Studio della subunità epsilon della DNA polimerasi III di Escherichia coli: stabilità e interazione con la subunità polimerasica
… of ε. Two α-helices (comprising the residues E311-M335 and G339-D353, respectively) of the N-terminal region of the polymerase subunit were shown to be essential for the binding to ε. These informations could be utilized to produce a conditional mutator strain in which proofreading activity …

Processi di biorefining per l'estrazione di secondary chemical building blocks da sottoprotti dell'agro-industria
Phenol and cresols represent a good example of primary chemical building blocks of which 2.8 million tons are currently produced in Europe each year. Currently, these primary phenolic building blocks are produced by refining processes from fossil hydrocarbons: 5% of the world-wide production comes …

NON-CONVENTIONAL YEASTS AS CELL FACTORIES: FROM FOOD WASTE TO ADDED-VALUE PRODUCTS.
In the context of circular economy and green chemistry, non-conventional yeasts are known as efficient ‘cell factories’ for the synthesis of value-added products. The incorporation of industrial food waste in fermentation and biocatalytic processes is one of the major challenges in the transition …
