Mass Transfer, Light Pulsing and Hydrodynamic Stress Effects in Photobioreactor Development [PDF]

Chemical Engineering Transactions, 2015
Photobioreactor scalability involves multiple different interacting aspects including mass transfer, light pulsing and hydrodynamic stress. An efficient carbon dioxide supply and a frequent displacement of cells from poorly to highly illuminated zones is

Wastewater Biofilm Photosynthesis in Photobioreactors [PDF]

Microorganisms, 2019
Photosynthetic performance of algal-bacterial biofilms from an Italian wastewater treatment plant was studied in a flow-lane photobioreactor at different irradiances, temperatures, and flow regime to evaluate the effects of these environmental parameters

Integrated hybrid Nested-bottled photobioreactor for enhanced mixing, mass transfer, and CO₂ fixation in Arthrospira platensis raceway pond cultivation systems [PDF]

Biotechnology for Biofuels and Bioproducts
This study introduces a novel hybrid photobioreactor system that integrates an open raceway pond (ORWP) with a Nested-bottled photobioreactor (NB-PBR) in a closed-loop configuration to enhance microalgal biomass production and CO₂ fixation.

Toward Sustainability: Intensification of Light-Driven Whole Cell Biocatalysis. [PDF]

Chembiochem
Whole‐cell, light‐driven biotransformations in photoautotrophic microorganisms offer the potential for higher atom economy by directly harnessing reducing equivalents and oxygen generated through natural photosynthesis. Current advances include the development of strains with improved growth rates and reactor designs that mitigate self‐shading ...

Experimental Study and Numerical Modeling of CO2 Bio-Fixation in a Continues Photobioreactor [PDF]

Journal of Chemical and Petroleum Engineering, 2020
A dynamic numerical model was developed to predict the biomass concentration, pH, and carbon dioxide fixation rate in the continuous culture of cyanobacteria in a photobioreactor. The model is based on the growth rate equation of microalgae combined with
