In this volume, expert researchers in the field detail the most up-to-date methods commonly used to study and produce carotenoids. These include methods on the manipulation and metabolic engineering of carotenoid producing microalgae and bacteria, including Corynebacterium glutamicum, Rhodopseudomonas palustris and radio-tolerant bacteria; in addition to fungi, as the beta-carotene producing Blakeslea trispora and Mucor circinelloides or the lycopene producing Blakeslea trispora; and the heterobasidiomycetous yeast producing xanthophylls Xanthophyllomyces dendrorhous (Phaffia rhodozyma) and the engineered yeast Pichia pastoris. Additionally, three overview chapters on the advancement of Biotechnology and carotenoid production are included. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Microbial Carotenoids: Methods and Protocols provides practical experimental laboratory procedures for a wide range of carotenoids producing microorganisms, aiming to ensure successful results in the further study of this vital field.
