A pure bacterial culture utilizing chromates and bichromates as oxygen donors during growth on organic substances in anaerobic conditions was isolated from active ooze of sewage and industrial wastes containing a weak solution of chromates. A medium for growth of the bacterium was selected, and its morphological and cultural properties were studied.(More)
Daily administration of tubuloclustin (1 mg/kg, 5 d, i.p.) to BDF1 mice with i.p. transplanted P388 leukemia extended statistically significantly by 45% their life spans compared with those of untreated controls (17 vs. 11.7 ± 3 d). The possibility in principle of preparing 2-methoxyestradiol analogs with a linker bonded through a steroid C6 ester was(More)
Distinct bacterial growth can be discerned in the surface water film on semisubmerged slides in the laboratory conditions. The thickness of growth depends on the content of organic substances in water. The growth is found also in natural brine if the content of salts is 127--230 g per litre. A great variety of aqueous bacteria is seen, by means of electron(More)
Traditional single species toxicity tests and multiple component laboratory-scaled microcosm assays were combined to assess the toxicological hazard of diesel oil, a model complex mixture, to a model aquatic environment. The immediate impact of diesel oil dosed on a freshwater community was studied in a model pond microcosm over 14 days: a 7-day dosage and(More)
Anthraquinones and their analogues, in particular heteroarene-fused anthracendiones, are prospective scaffolds for new compounds with improved antitumor characteristics. We herein report the use of a 'scaffold hopping' approach for the replacement of the core structure in the previously discovered hit compound naphtho[2,3-f]indole-5,10-dione 2 with an(More)
