Anaerobic digestion of Crassulacean Acid Metabolism plants: Exploring alternative feedstocks for semi-arid lands

Feedstocks for Anaerobic Digestion (1998)

Exploiting the potential of plants with crassulacean acid metabolism for bioenergy production on marginal lands.

Crassulacean acid metabolism (CAM) is a photosynthetic adaptation that facilitates the uptake of CO(2) at night and thereby optimizes the water-use efficiency of carbon assimilation in plants growing in arid habitats. A number of CAM species have been exploited agronomically in marginal habitats, displaying annual above-ground productivities comparable with those of the most water-use efficient...

Update on Crassulacean Acid Metabolism Crassulacean Acid Metabolism. A Plastic Photosynthetic Adaptation to Arid Environments

Crassulacean acid metabolism (CAM) is an important elaboration of photosynthetic carbon fixation that allows chloroplast-containing cells to fix CO2 initially at night using phosphoenolpyruvate carboxylase (PEPC) in the cytosol. This leads to the formation of C4 organic acids (usually malate), which are stored in the vacuole. Subsequent daytime decarboxylation of these organic acids behind clos...

Synchronization of metabolic processes in plants with Crassulacean acid metabolism.

In plants with Crassulacean acid metabolism, a diel separation of carboxylation processes mediated by phosphoenolpyruvate carboxylase (PEPC) and Rubisco optimizes photosynthetic performance and carbon gain in potentially limiting environments. This review considers the mechanisms that synchronize the supply and demand for carbon whilst maintaining photosynthetic plasticity over the 24 h CAM cyc...
