Background:

Kanosamine is the antibiotic produced by Bacillus cereus UW85. Kanosamine showed highly inhibitory effects to the growth of plant-pathogenic oomycetes and moderately inhibitory effects to certain fungi and inhibited few bacterial species tested. Kanosamine accumulation in B. cereus UW85 culture supernatants was enhanced by the addition of ferric iron and suppressed by addition of phosphate to rich medium. Kanosamine accumulation was also enhanced more than 300% by the addition of alfalfa seedling exudate to minimal medium [1].


Kanosamine was also produced by a Streptomyces SP [2]. Kanosamine inhibited cell wall synthesis in plant-pathogenic oomycetes with MIC value of 25 μg/ml for P. medicaginis M2913 and certain fungi as well as some bacterial species with MIC value of 400 μg/ml for S. aureus [1,2]. It has been explored as an alternative and/or supplement to synthetic pesticides and genetic resistance of crop plants for the management of plant disease [1,2].


The antibiotic kanosamine inhibited the growth of many human pathogenic fungi. Kanosamine was transported into cells by the glucose transport system and subsequently phosphorylated to generate kanosamine-6-phosphate. The product was an inhibitor of the enzyme glucosamine-6-phosphate synthase. The Inhibitory effect was competitive to one of the substrates, D-fructose-6-phosphate, with Ki value of 5.9 mM. The action of kanosamine on C. albicans cells lead to profound morphological changes, inhibition of septum formation and cell agglutination [3].
