ABOELNAGA, Mohamed et al. Screening local marine habitats suggests a novel Bacillus subtilis MZ1 strain as a potential fatty acid producer. Biotecnia [online]. 2024, vol.26, e2058.  Epub 18-Out-2024. ISSN 1665-1456.  https://doi.org/10.18633/biotecnia.v26i1.2058.

Within this academic research article, a bacterium isolated from a marine soil environment near the Mediterranean Sea is observed to possess the potential for producing various fatty acids, particularly n-caproic and oleic acids, as evidenced by FAME profiling. Furthermore, the introduction of glucose into the growth medium enhances the production of caprylic acid rather than caproic acid. The 16S rDNA sequencing suggested that the MZ1 strain belongs to Bacillus subtilis and is closely related to many halophilic species. FAME profiling reveals that the isolated MZ1 is competent in the total production of fatty acids compared to other marine bacterial candidates. Furthermore, the results indicate that MZ1 is efficient in the production of many other fatty acids. This exploration suggests that the marine bacterium Bacillus subtilis MZ1 can be used for fatty acids synthesis, which could be valuable for biodiesel production and other applications.
