cell. Second, biosurfactants can cause the cell surface to become more hydrophobic, thereby increasing the association of the cell with the

Phytopathogenic fungi cause significant damage to agriculture, reducing or destroying the crop. There are several ways to control fungal diseases, such as the use of disease-resistant plant varieties, organic farming, and the use of fungicides. One of the methods of combating phytopathogens is the use of biological products, one of which is biosurfactants. Biosurfactants are surfactants produced in the course of life. They are able to reduce fungal growth and increase plant disease resistance, improve plant growth and yield, and act as adjuvants to improve wetting and solubility of fertilizers
