title: Kluyveromyces marxianus: a potential source of diacetyl reductase.
abstract: Kluyveromyces marxianus had a higher specific activity of diacetyl reductase (EC 1.1.1.5) than all other organisms previously reported. The enzyme was NADH-dependent and irreversibly catalysed the conversion of diacetyl to acetoin with an optimum pH of 7.0. It was stable at 40°C but lost 50% of its activity at 50°C in 30 min. The K m and V max values for diacetyl were 1.8 mM and 0.053 mM/min, respectively.
