“…In contrast, nunamycin production occurs on select agar-based media or in defined liquid minimal media supplemented with either glucose, glycerol and trehalose as carbon source ( Christiansen et al, 2020 ). Glycerol also supports viscosin production by P. antarctica and has been used as a carbon source for rhamnolipid production ( Zhao et al, 2021 ; Ciurko et al, 2023 ). Carbon source has been shown to influence tensin production in P. fluorescens , phytotoxin production in P. syringae and fungitoxin production in P. nunensis In5 ( Nielsen et al, 2000 ; Woo et al, 2002 ; Christiansen et al, 2020 ).…”

Lipopeptides (LPs) produced by Pseudomonas spp. are specialized metabolites with diverse structures and functions, including powerful biosurfactant and antimicrobial properties. Despite their enormous potential in environmental and industrial biotechnology, low yield and high production cost limit their practical use. While genome mining and functional genomics have identified a multitude of LP biosynthetic gene clusters, the regulatory mechanisms underlying their biosynthesis remain poorly understood. We propose that regulation holds the key to unlocking LP production in Pseudomonas for biotechnology. In this review, we summarize the structure and function of Pseudomonas-derived LPs and describe the molecular basis for their biosynthesis and regulation. We examine the global and specific regulator-driven mechanisms controlling LP synthesis including the influence of environmental signals. Understanding LP regulation is key to modulating production of these valuable compounds, both quantitatively and qualitatively, for industrial and environmental biotechnology.

“…Biosurfactants have such advantages as biodegradability, stability in a wide range of pH and temperatures, low toxicity, surface and emulsifying activity compared to their synthetic analogs [10]. In addition, the interest in utilizing inexpensive carbon sources (molasses, whey, vegetable oils, petroleum waste, etc.)…”

The article is dedicated to studying the ability of crude oil emulsification and displacement by bacteria producing low-molecular-weight biosurfactants. Six hydrocarbon-oxidizing cultures of microorganisms were used in this study: 3 strains of Pseudomonas aeruginosa (T1, T4, D2) and 3 Bacillus cultures: Bacillus licheniformis A3, Bacillus subtilis subsp. subtilis A12, Bacillus subtilis A9 from the collection of the Biotechnology Department of Al-Farabi Kazakh National University. The research findings indicate that cells of P. aeruginosa T1 exhibited maximum emulsifying and displacing properties, with an E24 value of 76.4% and an oil displacement ability of 5.1 cm. Among the three genes responsible for the production of low-molecular-weight biosurfactants, the presence of one gene, rhlA, responsible for the synthesis of rhamnolipid biosurfactants, has been confirmed. It was demonstrated that strains P. aeruginosa T1, P. aeruginosa T4, B. subtilis A9, and B. subtilis subsp. subtilis A12 showed high emulsifying activity, making them potentially effective for application in biotechnological processes aimed at enhancing oil recovery from mature reservoirs and in bioremediation processes.

“…Biosurfactants exhibit superior properties over synthetic ones in terms of biodegradability, surface activity, stability in a wide range of pH and temperature, low toxicity, and extraordinary emulsifying and demulsifying activity [3]. Due to these unique physicochemical properties, biosurfactants present potential applications in various fields, such as medicine, food, cosmetic and pharmaceutical industries, bioremediation, and agriculture sectors.…”
