Biologically active compounds of semi-metals

“…In a screening of myxobacteria for antibacterial metabolites, the Sorangium cellulosum strain So ce678 was selected for its activity against Staphylococcus aureus (Schummer et al, 1994(Schummer et al, , 1996Irschik et al, 1995). The active compounds were two rather lipophilic tartrolons B (9) and C (10).…”

— Cadmium Bioremediation by a Resistant Streptomyces Strain

“…A great number of metabolites exist which are synthesized by bacteria containing Boron such as aplasmomycines (Nakamura et al 1977), tartrolones A and B (Irschik et al 1995), boromycines (Kohno et al 1996) and borophycines (Arai et al 2004). Cyanobacteria Nostoc spongiaeforme var.…”

“…nov. (Ahmed et al 2007a) are the only bacteria in which boron has been determined to be essential for growth. On the other hand, there are many well known metabolites containing boron synthesized by bacteria, like aplasmomycins (Nakamura et al 1977), tartorlon A and B (Irschik et al 1995), boromycin (Kohno et al 1996) and borophycin (Arai et al 2004).…”

Histological Evaluation of the Effects of Borax Obtained from Various Sources in Different Rat Organs

“…Although boron has a very low toxic effect on mammals, it is very toxic to arthropods and used for insecticides. On the other hand, boric acid another form of boron, is used as an antibiotic in some superficial infections in humans (Irschik et al, 1995).…”
