CO2 Fixation in Opuntia Roots

CO(2) Fixation in Opuntia Roots.

Nonautotrophic CO(2) metabolism in Opuntia echinocarpa roots was studied with techniques of manometry and radiometry. The roots were grown in a one-quarter strength nutrient solution for several days; the distal 2 cm was used for physiological studies. The roots assimilated significant quantities of (14)CO(2) and appeared to show a crassulacean-type acid metabolism with respect to quality and q...

Dark CO2 Fixation in Avocado Roots, Leaves, and Fruit

In a previous study avocado roots fixed CO2 about as rapidly as orange and lemon roots but much slower than bean roots (2). However, homogenates of avocado roots or leaves did not fix CO2. This study was made to explore reasons for the failure of homogenates of avocado to show CO2 fixation, and also to understand more of the relatively low degree of CO2 fixation by avocado roots in. case it may...

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

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 mass transfer equations for gas and liquid phases in the photobioreactor as well as thermodynamic equilibrium of inorganic carbon ions in the ...
