Abstract

Large substrate hydrolysis of bulk water samples taken aboard the R/V Endeavor EN638, May 2019 in the Northern Atlantic.

Cite Dataset

The potential of the seawater microbial community to hydrolyze six high-molecular-weight polysaccharides (arabinogalactan, chondroitin sulfate, fucoidan, laminarin, pullulan, and xylan) was investigated in surface and bottom water. Seawater has been collected during the EN638 cruise on the R/V Endeavor in May 2019.
