Lipopeptides from Bacillus methylotrophicus DCS1 are endowed with interesting properties. The composition of production medium and culture conditions were optimized by studying the effect of 14 variables in a 23 run Plackett-Burman design (PBD) to screen for key factors with the aim of improving lipopeptides yield and surface activity with low production costs. In PBD, four significant factors (Urea, CaCl2, gruel and temperature) affecting the production, were choosed for further optimization and constructed via Box-Behnken design (BBD). Enhanced lipopeptides production was carried out using gruel as carbon source at a concentration of 40 g L -1 and urea as nitrogen source at a concentration of 5.5 g L -1 . The optimal conditions were 33 °C temperature, pH 7.5, an agitation of 175 rpm and 2.5% inoculum size. Utilizing the predicted optimized conditions, the maximum lipopeptides yield of 4.7 g L -1 was reached which accord well with the predicted value.

“…Optimization approaches, such as statistical experiment design, may then be applied. The choice of production method is contingent upon various aspects, including the particular biosurfactant of interest, the microbe employed, the size of production, and the needs of the application ( Vigneshwaran et al, 2021 ). Each method has pros and cons.…”

The adverse effects of waste generation on the environment and public health have raised global concerns. The utilization of waste as a raw material to develop products with enhanced value has opened up novel prospects for promoting environmental sustainability. Biosurfactants obtained from agro-industrial waste are noteworthy due to their sustainability and environmental friendliness. Microorganisms have been employed to generate biosurfactants as secondary metabolites by making use of waste streams. The utilization of garbage as a substrate significantly reduces the expenses associated with the process. Furthermore, apart from reducing waste and offering alternatives to artificial surfactants, they are extensively employed in bioremediation, food processing, agriculture, and various other industrial pursuits. Bioremediation of heavy metals and other metallic pollutants mitigated through the use of bacteria that produce biosurfactants which has been the more recent research area with the aim of improving its quality and environmental safety. Moreover, the production of biosurfactants utilizing agricultural waste as a raw material aligns with the principles of waste minimization, environmental sustainability, and the circular economy. This review primarily focuses on the production process and various types of biosurfactants obtained from waste biomass and feedstocks. The subsequent discourse entails the production of biosurfactants derived from various waste streams, specifically agro-industrial waste.

The demand for biosurfactants (BS) produced by yeast for use in industrial processes and products is increasing. Therefore, there has been an increase in the number of publications related to characterization of surfactant compounds produced by yeasts generally recognized as safe (GRAS), which has enabled their application in several industries, including the pharmaceutical and food industries. However, some of these studies use techniques that are not accurate or are no longer essential because of advancements in new technologies. Given the industrial importance of yeasts and their potential to produce BS, this study reviews the production of BS by this microorganism and the most recent industrial applications of BS. It also critically reviews a wide range of techniques used in screening of BS-producing strains, as well as those used in recovery, purification, and characterization of these surfactant compounds produced by yeasts. This review introduces diverse methodologies that are indispensable for the study of BS produced by yeast in an effort to advance BS design, synthesis, and application and introduces new perspectives in the research of these compounds to overcome the obstacles present in this field.
