This article complements an earlier work published in 2015 Baron et al. (2015) that showed the interest of a shrimp shells bio-refining process. We compare here the effect of eleven commercial proteases at pH 3.5 or 4.0 on a residual amount of shrimp shells proteins after 6 h at 50 °C. The two pH are obtained when respectively 40 and 25 mmol of formic acid are added to 5 g of mild dried shell. ...

A yeast strain identified as Geotrichum sp. JR1 was able to use acetonitrile as the sole carbon and nitrogen source. The strain grew in 0.5 to 2M acetonitrile. Ammonia generation as enzymatic product during the strain growth indicates the presence of an acetonitrile degrading enzyme. Acetic acid and acetamide were detected during assays with the resting cells cultivated in acetonitrile, indicat...

To investigate conformational properties of an isolated n-octadecane chain solvated in water-acetonitrile mixtures, configurational-bias Monte Carlo simulations in the isobaric-isothermal ensemble were performed at T = 323 K and p = 10 atm. The united-atom version of the transferable potentials for phase equilibria force field was used to represent n-octadecane and acetonitrile, and the TIP-4P ...

The acetonitrile ligand in the title compound, [W(CH(3)CN)(CO)(5)], is coordinated end-on to a penta-carbonyl-tungsten(0) fragment with a W-N bond length of 2.186 (4) Å, completing an octa-hedral coordination environment around the W atom.
