Enzymes of poly-beta-hydroxybutyrate metabolism in soybean and chickpea bacteroids
Article Abstract:
The differences in the activities of enzymes involved in poly-beta-hydroxybutyrate (PHB) metabolism are responsible for the greater accumulation of PHB in soybean as compared to chickpea bacteroids. However, in free-living cultures the chickpea bacteroids expresses all the enzymes necessary for PHB synthesis, and accumulate large amounts of PHB. The greater potential for the oxidation of malate to oxaloacetate in the chickpea bacteroid leads to the greater utilization of acetyl-coenzyme A in the tricarboxylic acid as compared to PHB synthesis.

Microbial consumption of atmospheric isoprene in a temperate forest soil
Article Abstract:
A study was conducted on isoprene consumption by soil microorganisms in a temperate forest soil using both in situ and in vitro techniques. Experiments revealed that isoprene loss stems from biological processes which confirm that consumption ceases by autoclaving the soil and that consumption rates increase with constant exposure to isoprene. Furthermore, microorganisms consume isoprene even at trace-level concentrations and that soil microorganisms provide a biological sink for atmospheric isoprene.
