Age-related changes in the mycophilic fungus Didymocladium ternatum (Bon: Age-related changes in the mycophilic fungus Didymocladium ternatum (Bon.) Sacc. during submerged cultivation. Likhachev, A. N.; Anokhina, N. I.; Vasin, V. B.; Mukhina, L. N.; Shuvalova, I. A. (Vses. Nauchno-Issled. Inst. Bakprep., Moscow, USSR). Vestn. Mosk. Univ., Ser. 16: Biol., (3), 80-3 (Russian) 1977. CODEN: VMUBDF. DOCUMENT TYPE: Journal CA Section: 16 (Fermentations) D. ternatum in submerged culture passed through 6 distinct growth stages, with respect to morphol. and reaction to std. dyes, when grown for 88 h in a rotary shaker with a good aeration rate. Max. growth took place during the 1st 2 stages (48 h total) and ternatin [571-71-1] formation took place in later stages, reaching a max. rate during stage 5 (64-72 h).

Lethal and mutagenic effect of nitrosomethylbiuret on a culture of the mycofilic fungus Didymocladium ternatum: Lethal and mutagenic effect of nitrosomethylbiuret on a culture of the mycofilic fungus Didymocladium ternatum. Shuvalova, I. A.; Bartoshevich, Yu. E.; Domracheva, A. G.; Aleshina, O. A.; Vasin, V. B. (All-Union Res.Several reagents with their cas registry numbers 571-71-1 and 13860-69-0 are used here. Inst. Antibiot., Moscow, USSR). Antibiotiki (Moscow), 21(10), 892-6 (Russian) 1976. CODEN: ANTBAL. DOCUMENT TYPE: Journal CA Section: 3 (Biochemical Interactions) N-nitroso-N-methylbiuret [13860-69-0] exerted lethal and mutagenic activity on D. ternatum cultures, with the exact effects depending on exptl. conditions. The optimal conditions for producing variants with increased ternatin (I) [571-71-1]-synthesizing ability were a 28.degree. temp., a mutagen concn. of 0.15%, and a 1-hr exposure time. Variants with 4-8 times the antibiotic-synthesizing activity of the original fungus strain were obtained by selection of active variants. Their activity was retained through 3 passages and storage for 6 months. .
