“…The result agreed with other reports [15]. For P. aeruginosa KVD-HR42, the biosurfactant production was raised by cultivation at pH 8.5 [3]. The optimal pH for extracellular biosurfactant produced by Yarrowia lipolytica NCIM 3589 was 8.0 [16].…”

“…The lipopeptide biosurfactant yield of Bacillus subtilis B20 was increased to 2.29 g/L when cultured with molasses [5]. Karanja oil was also able to increase the biosurfactant yield of Pseudomonas aeruginosa KVD-HR42 to 5.90 g/L [3].…”

“…The biosurfactant yield from Pseudomonas sp. was increased after cultivation with optimal pH and temperature [3]. Moreover, Hemtala et al [8] reported that culture temperature and pH was also the factor to enhance biosurfactant yield from Stenotrophomonas maltophilia NBS-11.…”

“…Biosurfactants are produced by many living organisms, especially microorganisms. They are classified into 4 groups based on their chemical structures; glycolipids, lipopeptides, phospholipids and fatty acids, and polymeric biosurfactants [3]. In addition, biosurfactants exhibit important properties such as antimicrobial activity, anti-adhesion of microorganisms, biodegradability, emulsifying agents, and low toxicity.…”

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.

“…In the same way, Deepika et al [50] used different statistical designs for optimization of rhamnolipid production by P. aeruginosa KVD-HR42. This Bs was of interest since like other rhamnolipids it showed high stability under extreme conditions of temperature, pH, and NaCl, as well as an attractive CMC.…”

Biosurfactants (Bs) have been studied for decades and applied in different industrial sectors because of their competitive biochemical characteristics, and the fact that they are environmentally friendly. Current scientific investigations mainly involve the search for novel Bs producing organisms with attractive characteristics. Bs are expected to replace synthetic surfactants in the near future, but low production yields and inefficient downstream processes have prevented their widespread use. Although there are numerous reports on Bs optimization, to date there has been no critical compilation or revision of the statistical designs and strategies employed for improved production. The purpose of this mini review is to briefly discuss the factors that affect Bs production and the importance of statistical design as an essential tool for increasing production.
