The water retention curve deduced with low content data allows the modelling of bentonite void ratio associated pores located inside clay aggregates, or micropores. However, if both and microporosity continue to increase, latter can no longer be directly obtained from former, because, in that case, presence existing between aggregates (macropores) may not negligible. Therefore, it is easy obtai...

In the coming years, the frequency of unauthorised genetically modified organisms (GMOs) being present in the European food and feed chain will increase significantly. Therefore, we have developed a strategy to identify unauthorised GMOs containing a pCAMBIA family vector, frequently present in transgenic plants. This integrated approach is performed in two successive steps on Bt rice grains. F...

The rapid increase in the number of genetically modified (GM) varieties has led to a demand for high-throughput methods to detect genetically modified organisms (GMOs). We describe a new dynamic array-based high throughput method to simultaneously detect 48 targets in 48 samples on a Fludigm system. The test targets included species-specific genes, common screening elements, most of the Chinese...

Two new 5-oxomilbemycins, 27-aldehyde-5-oxomilbemycin β12 (1) and 2-hydroxymilbemycin K (2), were isolated from a genetically engineered strain Streptomyces bingchenggensis BCJ60. Their structures were determined by comprehensive analyses of its 1 H and 13 C NMR, COSY, HMQC, and HMBC spectroscopic, HRESI-MS mass spectrometric and comparison with data from the literature. Preliminary studies sho...
