Abstract Pyruvic acid is an important organic and a key industrial raw material. It widely used in the chemical, agricultural, food fields. Candida glabrata preferred strain for pyruvic production. The waste yeast cell fermentation with C. are rich protein, amino acid, nucleic vitamins, as potential cost-effective nitrogen source In this study, of to produce using spent dry powder was evaluated...

In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitori...

Different control strategies of bed temperature and moisture were investigated using various inlet air temperatures and air fluxes in both the ordinary packed bed bioreactor (without cooling water in the jacket) and the bioreactor with cooling water in jacket. The experiments were carried out within a 1-L solid-state packed bed bioreactor in which Aspergillus niger was cultivated on wheat bran....

Failure to grow thick (3D) implantable bone tissue is partly due to the lack of tissue vascularisation resulting from a fall in nutrient supply to the cells as the distance between the cells and nutrient sources increases. Previous attempts that used porous scaffold without hollow fibre (HF) produced tissues of less than 0.5mm thickness which are of limited clinical use. Recent studies suggest ...
