It was positive for ornithine decarboxylase, gelatinase, reduction of nitrates to nitrites, tolerance to 6% NaCl, and assimilation of caprate and malate, but negative for citrate utilization, arginine dihydrolase, lysine decarboxylase, urease, indole production, assimilation of mannose, glucose, arabinose, mannitol, maltose, adipate, and acidification of glucose.
The most dominant routes of N removal from the introduced solution were N2 production and assimilation into macrophyte biomass, which were similar in magnitude for the vegetated plots, whereas N2 production dominated in the unvegetated plots.
Alcohol dehydrogenase (ADH), which catalyzes the interconversion between acetaldehyde and ethanol, plays a central role in ethanol production and assimilation.
Fig. 1 Biomass production and nutrient assimilation of T. lutea in three modes of culture.
Solvent production and acid assimilation were compared between the parental and engineered strains expressing only adhE2 CC101-SV44) and expressing adhE2, ald and ctfAB CC101-SV66).
Therefore, it is necessary to introduce both 2,3-BD production and xylose assimilation pathways into S. cerevisiae for producing 2,3-BD from xylose.
To improve H2 production, the nitrate assimilation pathway was disrupted by genetic engineering to redirect the electron flow towards the Hox-hydrogenase.
A wide and substantial definition of innovation is comprised by Crossan and Apaydin (2010) as the "production or adoption, assimilation, and exploitation of value added novelty in economic social spheres; renewal and enlargement of products, services, and markets; development of new methods of production, and establishment of new management systems.
Positive reactions were obtained for acetoin production and citrate assimilation.
Chlorophyll a increased with nitrogen-replete conditions as expected and, when nitrate was resupplemented after stationary phase, an increase in chlorophyll a (Fig. 2c) was observed, and these results suggest a switch from lipid accumulation to biomass production during nitrate assimilation.
Based on our experimental and literature data, production and re-assimilation of acetate might be over 1 mmol/g DCW at μ = 0.2 h-1 (Text S2 in Additional file 1) which further supports the hypothesis of the necessity for constant acetic acid synthesis.
