“…The remarkable scavenging activities with IC50 value 0.7 mg ml −1 were reported at corresponding concentrations. On day 13, retention of necrotic tissue, reduction in lesion sizes, neutrophilic inflammation, immaturity of the wound bed, erythema, edema, capillary, and increase in re‐epithelialization, hair follicle detection were reported in wounded rats which were previously exposed to this biosurfactant . Hence it can be a significantly used in the field of pharmacy and medicine.…”

Bioemulsifiers (BE) and biosurfactants (BS) are considered as multifunctional biomolecules of 21st century because of their functional abilities and eco‐friendly properties. They are produced by various microorganisms under versatile and extreme environmental conditions. They have tremendous applications in various industries such as petroleum, food, medicine, pharmaceutical, chemical, paper & pulp, textile, and cosmetics. Currently, they are also considered as “green molecules” because of their wide applications in bioremediation of soil. Their importance has been increasing day by day in the global market as they are the natural resources with high‐aggregate value. Although, there are numerous reports on BE and BS production by different bacteria, Acinetobacter spp. acquired special attention among all. This is because it is the earliest member known for the production of bioemulsifier. Emulsan and Alasan are the best examples of the commercially used BE produced by Acinetobacter spp. These BE are mainly used in microbial enhanced oil recovery and biodegradation of toxic compounds. This review is focused on BE and BS produced by Acinetobacter spp., their characterization and applications in different fields. This is the first review on genus Acinetobacter which defines independently about different types of BE and BS produced by it. It will also address the need of exploration of these molecules from various sources and their applications for the benefit of mankind and sustainable environment.

“…Biosurfactants are comparatively nontoxic and biodegradable products with unique properties such as superior foaming ability, high selectivity and active under adverse environmental conditions of pH, temperatures and salinity (Varjani and Upasani 2017). The microbial biosurfactants are amphipathic in nature with hydrophobic and hydrophilic regions that permit them to partition at the interface between immiscible liquid phases with diverse polarities such as oil and water (Ohadi et al 2017). Based on the origin and chemical nature, the biosurfactants are largely classified as lipopeptides, lipoproteins, glycolipids, phospholipids, fatty acids and polymeric molecules (Varjani and Upasani 2017).…”

A potential biosurfactant producing isolate was identified as Bacillus aryabhattai strain ZDY2. Biosurfactant production was enhanced by 2.51-fold through the development of an optimized process using response surface methodology. The optimized culture medium contained crude oil 4.0%, yeast extract 0.7% and NaNO 3 3.0% that yielded 8.86 g/l of biosurfactant. Biosurfactant was characterized for stability up to 100 °C, at pH 5-10 and in the presence of NaCl concentration up to 8%. Biosurfactant demonstrated antimicrobial activity against Salmonella typhimurium, Escherichia coli, Micrococcus luteus, Staphylococcus aureus and Candida tropicalis. The morphological characterization was carried out by scanning electron microscopy with energy-dispersive X-ray analysis. The Fourier-transform infrared spectroscopy analysis reveals the lipopeptide nature of the biosurfactant produced by B. aryabhattai strain ZDY2. The biosurfactant finds application in healthcare and pharmaceutical industries.

“…1 Biosurfactants comprise a wide variety of structurally distinct amphipathic molecules with potential applications in a wide range of biomedical fields, such as gene delivery, 7 antimicrobial, 8,9 anticancer, 10 and wound healing activities. [11][12][13] According to chemical structures, biosurfactants are categorized into two main groups; the lipopeptides and the glycolipids. 14 In nature, microemulsions formed using biosurfactant are thermodynamically stable and their isotropic systems are considered to be very promising in the development for DDS.…”

Background: Microemulsions drug delivery systems (MDDS) have been known to increase the bioavailability of hydrophobic drugs. The main challenge of the MDDS is the development of an effective and safe system for drug carriage and delivery. Biosurfactants are preferred surface-active molecules because of their lower toxicity and safe characteristics when compared to synthetic surfactants. Glycolipid and lipopeptide are the most common biosurfactants that were tested for MDDS. The main goal of the present systematic review was to estimate the available evidence on the role of biosurfactant in the development of MDDS. Search Strategy: Literature searches involved the main scientific databases and were focused on the period from 2005 until 2017. The Search filter composed of two items: "Biosurfactant" and/or "Microemulsion." Inclusion Criteria: Twenty-four studies evaluating the use of biosurfactant in MDDS were eligible for inclusion. Among these 14 were related to the use of glycolipid biosurfactants in the MDDS formulations, while four reported using lipopeptide biosurfactants and six other related review articles. Results: According to the output study parameters, biosurfactants acted as active stabilizers, hydrophilic or hydrophobic linkers and safety carriers in MDDS, and among them glycolipid biosurfactants had the most application in MDDS formulations. Conclusion: Synthetic surfactants could be replaced by biosurfactants as an effective biosource for MDDS due to their excellent self-assembling and emulsifying activity properties.
