8/25/2023 0 Comments Carbon pigment![]() The production of microbial pigments has two basic approaches:Ī) Finding new strains of pigment producing microbes from diverse environments and enhance their productivity.ī) Achieving enhanced yields from the already recognized species either by strain improvement and process development.Ĭurrently, the use of natural colorants has been encouraged and protected by laws and this inclination will continue in the coming years too. Nevertheless, the task of discovering potent novel microbial pigments for the optimal applications in food and pharma products, in spite of several research studies is still a challenging one requiring appropriate approaches ( Sen et al., 2019) and this review suggests the ways and means to overcome such challenges in this field. Changing nature of such kind of the industrial behavior have enthused both academia and industries to discover renewable and biodegradable natural products from microbial resources. Industries of late, have resorted to use many important microbial metabolites like antibacterials, antifungals, vitamins, enzymes, pigments, etc., for varied applications as being alternative ones to synthetic products. Further, the major challenge of lower stability of bacterial pigments and the solution to address it is also appraised. This review highlights the significance of bacterial colorants and summarizes its application in food and pharma industries. Tactics in strain improvement, fermentation conditions, metabolic engineering, and easy extraction techniques are needed to produce high end products. And, there is vast scope for easy and cheap production of natural colorants in all seasons from bacterial sources, compared to plant sources. Apart from serving as food colorants, bacterial pigments have several pharmacological activities like anti-microbial, anti-cancer, anti-oxidant, anti-inflammatory and anti-allergic properties with large economic potential. Literature establishes that the natural colorants produced from microbes were applied in food and pharma products successfully. The potential of bacterial pigments for mass production of diversified coloring properties was first prospective and is now getting the notable importance and attention of both the researchers and industries. ![]() So, it was indispensable to discover novel natural colorants such as microbial colorants which were safer and better than synthetic colorants. The continued universal application of synthetic colorants for decades have caused environmental pollutions and human health vulnerabilities.
