In the present study, eleven endophytic bacterial strains, Herbaspirillum sp. (GP-SGM1, GP-SGM2, GP-SGM3, and GP-SGM11), Pseudomonas sp. (GP-SGM4, GP-SGM5), Novosphingobium sp.

Due to triacylglycerol (TAG) profiles that are abundant in medium-chain fatty acids, diatoms have emerged to be better feed stocks for biofuel production, in comparison to the commonly studied green microalgal species (chlorophytes). Importantly, diatoms are also known for their high levels of the essential ω3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and are considered to be a promising alternative source of these components.

- Microalgae have potential for producing biofuels and valuable compounds, but challenges like low product yield hinder commercial production.
- Researchers enhanced triacylglycerol (TAG) accumulation in a diatom strain by expressing a yeast acyltransferase and a plant oleosin protein.
- The co-expression led to a 3.6-fold increase in TAG content, and more lipid droplets were observed, especially under nitrogen stress, while fatty acid composition stayed unchanged.
Solar energy provides the energy input for the biosynthesis of primary and secondary metabolites in plants and other photosynthetic organisms. Some secondary metabolites are high value compounds, and typically their biosynthesis requires the involvement of cytochromes P450s. In this proof of concept work, we demonstrate that the cyanobacterium Synechocystis sp.
