Título Marine bacteria can extract all phosphate from seawater using positive charge of their cell membrane Nome/saída de meios de comunicação Diamond Light Source Tipo de meios de comunicação Web País/Território United Kingdom Data 27/10/20 Descrição Scientists have discovered how the most abundant marine bacteria – fundamental to life on Earth – can extract all phosphate from seawater using positive charge of their cell membrane.
The findings, which have been published in Nature Communications, show how a bacterial cell enveloped in two layers of membrane uses its energetic capacity to positively charge the inner membrane in order to extract negatively-charged phosphate from seawater. The acquired phosphate is then stocked inside the bacterial “skin” - the periplasmic space between the outer and inner membranes. This is contrary to long-held view that bacteria acquire phosphate by keeping the periplasmic space void of phosphate to make it diffuse from the outside.URL https://www.diamond.ac.uk/Science/Research/Highlights/2020/Marine-bacteria-can-extract-all-phosphate-from-seawater-using-positive-charge-of-their-cell-membrane.html Pessoas Mikhail Zubkov
