BACKGROUND Impactful greenhouse gas emissions abatement can now be achieved through gas fermentation using acetogenic microbes for the production of low-carbon fuels and chemicals. However, compared to traditional hosts like Escherichia coli or yeast, only basic genetic tools exist for gas-fermenting acetogens. To advance the process, a robust genetic(More)
This paper presents a system currently being developed for reliably recognising objects in a random orientation at video rates. The system uses an optical processor to produce the power spectrum on a CCD sensor and specialised digital hardware to sample the CCD output in the desired wedge ring geometry. The resulting system has a high throughput and at a(More)
