In tissue engineering, bioreactors can be used to aid in the in vitro development of new tissue by providing biochemical and physical regulatory signals to cells and encouraging them to undergo differentiation and/or to produce extracellular matrix prior to in vivo implantation. This study examined the effect of short term flow perfusion bioreactor culture, prior to long-term static culture, on...

This is the first study to examine effect of three different cultivation methods (bottom-tray culture, suspended-tray and beach/bottom culture) on growth survival rates snout otter clam, Lutraria philippinarum, after 12 months grow-out from seed commercial size. Analyses included weight, survival, shell size, total fat. Although results showed limited differences in among methods, were signific...

Introduction. We describe a continuous modelling and simulation framework aimed at monitoring and steering a recently developed bioreactor for cartilage production based on mesenchymal stem cells (MSCs). This bioreactor provides online-access to the cell density by acoustic measuring sections. An appropriate oxygen distribution throughout the bioreactor is essential for a successful expansion a...

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....

The three dimensional (3D) cultivation of stem cells in dynamic bioreactor systems is essential in the context of regenerative medicine. Still, there is a lack of bioreactor systems that allow the cultivation of multiple independent samples under different conditions while ensuring comprehensive control over the mechanical environment. Therefore, we developed a miniaturized, parallelizable perf...

Supplementation of mesenchymal stem cells (MSCs) during hematopoietic stem cell (HSC) transplantation alleviates complications such as graft-versus-host disease, leading to a speedy recovery of hematopoiesis. To meet this clinical demand, a fast MSC expansion method is required. In the present study, we examined the feasibility of using a rotary bioreactor system to expand MSCs from isolated bo...

Anaerobic biological wastewater treatment has numerous advantages over conventional aerobic processes; anaerobic biotechnologies, however, still have a reputation for low-quality effluents and operational instabilities. In this study, anaerobic bioreactors were augmented with an oxygen-transferring membrane to improve treatment performance. Two anaerobic bioreactors were fed a synthetic high-st...
