Effects of salts on aerobic metabolism ofDebaryomyces hansenii

Abstract: Debaryomyces hansenii was grown in YPD medium without or with 1.0 M NaCl or KCl. Respiration was higher with salt, but decreased if it was present during incubation. However, carbonylcyanide-3-chlorophenylhydrazone (CCCP) markedly increased respiration when salt was present during incubation. Salt also stimulated proton pumping that was partially inhibited by CCCP; this uncoupling of proton pumping may contribute to the increased respiratory rate. The ADP increase produced by CCCP in cells grown in NaCl was si… Show more

“…Under our experimental conditions, the growth rate of these cells increases independently of the osmolite present in the media (Fig 2, typical traces are shown in Panels A, quantifications are depicted in Panel B). This result agrees with previous reports [12, 13]. …”

“…The levels of ADP were measured and reported before for the cells grown in the presence of NaCl, and incubated in the absence or presence of either KCl or NaCl, and no significant differences were found (Sánchez et al, 2008). A similar situation was observed when the cells grown in the absence of salt were incubated without or with KCl or NaCl (Fig.…”

“…This appears to be the result of changes in their enzymatic pattern deviating the metabolism of glucose toward the glycolytic pathway by (1) the decreased activity of the tricarboxylic acid cycle in favor of the glyoxylate cycle (Sánchez et al, 2008); (2) an increase of the phosphofructokinase activity, one of the limiting enzymes of glycolysis; and (3) a moderate relative increase of ADH and G3PDH reported here.
