Algal and Microbial Production of Vitamin Emand for the vitamin has increased year after year. The supply of tocopherols has been limited to the chemically synthesized racemate of ar-tocopherol or a mixture of α-, ß(γ)- and ó-tocopherols extracted from vegetable oils.Robust 发表于 2025-3-27 03:21:28
Microbial Production of Vitamin B2 (Riboflavin)oflavin is used pure for human nutrition and therapy and in the crude concentrated form for animal feed supplements. Although it is produced by both synthetic and fermentation processes, it is believed that the microbial synthesis should be able to compete quite successfully with the synthetic chemical processes.meditation 发表于 2025-3-27 06:45:14
Microbial Production of ,-Ribosech important biopolymers in the hereditary material of organisms whereas other ubiquitous pentoses, .-arabinose and .-xylose, are usually present in the plant cell walls. Why the pentose components of nucleic acids are .-ribose and 2-deoxy-.-ribose is an unresolved problem; .-ribose and its derivatives have been also found widely in nature.舔食 发表于 2025-3-27 11:55:58
Microbial Production of Vitamin B12ly of the cobalt corrinoids. In this review, however, as in most publications, the word vitamin B. is given a very broad meaning so as to include all the cobalt corrinoids of the cobalamin group. Other cobalt corrinoids which can be considered analogous or precursors of cobalamins are also included.LUT 发表于 2025-3-27 15:06:47

β-Carotene (Provitamin A) Production with Algaeound in natural hypersaline waters where it colours the brines red (Teodoresco, 1905). This algal species was first recognised as containing high intracellular concentrations of β-carotene by Mil’ko (1963) and Aasen . (1969). Initial research on the potential of using this alga as a commercial sourchandle 发表于 2025-3-28 08:31:27
Production of Carotenoids with Fungiirect contributions from fungi, algae, and bacteria. Carotenoid production is rarely the main objective of a culture, but colourful products rich in carotenoids are obtained from various plants and algae. The oldest example is saffron (.), still planted in La Mancha, Spain, and elsewhere for the sti引导 发表于 2025-3-28 11:15:13
Microbial Production of Carotenoids other than β-Carotene. In 1831 Wackenroder prepared ‘carotene’ in crystalline form (Isler, 1971), whereas xanthophylls were first isolated from autumn leaves by Berzelius in 1837 (Isler, 1971). Following the main-classical chromatographic experiments of Tswett at the beginning of this century (Isler, 1971), it was soon
