2019年4月23日 · Chalcomycin A and chalcomycin B (Figure 4c) were isolated from the marine strain Streptomyces sp. B7064 derived from mangrove sediment near Pohoiki, Hawaii (Pacific Ocean). Both compounds exhibited excellent activities against bacteria Staphylococcus aureus (MIC 0.39 µg/mL) and Bacillus subtilis (MIC 6.25 µg/mL), and low activities against ...

2002年10月25日 · A new macrolide antibiotic was isolated from the culture broth of a marine Streptomycete isolate B7064 together with chalcomycin as the active principles and the structure of the new antibiotic was determined by EI and ESI MS, 1H, 13C and 2D NMR spectroscopy and by comparison of the NMR data with those of chalComycin.

The B7064 is a link route in two parts on the west and north western sides of Kilmarnock in Ayrshire. The first, relatively recent, section is a short link running for just under a mile from the A759 north, across the A71 to meet the A7081.
