Yeast Carotenoids: Cost-Effective Fermentation Strategies for Health Care Applications
Debarati Paul, Panda Kusuma Kumari, Nahid Siddiqui
Abstract
Carotenoid production from oleaginous red yeast has been considered as a safe alternative to chemically synthesized carotenoids commonly used in the food industry, since plant-based carotenoids are expensive and an irregular source for obtaining pigments. This is a summative review on the factors affecting carotenoid production, cost-effective production strategies using various inexpensive feedstock, metabolic engineering, and strain improvisation. The review specially highlights the various potential applications of carotenoids as anti-microbial, anti-viral, antioxidant, anti-cancerous, anti-malarial agents, etc. The importance of such natural and easily available resources for prevention, evasion, or cure of emerging diseases and their plausible nutraceutical effect demands exhaustive research in this area.
