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. |
