چکیده

Answer 3, Fermentor is a closed vesselanaerobically maintained,restricted for microbial,prokaryotic cells,and operated in small scale. Bioreactor is used.bioreactor fermentor of almost industrial. Hysteresis, cascade and PID and transition conditions between different process steps applying logic functions.fermentor -provides required optimal conditions for bacteria or fungi to grow to produce requiredyield of substance bioreactorvessel which carries chemical.Nutrients may be continuously added to the fermenter, as in a fed-batch system, or may be. Typically bioreactors are cleaned between batches, or are designed to reduce fouling. Or therapeutic purposes, the design is significantly different from industrial bioreactors.

Bacterial community dynamics during start-up of a trickle-bed bioreactor degrading aromatic compounds.

This study was performed with a laboratory-scale fixed-bed bioreactor degrading a mixture of aromatic compounds (Solvesso100). The starter culture for the bioreactor was prepared in a fermentor with a wastewater sample of a care painting facility as the inoculum and Solvesso100 as the sole carbon source. The bacterial community dynamics in the fermentor and the bioreactor were examined by a con...

Polygalacturonase Production by Aspergillus sp. in Air-Lift and Agitated Fermentor

Polygalacturonase production under different shear stress environments by Aspergillus sp. was studied. It was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm. On the other hand, in a split cylinder air-lift fermentor, the rate of polygalacturonase production slightly increased with increasing in air ...

MOLECULAR CHARACTERIZATION AND OPTIMIZATION OF VI-CAPSULAR POLYSACCHARIDE OF SALMONELLA TYPHI TY6S PRODUCTION IN BIOREACTOR

The role of Vi-capsular polysaccharide (Vi-CPS) in human immunity against infection caused by Salmonella typhi is well known. The downstream process of purification generally causes depolymerization of Vi-CPS to a nonimmunogenic low molecular weight form. In the present study, a standard strain of Sal. typhi Ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 Liter fe...

Production of a high viscosity polysaccharide, methylan, in a novel bioreactor.

The effect of shear stress on the production of a high viscosity polysaccharide, methylan, from methanol by Methylobacterium organophilum was investigated by using a multidisk mixer. It was observed in the multidisk mixer with defined shear stresses that the specific production rate of methylan increased gradually with increasing shear stress up to 30 Pa, and the production rate was constant be...

Process analysis of the conversion of styrene to biomass and medium chain length polyhydroxyalkanoate in a two-phase bioreactor.

The improvement and modeling of a process for the supply of the volatile aromatic hydrocarbon, styrene, to a fermentor for increased biomass production of the medium chain length polyhydroxyalkanoate (mcl-PHA) accumulating bacterium Pseudomonas putida CA-3 was investigated. Fed-batch experiments were undertaken using different methods to provide the styrene. Initial experiments where styrene wa...
