Although this work is focused on lab-scale fermentations, the purification method has already been validated in a high-density fermentation experiment with a 500 L fermenter, showing full recovery of the recombinant copolymer with high purity.
The fermentation experiment was repeated three times.
Based on these results, we designed a two-stage temperature control fermentation experiment.
The fermentation experiment was conducted at anaerobic condition and at the atmospheric pressure.
The esterase production was investigated in solid-state fermentation experiment using various fish processing waste meal.
The digestate for the semi-continuous fermentation experiment originated from an agricultural cooperative close to Grimma, Germany.
In case of fungal cell culture, fermentation experiment was allowed to process for four days after the final feed.
A biological fermentation experiment tank was used to provide the same experiment environment, which is shown in Fig. 4.
A continous-stirred tank reactor with a working volume of 31 L was used for the semi-continuous fermentation experiment.
The hydrogen autotrophic fermentation experiment was carried out in a 1 L serum bottle containing 400 ml of growth medium.
Upper panel shows a more detailed profile of H2S formation in the early stage of a separate fermentation experiment.
