Latest Patents

One of Bjorn Welin's latest patents involves transgenic plants producing trehalose. This invention aims to increase the trehalose content of organisms by transforming them with two nucleotide sequences that encode different polypeptides found in yeast trehalose synthase. The patent details the isolation and cloning of these sequences, as well as a third polypeptide that has been characterized. The coding sequences can be inserted into suitable vectors to transform host cells, resulting in increased trehalose production compared to untransformed wild types. This innovation has the potential to improve the stress tolerance of organisms, extend the storage life of foodstuffs, and enable the economical production of trehalose on an industrial scale using traditional foodstuffs like baker's yeast.
