Different protein expression profiles in cheese and clinical isolates of Enterococcus faecalis revealed by proteomic analysis.

The use of Enterococcus faecalis in the food industry has come under dispute because of the pathogenic potential of some strains of this species. In this study, we have compared the secretome and whole-cell proteome of one food isolate (E. faecalis DISAV 1022) and one clinical isolate (E.

Catalytic properties of catechol 1,2-dioxygenase from Acinetobacter radioresistens S13 immobilized on nanosponges.

Catechol 1,2-dioxygenases are iron containing enzymes able to convert catechol into cis,cis-muconate, a precursor of the industrially important compound adipic acid. Catechol 1,2-dioxygenase from Acinetobacter radioresistens S13 was immobilized on beta-cyclodextrins cross-linked with carbonate groups (nanosponges) with a yield of 29 mg of enzyme per gram of support. This support was chosen for its low cost and its ability to offer different types of interactions with the enzyme.
