“…The characteristics of biosurfactants isolated from B. haynesii strain SAII using NMR spectroscopy showed the specific spectrum similar to Bacillus species reported earlier (Sana et al, 2017) and also similar to surfactin as reported by (Yeh et al, 2005). The 1 H‐NMR spectra correspond to multiple peaks to aromatic amide (NH) protons at delta ( δ ) 7.380–8.175 ppm and also from δ 0.830 to 2.507 ppm (Figure 8) confirming the presence of long aliphatic (CH 2 ) chain of hydrophobic moiety (Cruz et al, 2018). Due to the presence of different lengths in peptide sequences, fatty acids and its similar isoforms, the surfactin protein present in biosurfactants also differ (Kanakdande & Khobragade, 2020).…”

The Sambhar Salt Lake in Rajasthan, India, offers a unique opportunity to explore halophilic surfactin-producing microorganisms with industrial application. The phylogenetic study, comparative genomics combined with chemotaxonomic research provided insight into the interspecies relativeness of Bacillus sp. Considering the nonribosomal protein sequences (NRPS), Bacillus haynesii strain SAII strain and Bacillus swezeyi strain SEIII showed a high degree of conservation. In silico studies of the isolated Bacillus sp. confirmed the presence of NRPS indicating the presence of surfactin-type lipopeptide biosurfactants. Structural investigation using Fourier transform infrared spectroscopy, liquid quadrupole triple quadrupole mass spectrometry, 1 H Nuclear mass resonance of the crude biosurfactant revealed further similarities among these two Bacillus species. Methyl esters of the crude biosurfactant indicated high likeliness among them and indicated the presence of pentadecanoic acid and tetradecanoic acid as the crucial fatty acids. Enhanced recovery of oil from contaminated sand using 100% crude biosurfactant ranged from 20% AE 0.05 to 69.20% AE 1.22. This opens the door to a bright future for understanding the molecular diversity of closely related halophilic Bacillus sp. and the potential use of the extracted biosurfactants for bioremediation of contaminants.

“…Biosurfactant production by B. subtilis using pure and waste glycerol derived from biodiesel production as a carbon source has been studied by several authors. The amount of surfactin produced ranged from 0.20 to 1.38 g/L [21,[36][37][38][39]. However, this is the first report dealing with surfactin production using soap-derived waste glycerol.…”

Sustainable Surfactin Production by Bacillus subtilis Using Crude Glycerol from Different Wastes

Most biosurfactants are obtained using costly culture media and purification processes, which limits their wider industrial use. Sustainability of their production processes can be achieved, in part, by using cheap substrates found among agricultural and food wastes or byproducts. In the present study, crude glycerol, a raw material obtained from several industrial processes, was evaluated as a potential low-cost carbon source to reduce the costs of surfactin production by Bacillus subtilis #309. The culture medium containing soap-derived waste glycerol led to the best surfactin production, reaching about 2.8 g/L. To the best of our knowledge, this is the first report describing surfactin production by B. subtilis using stearin and soap wastes as carbon sources. A complete chemical characterization of surfactin analogs produced from the different waste glycerol samples was performed by liquid chromatography–mass spectrometry (LC-MS) and Fourier transform infrared spectroscopy (FTIR). Furthermore, the surfactin produced in the study exhibited good stability in a wide range of pH, salinity and temperatures, suggesting its potential for several applications in biotechnology.

“…A recent work on fortifying agricultural feedstock with crude glycerol and Mn yielded an enhanced growth and 793 mg l −1 of crude lipopeptide (Cruz et al . ). Mn was speculated to increase the usage of ammonium nitrate by the microbial culture thereby increasing the availability of free amino acids for surfactin synthesis.…”

Biosurfactant production: emerging trends and promising strategies

Biosurfactants are economically most sought after biotechnological compounds of the 21st century. However, inefficient bioprocessing has mitigated the economical commercial production of these compounds. Although much work is being done on the use of low-cost substrates for their production, a paucity of literature exists on the upcoming bioprocess optimization strategies and their successes and potential for economical biosurfactant production. This review discusses some of the latest developments and most promising strategies to enhance and economize the biosurfactant production process. Recent market analysis, developments in the field of optimally formulated cost credit substrates for enhanced product formation and subsequent process economization are few of the critical aspects highlighted here. Use of nanoparticles and coproduction of biosurfactant along with other commercially important compounds like enzymes, are other upcoming bioprocess intensification strategies. The recent developments discussed here would not only give an overview of pertinent parameters for economic biosurfactant production but would also bring to fore multiple strategies that would open up new avenues of research on biosurfactant production. This would go a long way in making biosurfactants a commercially successful compound of the current century.
