the invention belongs to the technical field of microorganisms, and particularly relates to Streptomyces sp SCSIO 15077 and a neomycin E extracted and separated from the strain.
Background art:
natural products have been an important source for innovative drug development. According to the statistics of Newman D J and Cragg G M, 49 percent of the medicines approved by the United states Food and Drug Administration (FDA) during the period of three decades from 1981-2014 are derived from natural products and derivatives thereof. Wherein, 80% of the anti-tumor drugs and 50% of other drugs are derived from natural products and derivatives thereof. The ocean contains abundant biological resources, the biomass of which accounts for about 87 percent of the total amount of the terrestrial organisms, and the variety of the marine organisms is as much as 20 to more than ten thousand. The marine environment has special environments such as high salt, high pressure, low temperature, low oxygen, low nutrition, low illumination and the like, and actinomycetes living in the marine environment can synthesize secondary metabolites with unique activity and novel structure, so that the actinomycetes can be used as important drug source microorganisms for a long time to be applied to research and development of antibiotics, anti-tumor drugs and other drugs. After the new century, with the deep sea exploration of human beings, the research of the secondary metabolite with the new structure in the marine actinomycetes as the drug lead compound shows a rapid growth trend, and the secondary metabolite is a rapidly rising emerging field.
Tunicamycin belongs to nucleoside antibiotics and consists of four units, namely uracil (uracil), chlamydomonas sugar (tunicamine), N-acetylglucosamine (GlcNAc) and an aliphatic chain. Tunicamycin was originally isolated from streptomyces s, chartreussis, by japanese scholars, but as a mixture. According to statistics, the strains Clavibacter species, S.chartreusis and Corynebacterium rathayi can produce the antibiotics. At present, 37 monomeric compounds of tunicamycin are obtained by co-separation, and named after tunicamycins, streptovirins, mycosporins, MM 19290 and coresyntoxins. Tunicamycin has good inhibitory effect on most gram-positive bacteria and fungi. Wherein the average value of the Minimum Inhibitory Concentration (MIC) of Bacillus thuringiensis (Bacillus thuringiensis) is 1.27 mu g/mL, which is superior to positive controls such as vancomycin and kanamycin. MIC for Candida albicans (Candida albicans) was 2-32. mu.g/mL. Due to the unique pharmacological actions, tunicamycin is expected to be developed into a novel antibacterial and bactericidal medicine.
