The on-line monitoring and control of methanol, the key inducer carbon source in fed-batch cultures, has enhanced the yield product/biomass 7.8-fold and the productivity 12.8-fold compared to the best batch cultivation with the Pichia system and, 10-fold compared to the fed-batch cultivation process using the native C. rugosa strain.
The results demonstrate how the BIM framework provides a decision support basis for evaluating the key carbon emission sources throughout a building's life cycle and exploring more environmentally sustainable measures to improve the built environment.
> -wrap-foot> Initial concentration of DM in wastewater = 0.05 ± 0,01 g l−1 When fatty substances are being used as a carbon source, the key factors influencing denitrification are the activities of enzymes participating in nitrate reduction (nitrate reductase) and fat hydrolyzing enzymes (lipases).
In addition, glutamine and glucose are key nitrogen and carbon sources for synthesis of all non-essential amino acids except tyrosine (Wise and Thompson, 2010).
The composition of PHAs depends on the PHA synthases (polymerases) (PhaC), the key enzymes for PHA biosynthesis, the carbon source and the metabolic routes involved (Rehm 2003; Rehm and Steinbüchel 1999).
Growth limitation, caused by e.g. limiting the availability of nitrogen, in the presence of a carbon source, is a key factor for obtaining high PHB titers in natural producers (Wang and Lee 1997).
Evolutionary engineering has been used to improve key industrial strain traits, such as carbon source utilization, tolerance to adverse environmental conditions, and resistance to chemical inhibitors, for many decades due to its technical simplicity and effectiveness.
The second key factor is the cost for the carbon source [ 279].
One would have thought that climate change might lead all parties to defend the rainforests, key carbon sinks that slow climate change, important sources of biodiversity and places of immense beauty.
This indicates, that Cre1, the key repressor of utilization of alternative carbon sources, does not mediate carbon source dependent metabolic state alterations in the central carbon metabolism of T. reesei.
