    Enzymatic hydrolyses of chrome shaving waste from tannery through Aspergillus tamerii
    (Uludağ Üniversitesi, 2012) Kumar, Paramasivam Senthil; Sounderraj, Lesley; Sivakumar, Kandaswamy; Rajakumar, Suseela
    The isolated fungi were optimized and used in the production of enzyme (alkaline Proteases) by the Solid state fermentation. The enzyme extracted from the fungi was used in the hydrolysis of leather protein present in the chrome shaving waste and the recovered chromium was recycled and used in the tanning process. To completely hydrolyze 1 gram of leather wastes 6 unites of the enzyme protease is required. In the optimization, the fungi maximum production shows at 72 hrs, the nitrogenous source are the milk extract and the optimum temperature to hydrolyse is 55ºC and the pH is 9.5.
