Streptomycin Resistance in a Streptomycin-Producing Microorganism [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1979
Cell-free extracts of Streptomyces bikiniensis contain an adenosine 5′-triphosphate-dependent kinase which inactivates streptomycin (Sm) and dihydrostreptomycin by phosphorylation. The products have been identified as streptomycin 6-phosphate and dihydrostreptomycin 6-phosphate.

Chemical Assay of Streptomycin B (Mannosido – Streptomycin) [PDF]

open access: yesNature, 1948
MORRIS1 has recently described the use of new reagent (0·2 per cent anthrone, a reduction product of anthroquinone, in 95 per cent sulphuric acid) for quantitative determination of carbohydrates. We have found that it can be used not only for distinguishing streptomycin B (a mannoside) from streptomycin A, but also for estimating the amount of the ...
