The methane monooxygenase (MMO) enzyme, used by methylotrophs
to oxidize methane, has been shown to possess quite broad substrate
specificity, being able to oxidize many organic compounds including
n-alkanes, n-alkenes, ethers, and aromatic, alicyclic, and
heterocyclic compounds. In this research, it was sought to
determine whether a gas-permeable-membrane-supported (GPMS) biofilm...
Cyanobacteria inhabit nearly every ecosystem on earth, play a vital role in nutrient cycling, and are
useful as model organisms for fundamental research in photosynthesis and carbon and nitrogen fixation.
In addition, they are important for several established biotechnologies for producing food additives,
nutritional and pharmaceutical compounds, and pigments, as...
The growth characteristics of Thermosynechococcus elongatus on elevated CO₂ were studied in a photobioreactor. Cultures were able to grow on up to 20% CO₂. The maximum productivity and CO₂ fixation rates were 0.09 ± A 0.01 and 0.17 ± A 0.01 mg ml⁻¹ day⁻¹, respectively, for cultures grown on 20%...
Cometabolic biodegradation processes, important for bioremediation of hazardous waste sites, are not well understood and have not been modeled thoroughly. Toxic effects and bacterial responses to toxicity may change intracellular enzyme levels, rendering traditional enzyme kinetics models inappropriate. This document presents a novel cometabolic enzyme kinetics model that incorporates enzyme...
