Carotenoid has gained a reputation amongst researchers for its robust antioxidant capabilities. This review reasons the inevitability of carotenoid for a larger role than just dietary supplements. In an era dominated by chemical or plant-derived carotenoid, bacterial carotenoid provides a compelling forte to be exploited as a promising alternative. Bacteria are amazingly resourceful beings; however, their low carotenoid content makes them undesirable for commercial applications. Here, we have reviewed their applications as a strong prophylactic agent in the health sector with a myriad of applications. Additionally, various measures for augmenting carotenoid yield through new-age technologies, like sequential nutrition starvation, the induction of carotenoid accumulation in microbial cells by employing several stress factors, and the construction of hyper-carotenoid producing strains through genetic engineering for creating proficient producers have been offered. Finally, SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis has been presented to perceive the significance of four major components involved in its commercialisation.

细菌作为类胡萝卜素生产的替代生物工厂:其应用,机遇和挑战的回顾

类胡萝卜素因其强大的抗氧化能力而在研究人员中享有盛誉。这项审查的原因是类胡萝卜素不可避免地要发挥作用,而不仅仅是膳食补充剂。在化学或植物类胡萝卜素占主导的时代,细菌类胡萝卜素提供了令人信服的优势,可被用作有前途的替代品。细菌是非常足智多谋的生物。然而,它们的低类胡萝卜素含量使它们不适合商业应用。在这里,我们回顾了它们作为保健领域的强力预防剂的应用,并有无数的应用。另外,通过新时代技术增加类胡萝卜素产量的各种措施,例如连续营养匮乏,利用多种压力因素诱导微生物细胞中类胡萝卜素积累,并且已经提出了通过基因工程构建高类胡萝卜素生产菌株以创建熟练生产者的方法。最后,提出了SWOT(优势,劣势,机会和威胁)分析,以了解其商业化涉及的四个主要组成部分的重要性。
