The enzyme cellulase, a multienzyme complex made up of several proteins, catalyzes the conversion of cellulose to glucose in an enzymatic hydrolysis-based biomass-to-ethanol process. Production of cellulase enzyme proteins in large quantities using the fungus Trichoderma reesei requires understanding the dynamics of growth and enzyme production. The method of neural network parameter function m...

Tannase (tannin acyl hydrolase, E.C.3.1.1.20) is an important hydrolysable enzyme with innumerable applications and industrial potential. In the present study, a kinetic model has been developed for the batch fermentation used for the production of tannase by A.flavus MTCC 3783. Maximum tannase activity of 143.30 U/ml was obtained at 96 hours under optimum operating conditions at 35oC, an initi...

We demonstrate a generalized kinetic modeling and experimental approach to describe the formation and growth of single-walled metal oxide nanotubes. These materials can now be synthesized using solution-based methods at temperatures as low as 95 1C. Ultimately, it is desired to produce nanotubes on a larger scale (e.g., kilogram or ton) for technological applications. However, a quantitative mu...

The paper investigates the static and dynamic behavior of a continuous flow bioreactor for the aerobic biodegradation of municipal and industrial waste. The unstructured kinetic model for the bioreactor accounts for oxygen limitation in the bioreactor model while the growth rate is described by the biomass-dependent Contois model. This kinetic model is known to explain the aerobic biodegradatio...

The kinetic Monte Carlo (MC) model of nanowhisker (NW) growth is suggested. Two variants of growth are possible in the model—molecular beam epitaxy (MBE) and chemical vapor deposition (CVD). The effect of deposition conditions and growth regimes on the whisker morphology was examined within the framework of the vapor–liquid–solid (VLS) mechanism. A range of model growth conditions corresponding...

We present the results of simulations of kinetic growth trails (KGT) (bond-avoiding walks) in four dimensions. We use a mapping from a kinetic growth model to a static model of selfinteracting trails (ISAT) at a particular temperature to argue that this temperature is precisely the collapse temperature of four-dimensional interacting trails. To do this we show that the kinetic growth trails beh...
