1.D-Ribose fermentation by Bacillus subtilis C1-B941, a transketolase mutant, was carried out on a pilot plantscale.
使用转酮醇酶变异株—枯草芽孢菌C1-B941进行了D-核糖发酵中间试验。
2.Cyanoguanidine and acetylated β-D-ribose were used as starting materials to give target compound via salt formation, cyclization, silylation, coupling reaction and deprotection.
3.Inosine is a molecule (known as a nucleoside) that is formed when hypoxanthine is attached to a ribose ring (also known as a ribofuranose) via a β-N9-glycosidic bond.
