“…Therefore, it has potential for future remediation. Suryanti et al (2016) examined the production of a glycolipid biosurfactant by Rhodococcus rhodochrous for remediation of cadmium. The biosurfactant had a CMC of 896 mg/L and could stabilize an emulsion up to 12 days.…”

Selection of the most appropriate remediation technology must coincide with the environmental characteristics of the site. The risk to human health and the environment at the site must be reduced, and not be transferred to another site. Biosurfactants have the potential as remediation agents due to their biodegradability, low toxicity, and effectiveness. Selection of biosurfactants should be based on pollutant characteristics and properties, treatment capacity, costs, regulatory requirements, and time constraints. Moreover, understanding of the mechanisms of interaction between biosurfactants and contaminants can assist in selection of the appropriate biosurfactants for sustainable remediation. Enhanced sustainability of the remediation process by biosurfactants can be achieved through the use of renewable or waste substrates, in situ production of biosurfactants, and greener production and recovery processes for biosurfactants. Future research needs are identified.

Textile industries monopolize the use of synthetic and natural colors, claiming they are safe for the environment. These dyes have disastrous repercussions when released into the terrestrial and aquatic environment. The main purpose of the study was to isolate a biosurfactant‐producing bacterium from textile effluent‐contaminated soil and study its potential for dye degradation. Biosurfactant was extracted from Rhodococcus ruber strain TES III, a bacterium isolated from textile water contaminated soil. This biosurfactant‐producing bacterium was capable of decolorizing both synthetic dyes like methyl orange, methylene blue, and natural dyes like Indigo. There was a 2‐fold increase in methyl orange degradation after 48 hours, a 1‐fold increase in methylene blue degradation, and a 4.13‐fold increase in indigo dye degradation. Based on the foregoing data, we conclude that the biosurfactant‐producing bacteria Rhodococcus ruber strain TES III has a high potential for dye degradation and hence can be used in wastewater treatment of textile industries.

“…The optimization of biosurfactant production was conducted according to our previous works (Suryanti et al 2016a;Suryanti et al 2016b). Lactobacillus lactis was grown in a 200 mL fermentation medium with and without the addition of CPO and incubated for 12 days.…”

Biosurfactants are surface-active compounds produced by a wide variety of diverse microorganisms. The structural diversity of biosurfactants depends on microorganisms and growth conditions (such as substrate and pH). The unique structure of biosurfactants provides unique properties for specific applications. Biosurfactant production still needs to be explored using a variety of microorganisms and growth conditions for producing the diversity of biosurfactant structures. Production and characterization of biosurfactant by Lactobacillus lactis using Crude Palm Oil (CPO) as an additional carbon source has been conducted. The optimization condition of biosurfactant production by L. lactis using media containing various concentrations of CPO was evaluated. Optical density, surface tension, and emulsification index were observed daily for 12 days. Optimal biosurfactant production condition was achieved when L. lactis was grown on media Nutrient Broth containing 10% (v/v) of CPO and incubated for 8 days. Biosurfactants were obtained for 80 mg/L media. Based on Thin Layer Chromatography (TLC) analysis and Fourier Transform Infra-Red (FT-IR) Spectroscopy, produced biosurfactant was identified as a glycolipid biosurfactant containing functional groups of hydroxyl, ester, carboxylic, methyl, and methylene. Produced biosurfactants exhibited the Critical Micelle Concentration (CMC) value of 1 g/L with a surface tension value of 49.46 mN/m. The emulsion system of produced biosurfactant was water in oil (w/o). The produced biosurfactant showed an emulsification index of 41-71% with soybean oil, palm oil, sunflower oil, olive oil, and lubricant oil. The stable emulsion was reached up to 30 days when soybean oil, olive oil, and lubricant oil were used as the water-immiscible compound.
