In recent years the discovery of some most important antibiotic compounds obtained by fermenting environmental microbes has been reported, providing proof that isolation and fermentation of producer strains is a significant approach to decifer novel structural types of antibiotics. Whereas many microbial ...
- Cyanobacteria, which are a type of bacteria, primarily engage in photosynthesis and nitrogen fixation but are not known for producing antibiotics. 5. Conclusion: - Based on the information, antibiotics are mostly obtained from fungi and actinomycetes. Therefore, the correct answer to the question...
But the high productivity achieved in the early 1990s continued when antibiotics were banned3 — and resistance to many of the 11 banned antibiotics more than halved in bac- teria obtained from animals and humans. The United States, where antibiotics are still widely used as growth promoters, ...
(1)细节理解题。根据第三段To look for alternatives,David Thomas at Cardiff University in the UK and his colleagues investigated chemicals obtained from the liquid of the blush wood tree,which grows in Australia.(为了寻找替代品,英国卡迪夫大学的大卫
Oligo- deoxyribonucleotides were obtained from Sigma-Genosys (Supplementary Table S5). DNA templates carrying a T7 promoter sequence for in vitro transcription were generated by PCR using genomic DNA (E. coli K12 strain). The primers used to generate templates for the transcription of mutS mRNA...

倒数第二段“Nowadays,doctors find antibiotics that once worked against the infections no longer work.The bacteria have learned ways to fight against the drugs.The heavy use of antibiotics in animals is responsible for the growth of antibiotic resistance worldwide.In the United States,at least two...
The bacteria were treated with different concentrations of BSS (μM) for 2 hours, then the inner membrane was collected and membrane-bound NADH-quinone oxidoreductase activity was measured. c–f, BSS dose-dependent inhibition on the activity of NADH dehydrogenase from different gene mutant ...
The obtained complex structure showed a clear compound binding site that gave additional electron density compared with the protein, clearly found inside the mtCcO (Supplementary Fig. 2a). The Fo(T113)–Fo(DMSO) differential map confirmed that this electron density did not originate from water or...
