A public-private team from RIKEN and Kaneka develops PHA production process based on lignin

Using Ralstonia eutropha H16 as a test organism, PHA was produced in a 2-step fermentation. In the first step, the organism was grown in a mineral medium containing vanillic acid, 4 – hydroxy benzoic acid (4-HBA), 2,5 – dihydroxybenzoic acid (2,5-DHBA) and other aromatic lignin degradation products. After shifting to richer culture conditions, the strain […]

Mitsubishi Electric Corporation develops better performing and less expensive radiation detector

In collaboration with a team from Kyushu University, Mitsubishi Electric has developed a counter for the separate measurement of Cs-134 and Cs-137 based on a novel signal restoration technology for the sodium iodide scintillator. A 2kg food sample can be measured in one minute with a detection limit of 25Bq/kg, one tenth compared to the […]
