Test Cultures

It was shown that Avercom and plant growths regulators act as weak mutagens on auxotrophic test-cultures Salmonella typhimurium TA 100 and TA 98. Their antimutagenic influence on test-cultures of Salmonella typhimurium TA 100 and TA 98 was studied. The addition of S. avermitilis UCM Ac-2177 biomass, cultural liquid and Avercom of different concentrations separately to soil increased the quantity of pedotrophic, amylolytic, phosphorus immobilizing and amonificating microbes.

Cuminic acid (9) was converted by reductive methylation into 1,2,3,6-tetrahydro-4-isopropyl-1- methylbenzoic acid (12). Acid-catalysed cyclization of the diazomethyl ketone (8) derived from (12), followed by hydrogenation, gave the bicyclo[3,2,l]octanone derivative (7), which was then converted through the allylic bromide mixture of (18) and (19) into the p-toluenesulphonyldithiocarbazone (21) and the allylic ammonium bromide (25). The [2,3]-sigmatropic rearrangement of the dithio- carbene derived from (21) and the ylid derived from (25) afforded the dithioester (22) and pyrrolidine (26), respectively, from which the alcohol (24), aldehydes (27) and (28), and acids (5) and (6) were prepared. Bioassay of (5), (6), (27) and (28) indicated gibberellin-like properties for all these compounds with potency comparable with that of helminthosporic acid (2).
