CAZypedia celebrates the life of Senior Curator Emeritus Harry Gilbert, a true giant in the field, who passed away in September 2025.
CAZypedia needs your help!
We have many unassigned pages in need of Authors and Responsible Curators. See a page that's out-of-date and just needs a touch-up? - You are also welcome to become a CAZypedian. Here's how.
Scientists at all career stages, including students, are welcome to contribute.

Anne Tøndervik is a senior research scientist in the group of Biotechnology (headed by Håvard Sletta) at SINTEF Industry, Trondheim. She finished her PhD studies in procaryotic molecular biology (osmotic tolerance in bacteria) at NTNU in 2005 and has been working at SINTEF since 2008. The Biotechnology group has been collaborating closely with NOBIPOL at NTNU for many years on understanding the genetics of microbial alginate biosynthesis as well as establishing efficient production processes for microbial alginate. The work has also included engineering and activity screening of alginate modifying enzymes, and enzymatic tailoring of alginates for diverse applications.
