This volume provides practical experimental laboratory protocols for a wide range of steroid bioconversions. The chapters in this book cover topics such as bioconversions and chemical synthesis pathways; strain characterization; bioconversion from sterols to androstenedione and androstadienedione; steroid hydroxylations; biocatalysis; and downstream processes to purify steroid intermediates. 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 tips on troubleshooting and avoiding known pitfalls. Comprehensive and thorough, Microbial Steroids: Methods and Protocols is a valuable resource for laboratory and industrial professionals. It is also useful for graduate students studying biotechnology, microbiology, genetics, and molecular biology.

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.

Carotenoids are a family of yellow to orange-red terpenoid pigments synthesized by photosynthetic organisms and many bacteria and fungi. They have beneficial health effects protecting against oxidative damage and may be responsible for the colours associated with plants and animals. In Microbial Carotenoids from Bacteria and Microalgae: Methods and Protocols, expert researchers in the field detail many of the most up-to-date methods which are now commonly used to study carotenoids. These include methods for the study of canthaxanthin production, construction of carotenoid reporter systems, directed evolution of carotenoid synthases, and improvement of b-carotene hydroxylase catalytic activity are described. Additionally, the book includes methods of DNA fingerprinting for the identification of carotenogenic Dunaliella species, ketocarotenoid biosynthesis in microalgae expressing the beta-C-4-carotene oxygenase gene, characterization of carotenogenesis genes in Anabaena sp., obtaining lutein from microalgal biomass, NMR-based isotopologue profiling of microbial carotenoids, and analysis of diapocarotenoids. 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.
