Chemical analyses of grape pomace revealed the presence of significant amounts of fermentable sugars that are retained in the pomace after pressing of the grapes. Furthermore, treatment of the pomace with purified hydrolases indicated that the enzyma

Eutectic freeze crystallization (EFC) separates aqueous inorganic solutions into pure water and pure salt. By operating at the eutectic point, ice and salt can be formed simultaneously as two separate phases. The scraped cooled wall crystallizer (SCW

The culture supernatant of Thermomyces lanuginosus strains MED 2D and MED 4B1 had high activities of xylanase with low inducible activities of β-xylosidase. The crude xylanase was optimally active at 70 °C and at pH 6.0 to 6.5. Subsequently Eucalyp

Using fungi grown on synthetic agar medium, we evaluated and compared the concentration of various H2O2-producing enzymes. Our results showed that oxidase production in solid medium was better than that found in liquid medium and as high as that dete
