Enhancement of autofluorescence of the brown-rot fungus Piptoporus betulinus by metal ions.

abstract：:Substitution with NO2, Cl, Br and I into position 6 of 2-benzthiazolthiol derivatives increased their antimicrobial efficiency while the SH group is preserved. This increase affected both G+ and G--bacteria, mycobacteria and some fungi. The degree of efficiency of the benzthiazol derivatives is also influenced by the ...
