Starch dialdehyde thiosemicarbazones of various degree of substitu-Thiosemicarbazone von Starkedialdehyd und ihre biologische tion were prepared and their biological activity studied against some Aktivitat. Es wurden Thiosemicarbazone von Starkedialdehyd versaprophytes, fungi and Mycobacterium tuberculosis. schiedener Substitutionsgrade hergestellt und ihre biologische Aktivitat gegenuber einigen Saprophyten, Pilzen und Mycobacterium tuberculosis wurde untersucht.

Syntheses of alkanosulfonylated starches are presented with alkane moiety being 1‐propyl‐, 1‐butyl‐, 1‐octyl, 1‐decyl‐ and 1‐octadecyl. Some properties of these compounds are described and results of their biological screening against Escherichia coli, Bacillus subtilis, Aspergillus niger and Aspergillus flavus are given.
