Understanding microbial syngas fermentation rates

Applied Microbiology and Biotechnology
Syngas fermentation to ethanol has reached industrial production. Further improvement of this process would be aided by quantitative understanding of the influence of imposed reaction conditions on the fermentation performance. That requires a reliable model of the microbial kinetics.

Multi-fidelity Bayesian Optimisation of Syngas Fermentation Simulators

CoRR, 2023
A Bayesian optimization approach for maximizing the gas conversion rate in an industrial-scale bioreactor for syngas fermentation is presented. We have access to a high-fidelity, computational fluid dynamic (CFD) reactor model and a low-fidelity ideal-mixing-based reactor model. The goal is to maximize the gas conversion rate, with respect to the input

Dry Reforming of Biogas Over Li–Ni–Al Catalysts: Influence of Li Incorporation Method

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Hydrogen is a promising source of energy, given the current context of depletion of fossil fuels and increased emissions of greenhouse gases. The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH4 and CO2 into synthesis gas ...

Nutrient composition and heavy metal accumulation in water hyacinth [Eichhornia crassipes (Mart.) Solms] and water lettuce (Pistia stratiotes L.) from the Dande River, Nepal: Implications for use as alternative feed resources

JSFA reports, EarlyView.
Abstract Background The proliferation of invasive aquatic macrophytes poses a significant ecological challenge globally, while many tropical regions face chronic shortages of affordable livestock feed. This study addresses this dual problem by assessing two invasive species, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes ...
