    Notes: Summary Different strains of rhizobia (isolated fromLotus corniculatus andVigna unguiculata) andRhizobium meliloti adapt to sevin (50 μg/ml). The number of transfers (20–31) and days of incubation (80–130) during which different strains of rhizobia develop resistance varied. The results of reversion of resistance to sevin, experiments showed that the resistance developed was stable. Rate of growth was faster in resistant strains but their final cell numbers were less than those of sensitive strains. Dehydrogenase activity increased with the development of resistance to sevin, except in strain D-467. With the development of resistance to sevin, total lipids and phospholipids decreased, glycolipids increased and neutral lipids varied. Presence of glycerol, sodium oleate and sodium acetate (known to stimulate lipid production) and flavin mononucleotide and wheat germ lipases (known to decrease lipid production) in the culture medium did not change the growth pattern and lipids of the sevin resistant and sensitive strains of rhizobia.

    Effect of dithiocarbamates on cellulase activity in culture filtrates of Trichoderma reesei (1982)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 24 (1982), S. 1233-1240

    Notes: Different concentrations of tetramethylthiuram disulfide (TMTD), sodium dimethyldithiocarbamate (NaDDC), and zinc dimethyldithiocarbamate (ZnDDC) affected the amount of cellulase(s) activity in the culture of Trichoderma reesei. After eight days incubation at 28°C the greatest increase in Avicelase, CMCase, and β-glucosidase over the control were observed at 0.1 ppm (TMTD) and 0.4 ppm (NaDDC and ZnDCC). There was decrease in the growth in the ZnDDC, but β-glucosidase activity was reduced considerably. Total protein in the culture filtrate increased with the increase in cellulase(s) activity. No change in pH was observed at eight days incubation but pH increased (not exceeding 5.9) at 12 days incubation.
