Optimization and production of a biosurfactant from the sponge-associated marine fungus Aspergillus ustus MSF3

Due to the toxicity of petroleum compounds, the increasing accidents of marine oil spills/leakages have had a significant impact on our environment. Recently, different remedial techniques for the treatment of marine petroleum pollution have been proposed, such as bioremediation, controlled burning, skimming, and solidifying. (Hedlund and Staley in Int J Syst Evol Microbiol 51: [61][62][63][64][65][66] 2001). This review introduces an important remedial method for marine oil pollution treatment-bioremediation technique-which is considered as a reliable, efficient, cost-effective, and eco-friendly method. First, the necessity of bioremediation for marine oil pollution was discussed. Second, this paper discussed the species of oil-degrading microorganisms, degradation pathways and mechanisms, the degradation rate and reaction model, and the factors affecting the degradation. Last, several suggestions for the further research in the field of marine oil spill bioremediation were proposed.

“…SPMS3 was chosen for further characterization studies. Many researchers have been previously reported about the significance of multiple screening tests for the isolation of most potential biosurfactant producers and chosen methods were standard techniques for the effective isolation of biosurfactant producer (Mani et al, 2016a;Khopade et al 2012;Kiran et al 2009). Similarly, Walter et al, 2010 described that the combination of different methods is appropriate for a successful screening of biosurfactant producing bacteria.…”

“…All the fermentations were carried out using 30ml crew cap tubes with 10ml working volume and were incubated in a rotary incubator at 30ºC for 7days. The centrifuged supernatants of the cultured broth were screened for the most potential biosurfactant producer using the following multiple screening methods includes emulsification activity (Cooper and Goldenberg, 1987), lipase activity (Kiran et al, 2009) and oil displacement test (Youssef et al, 2004). Based on the promising results from these screening methods, the potential strain was selected and further studies were carried out using the potential bacterium.…”

A potential biosurfactant producing halophilic bacterium was isolated from the saltpan environment of Porto Novo, Tamilnadu, India. The potential bacterium showed 69.9 % emulsification activity, 56.7 units/ml lipase activity and 22 mm oil displacement in the biosurfactant multiple screening methods. This halophilic bacterium was identified as Bacillus species using 16S rRNA molecular sequencing method. This strain showed growth dependent biosurfactant production, which was partially purified and weighed at 0.945 ±0.021 g/L on dry weight basis. The isolated biosurfactant was biochemically identified as glycolipid using biochemical methods and FT-IR functional group analysis. Further, the glycolipid surfactant showed consistent oil recovery efficiency than the tested synthetic surfactant at the temperature up to 50°C and pH ranged from 5 to 8. Based on these observations, the isolated biosurfactant using this halophilic bacterium revealed promising microbially enhanced oil recovery and bioremediation purposes at a wide range of environmental conditions.

Abstract-To enhance lipopetide biosurfactant production by Pseudomonas spp., the effects of medium and culture conditions were investigated. Nutrient broth (NB) supplemented with glucose and molasses as carbon sources were used to increase biosurfactant yield. Cultivation temperatures and initial pH were also studied. In this experiment, NB was used as a control to produce biosurfactant with the yield of 0.58 g/L. The lipopeptide biosurfactant yield was increased to 2.76 g/L when Pseudomonas spp. was cultured in NB supplemented with 1% w/v glucose, 500 µM FeSO4, pH 9.0 and cultivation of 20°C for 72 h. Its specific growth rate was 0.25 h-1.Index Terms-Pseudomonas spp., lipopeptide biosurfactant, glucose, ferrous.
