Abstract

Omega-3 fatty acids or polyunsaturated fatty acids known as are indispensable to human health and are more commonly referred to as “healthy fats.” These include improving neuronal functioning and promoting cardiac health by decreasing triglycerides, as well as controlling blood pressure, reducing hypertension, improving mental health, and checking microbial proliferation in the body. Only meals rich in n-3 FA can provide us with these essential FA as the human body is unable to generate them. Plants are a rich source of ALA, while seafood is known for containing significant levels of DHA and EPA. These food sources have their own drawbacks, such as the potential for heavy metal contamination with mercury, disagreeable taste and odor, and difficulties in being accepted by vegans and vegetarians. Plants are not thought to be a trustworthy supply of these fatty acids due to their slow growth, inconsistent synthesis, and complicated enzyme system. Consequently, research has been done on microbial sources as prospective sources of the crucial omega-3 fatty acids. Commercially produced n-3FAs from cultivated microorganisms under controlled conditions have shown improved FA synthesis and quick development. Moreover, modifications can be done in microorganisms by genetic engineering much more easily than higher organisms. In this context, the significance of microalgae has also been investigated and confirmed. This paper talks about the significance of n-3 FA and the possibility for bacteria to produce them in greater and more widespread amounts.
