The deep biosphere contains a large portion of the total microbial communities on Earth. but little is known about the carbon sources that support deep life. In this study. we used Stable Isotope Probing (SIP) and high throughput amplicon sequencing to identify the acetate assimilating microbial communities at 2260 m depth in the bedrock of Outokumpu. https://parisnaturalfoodes.shop/product-category/org-hard-unbleached-bread-flour/
