We have designed a unique strategy to obtain a zinc-salen functionalized porous polymer (Zn@SBMMP) with high zinc content (15.3 wt%) by an easy one-step, cost effective and scalable process, which shows unprecedented catalytic efficiency in the CO2 fixation reaction via cycloaddition of CO2 with epoxides. We hypothesize that a high density of Zn-Schiff base/salen units present in the porous pol...

Redox regulation of chloroplast enzymes via disulphide reduction is believed to control the rates of CO2 fixation. The study of the thioredoxin reduction pathways and of various target enzymes lead to the following guidelines.

The effect of 3,3-dichloro-2-(dihydroxyphosphinoylmethyl)propenoate (DCDP), an analog of phosphoenolpyruvate (PEP), on PEP carboxylase activity in crude leaf extracts and on photosynthesis of excised leaves was examined. DCDP is an effective inhibitor of PEP carboxylase from Zea mays or Pancum miliaceum; 50% inhibition was obtained at 70 or 350 micromolar, respectively, in the presence of I mil...

In order to set a reference inventory data, an extensive literature search on compost production and compost utilization has been performed. The aim is to define carbon and energy footprint of bio-waste recycling and compost utilization. The available data suggest that when bio-waste is properly collected and recycled (through composting or anaerobic digestion) and a high quality compost is pro...
