A soluble aldehyde dehydrogenase (EC 1.2.1.3) was partially purified from Rhizobium japonicum bacteroids and from free-living R. japonicum 61A76. The enzyme was activated by NAD+, NADH, and dithiothreitol, and it reduced NAD(P)+. Acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde, and succinic semialdehyde were substrates. The Km for straight-chain aldehydes decreased with increasing ca...

In previous communications from this laboratory on the fate of ethylene in avocados, it was shown that approximately 127, of the radioactivity of metabolized ethylene-3H appeared in the methyl group of toluene (1) whereas only approximately 0.2% of the radioactivity of metabolized ethylene-14C appeared in toluene (2). On the other hand, benzene produced by the metabolism of ethylene-3H and ethy...

Electroplating industry generatesharmful anionic heavy metalwhich is Hexavalent Chromium (Cr6+) that need to be treated before it can discharged into the environment following accordance Environmental Industry (Effluent Regulation) 2009. These Cr6+ ions must reduced chromium trivalent (Cr3+) using a reducing agent undergoing precipitation process for complete removal of (Chromium) Cr component....

Optimization of continuous synthesis of high purity carbon nanotubes (CNTs) using chemical vapour deposition (CVD) method was studied experimentally and theoretically. Iron pentacarbonyl (Fe(CO)5), acetylene (C2H...

feasibility of waste lime sludge (ls) obtained from acetylene gas production industry wasstudied during co-composting of vegetable waste for enhanced volatile solids reduction. four different trialswere carried out with varying percentage of ls combinations i.e. trial 1, trial 2, trial 3 and trial 4. increasedaddition of waste ls raised the levels of ph in the compost, thereby volatizing the ni...
