Title Marine bacteria can extract all phosphate from seawater using positive charge of their cell membrane Media name/outlet Diamond Light Source Media type Web Country/Territory United Kingdom Date 27/10/20 Description 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.
