Termitomyces clypeatus is a fungus species, which has been used as food and medicinal mushroom. In the current study, submersed fermentation of in stirred-tank bioreactor was determined for its culture biomass nutrient contents. T. obtained highest after from 13 to 15 days cultivation, when dry mycelium system more than 6%. Agitation speeds 150 or 180 rpm were most suitable fungus. The determin...

This work was to investigate the hypoglycemic and antioxidant activities of the exopolysaccharides produced in a stirred-tank bioreactor by Inocutus hispidus. The exopolysaccharides showed significant antioxidant activities, up to 70.7±2.5% inhibition of hydroxyl radicals, 50% inhibition of 2,2-diphenyl-1-picrylhydrazyl radicals, and a Trolox equivalent antioxidant capacity of 3.3 mM. The exopo...

This paper applied a new Kalman Filter Recurrent Neural Network (KFRNN) topology and a recursive Levenberg-Marquardt (L-M) learning algorithm capable to estimate parameters and states of highly nonlinear unknown plant in noisy environment. The proposed KFRNN identifier, learned by the Backpropagation and L-M learning algorithm, was incorporated in a direct and indirect adaptive neural control s...

Abstrad This paper proposes a new Kalman Filter Recurrent Neural Network (I0 topology and a recursive Levenberg-Marquardt (L-M) second order learning algorithm capable to estimate parameters and states of highly nonlinear bioprocess in a noisy environment The proposed KFRNN identifier, learned by the Backpropagation and L-M learning algorithm, was incorporated in a direct adaptive neural cont...

The optimization of the operation of biological reactors is an interesting non-linear problem whose solution o!ers potential economic bene"t. We apply a peak seeking method to approach the maximum biomass production rate in a continuous stirred tank bioreactor. Two models, Monod and Haldane, are investigated and it is shown by simulation that the peak seeking scheme achieves optimization for bo...

In this work, a novel stirred tank for the production of H2 by the biological fermentation of organic wastes is presented. The bioreactor design must ensure effective mixing of the liquid phase, full contact between the substrate and the biofilm and energy efficient biogas recovery. A vortexingesting dual impeller stirred vessel equipped with a central draft tube containing the packing support ...

In the future, due to limited resources, a crisis of energy storing molecules (fuels), which are currently produced from crude mineral oil, is expected. One strategy to compensate a part of the oil defi ciency is the production of biodiesel from microalgal lipids. As model microorganism for lipid production microalgae Euglena gracilis was selected and photo-mixotrophic cultivation was performed...
