Abstract: Multi-stage, biological processes and systems for converting a C1 carbon source to desired end products are described. The processes comprise dividing a gaseous C1-containing substrate, in parallel, among multiple bioreactor stages. Liquid products are successively fed, in series, from a first bioreactor stage to downstream bioreactor stages. Operation can be simplified by avoiding the requirement for microorganism separation and recycle at each stage. In addition, overall vapor-liquid mass transfer for the combined stages is very favorable, leading to high end product productivity with comparably low byproduct metabolite productivity.

Abstract: An accurate and robust wavefront-division polarimetric analysis method and device, allows the quasi-instantaneous measurement of the polarization states of a luminous object. The device can be used to produce a plurality of light beams, all polarized according to different polarization states, from a single upstream light beam. The polarized light beams, which do not overlap and which carry information items that are complementary in terms of polarization, are analyzed simultaneously by a plurality of detectors that measure the luminous intensity of each beam. Processing elements digitally process the luminous intensity values obtained in order to determine the polarization state of the upstream light beam. The operations performed by the processing elements prevent luminous intensity variations in the split light beams during the division of the wavefront of the upstream light beam.
