Biorefinery for a circular carbon paradigm: process benefits to the use of dryland CAM crops for anaerobic volatile fatty acid production.

Background: Anaerobic digestion (AD) or acidogenic fermentation (AF) of biomass can generate either biogas fuel or C ‒ C volatile fatty acids (VFAs) as feedstocks for synthesis of other petrochemical products. Typical AD feedstocks require large amounts of land that could otherwise be used for food production. Unlike these traditional bioenergy crops, plants using the crassulacean acid metabolism pathway (CAM), such as cacti and succulents, may be cultivated on degraded or semi-arid land that cannot support conventional agriculture.

The Pseudomonas syringae pv. actinidiae chemoreceptor protein F (PscF) periplasmic sensor domain: cloning, purification and X-ray crystallographic analysis.

Nitrate- and nitrite-sensing (NIT) domains are found associated with a wide variety of bacterial receptors, including chemoreceptors. However, the structure of a chemoreceptor-associated NIT domain has not yet been characterized. Recently, a chemoreceptor named PscF was identified from the plant pathogen Pseudomonas syringae pv.
