An ethionine-resistance gene cloned from Saccharomyces cerevisiae DKD-5D-H was able to enhance S-adenosyl-l-methionine (AdoMet) accumulation when it was introduced into the yeast cells on multi-copy plasmid YEp13. In order to increase the AdoMet accumulation, the gene was integrated into the yeast chromosome by using a yeast transposon Ty element. When the(More)
We found that penicillin-induced glutamate production by Corynebacterium glutamicum is inhibited when a de novo protein synthesis inhibitor, chloramphenicol, is added simultaneously with penicillin. When chloramphenicol was added 4 h after penicillin addition, glutamate production was essentially unaffected. 3H-Leucine incorporation experiments revealed(More)
The growth kinetics of anchorage-independent animal cells [mouse myeloma MPC-11 (ATCC CCL 167) immobilized within porous polyvinyl formal resin biomass support particles (BSPs; 3 × 3 × 3 mm cubes; mean pore diameter, 60 µm) was analyzed by measuring intracellular and extracellular lactate dehydrogenase (LDH) activities in a perfusion culture. First, the(More)
