Table 1 Respiration activity of analyzed O. polymorpha strains

From: Transcriptional activator Cat8 is involved in regulation of xylose alcoholic fermentation in the thermotolerant yeast Ogataea (Hansenula) polymorpha

Strain Respiration (nanomoles of O2 consumed per minute per mg of cells at 30 °C)
Glucose as substrate Xylose as substrate
WT 11.81 ± 0.52 11.35 ± 0.56
cat8Δ 8.49 ± 0.07 7.08 ± 0.14
BEP 11.87 ± 0.59 17.17 ± 0.86
BEP cat8Δ 13.98 ± 0.70 10.53 ± 0.02
  1. Determinations were performed in distilled air-saturated water with the concentration of cells 0.5 g/L of dry weight and started by addition of 1% carbon substrate (glucose or xylose). The respiratory rate was expressed as nanomoles of O2 consumed per minute per mg of cells (dry weight)
