Xanthan gum is a microbial polysaccharide of great commercial significance. This review
focuses on various aspects of xanthan production, including the producing organism …

In aerobic bioprocesses, oxygen is a key substrate; due to its low solubility in broths
(aqueous solutions), a continuous supply is needed. The oxygen transfer rate (OTR) must be …

In aerobic process oxygen must be continuously supplied in order to achieve acceptable
productivities, Since the role of oxygen in microorganism growth and its metabolism is of …

Using a strain-controlled rheometer, the steady shear flow properties of aqueous xanthan
gum solutions of different concentrations were measured over a wide range of shear rates …

Oxygen uptake rate and oxygen mass transfer rate have been studied during xanthan gum
production process in stirred tank bioreactor. Empirical equations for the oxygen mass …

A prediction method for calculating the volumetric mass transfer coefficient, kLa, in gas–
liquid sparged stirred tanks is proposed. A theoretical equation based on Hibie's penetration …

In this study, a miniature stirred tank bioreactor was designed for treatment of waste gas
containing benzene, toluene and xylene. Oxygen mass transfer characteristics for various …

Bacterial cellulose (BC) was produced by Acetobacter xylinum BPR 2001 and its acetan
nonproducing mutant EP1 in corn steep liquor-fructose medium in a 10-l jar fermentor …

Abstract Knowledge and prediction of mixing and mass transfer in agitated bioreactors is
fundamental for process development and scale up. In particular key process parameters …

Oxygen is the most essential requirement for aerobic bioprocesses. The microbial growth in
a bioreactor depends upon the oxygen transfer rate (OTR). The OTR is widely used to study …
