    摘要: (5-Nitro-2-furyl)vinylene-2-trimethylammonium bromide having the formula ##STR1## is suitable as a starting raw material for a plurality of syntheses of 5-nitro-2-furyl ethylene compounds possessing an antibacterial effect. The method of preparing the bromide involves reacting 1-(5-nitro-2-furyl)-2-bromoethylene with trimethylamine in an organic solvent medium at a temperature of from -10 .degree. to +50.degree. C.

    摘要: It has been found that cycloheximide production by a culture of Streptomyces griseus is maintained and total yields of the antibiotic are increased when a glucose feed is begun at about 48 hrs. and continued until the culture becomes senescent at about 8 to 10 days.
