Message-ID: <1014@bmc.uu.se> Date: 19 May 89 18:04:21 GMT Organization: Biomedical Center, University of Uppsala, Sweden Lines: 18 Does anybody know, whether E.coli strains (best would be K12) exist, that can live on cellobiose (4-{beta}-D-glucopyranosyl-D-glucopyranose) as the only carbon-source ??? Usually this is a test to exclude E.coli-strains, but perhaps... I would need them for cloning experiments. They would have several advantages when for example using a lac-promotor, as cellobiose might be cleaner than other available sugars and is finally a degradation product of cellulose, so that it might even become cheaper, when we use our natural sources more intense (in some future).
