BIOSYNTHESIS OF SURFACTANTS ON INDUSTRIAL WASTE

Abstract

The literature and own experimental data on the synthesis of microbial surfactants of different chemical nature (rhamnolipids, sophorolipids, manozylerythritollipids, lipopeptides) at various waste (vegetable oil and fat, sugar, dairy industry, agriculture, forestry, biodiesel, as well as waste — fried vegetable oils) are presented. Most suitable substrates for the synthesis of microbial surfactants are oil containing waste that, unlike, for example, lignocellulose, whey, technical glycerol do not require pre-treatment and purification. Replacing traditional substrates for the biosynthesis of surfactant with industrial waste will help to reduce the cost of technology by several times, dispose of unwanted waste, solve the problem of storage or disposal of large amounts of waste from the food industry, agricultural sector and companies that produce biodiesel, which spent large amount of energy and money for such needs
