Monitoring management criterion of an anaerobic digester using an explicit model based on temperature and pH [PDF]
arXiv, 2017 In this paper, the stability analysis of an anaerobic digestion process is presented. The analysis is performed using a simplified mathematical model, which includes explicit temperature and pH dependence on kinetic growth rates. A detailed nonlinear and bifurcation analyses are performed in order to study the effects of temperature and pH parameters ...

Journal of Applied Polymer Science, EarlyView.ABSTRACT Cardiovascular diseases are one of the leading causes of global mortality. Treatment methods such as bypass graft operations, while often successful, can fail in cases of systemic disease or compliance mismatch. Tissue engineered vascular grafts may offer a potential solution, by means of an implantable cell‐seeded scaffold that can integrate ...

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Actinobacillus succinogenes is a ruminal microorganism of biotechnological importance due to its capacity to produce succinic acid at high yields. Despite the scientific interest in this organism, molecular vehicles for the transfer and expression of genetic material are limited compared to the existing demand.

Influence of oxygen concentration on the metabolism of Penicillium chrysogenum
Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract In large‐scale bioreactors, there is often insufficient mixing and as a consequence, cells experience uneven substrate and oxygen levels that influence product formation. In this study, the influence of dissolved oxygen (DO) gradients on the primary and secondary metabolism of a high producing industrial strain of Penicillium chrysogenum was ...
