Summary: Biosurfactants are amphipathic molecules that can lower interfacial and superficial tensions. They are biodegradable and have a wide diversity of categories, with lipopeptides being the most abundant and well-known. Protein-containing biosurfactants are less studied but could be a valuable alternative. Understanding the harsh conditions that target organisms can sustain is crucial for successful implementation. This article explores the biotechnological applications of lipopeptide and protein-containing biosurfactants, as well as their natural role and the potential research possibilities using meta-omics and machine learning.

Summary: The study focused on the application of biosurfactants for degrading toxic compounds, specifically 4-ABP, and found that biosurfactant-mediated processes can replace chemical surfactants, with the biosurfactant produced being a lipopeptide. Molecular and instrumental analysis revealed the presence of fatty acids in the produced biosurfactant, with GC-MS analysis showing the presence of other metabolites in the degraded products.

Summary: Bacillus subtilis 3NA, a strain capable of high cell densities, utilized its surfactin-producing variant JABs32 in fed-batch processes to achieve significantly increased surfactin titers. Optimization of culture conditions showed a promising potential for enhanced surfactin production in high cell density fermentation.

Summary: Surfactin, a lipoheptapeptide produced by several Bacillus species, has a complex biosynthesis process with diversity in peptide and fatty acid side, leading to a wide range of physico-chemical properties and biological activities. Recent studies focus on metabolic modeling, engineering, and synthetic biology to enhance surfactin production and generate novel derivatives. Optimization of production processes in Bacillus cells considers different steps from gene transcription to surfactin degradation in culture medium.

Summary: This research aimed to optimize the production of a lipopeptide biosurfactant from Bacillus sp. SHA302 for efficient release of heavy metals in soil. The results showed that the metal release capacity of the biosurfactant increased with its concentration, and the highest release rates for Zn and Pb were achieved in the critical micelle concentration (CMC) + HCl treatment. A factorial experiment and response surface methodology were used to optimize biosurfactant production, and factors such as pH, ammonium chloride, magnesium sulfate, and sugar beet molasses significantly affected biosurfactant production and surface tension reduction. The optimized conditions resulted in the highest biosurfactant production and lowest surface tension.

Summary: Marine sponge-associated bacteria are well-known producers of bioactive compounds, but little progress has been made in the investigation of biosurfactants produced by these bacteria. This review compiles the current knowledge on biosurfactants from sponge-associated bacteria, with a focus on their biotechnological applications. Lipopeptides and glycolipids were found to be the most identified chemical classes of biosurfactants.

Summary: Surfactin, a biosurfactant produced by Bacillus subtilis, exhibits high interfacial activity and emulsion forming properties, making it a strong candidate for O/W emulsification. It is stable within the pH range of 6 to 9, but destabilizes with CaCl2 addition (>3mM).

Summary: The microbial conversion of agro-industrial oil wastes into biosurfactants using Bacillus subtilis #309 shows promise as a biomass refinery approach. Surfactin production using rapeseed and sunflower cakes was analyzed, and the surfactin concentration, pH, surface tension, and emulsification index were measured. The surfactin concentration reached 1.19 +/- 0.03 g/L in sunflower cake medium and 1.45 +/- 0.09 g/L in rapeseed cake medium. The surfactin exhibited antioxidant activity and significant angiotensin-converting enzyme (ACE)-inhibitory activity. The ACE-inhibitory lipopeptide biosurfactant shows promise to be used as a natural antihypertensive agent.

Summary: This study aimed to produce biosurfactant and investigate the synergistic action on decolourisation of textile dyes by the combination of bacteria and biosurfactant. The results showed that the synergistic activity of Kurthia gibsonii KH2 and lipopeptide biosurfactant resulted in decolourisation levels of 85% at 100 mg/L concentration and pH 7 was recorded at 168 h of incubation. The high attributes of these combinations and the phytotoxicity tests implied that the metabolites were less toxic, making it a promising option for the biodecolourisation and biodegradation of industrial textile wastewater and various environmental conditions.

Summary: Microbial enhanced oil recovery (MEOR) is an important method that utilizes microbes and their products to recover crude oil from reservoirs, with biosurfactants playing a crucial role due to their optimal interfacial properties. An optimized biosurfactant produced by Bacillus licheniformis L20 has been characterized as a series of lipopeptides, and has demonstrated promising potential for ex-situ MEOR in harsh reservoir conditions through wettability alteration and core flooding experiments.
