Optimization of submerged culture conditions for the production of mycelial growth and exopolysaccharides (EPSs) by Collybia maculata was investigated. The optimum temperature and the initial pH for EPS production in a shake-flask culture of C. maculata were found to be 20°C and 5.5, respectively. Among the various medium’s constituents examined, glucose, Martone A-1, K2HPO4, and CaCl2 were the...

1 The present review roughly covers the publications that have appeared since Prof. K. Schügerl delivered a keynote address at the 4th GLS International Conference in 1997 (Schügerl, 1997). It includes publications that deal with gas/liquid systems without solids, but gives an extra weight to applications of airlift bioreactors to wastewater treatment and to algal growth. Three extensive review...

Abstract Therapeutic monoclonal antibodies (mAbs) are typically manufactured using mammalian cell cultures in fed‐batch bioreactors, with increasing emphasis on meeting productivity and product quality attribute targets that depend strongly such process variables as nutrient feed rates bioreactor operating conditions. In this article, we identify, categorize, address the challenges of achieving...

Unfortunately, author has missed to include the following text in Acknowledgement section "We also thank Dr Shaiful Azuar Mohamad and team from Nuclear Malaysia for providing mushroom polysaccharide (endo exo) samples 2018. Any future publications regarding provided should not be made without his consent." The updated complete is below:

Mixing has been one of the important parameters in characterizing and designing external air-lift bioreactors for the biological processes that require intensive mixing for mass transfer. In this study, pH tracer method was employed to characterize the mixing quality of a three-phase laboratory-scale external-loop air-lift bioreactor (EALR) used for cultivation of a pelletized filamentous funga...

A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...

Steady state and dynamic fermentations of baker's yeast in molasses based media were analyzed in a laboratory scale bioreactor. Sugar and biomass balances together with the Monod biokinetics were used to develop the process model. Parameters of the model were obtained using collected experimental data. Model predicted open loop responses to step changes in feed concentration as well as dilu...
