Chemically modified "polar patch" mutants of subtilisin in peptide synthesis with remarkably broad substrate acceptance: designing combinatorial biocatalysts. by Matsumoto, K, Davis, B, Jones, J

“…Such wide-ranging systems displaying broadened and therefore similarly high, balanced yields of products (e.g. 91 % Z-L-Ala-GlyNH(2) and 86 % yield of Z-D-Ala-GlyNH(2) using S166C-S-(3R,4S)-indenooxazolidinone) may now allow the use of biocatalysts in parallel library synthesis.…”

Candida rugosa lipase imobilization on modified mesoporous kit-6 from rice husk as biocatalyst in esterification for butyl butyrate by Golbaha, Noorulsyahidaini

“…Lipases as are widely exploited in various industries, especially in the food processing industries for their ability to act on a variety of substrates, pH and thermal stability, resistance to solvents, and they are also highly specific as chemo-, regio-, and enantioselective biocatalysts. However, enzymes have serious drawbacks such as, often unstable in the long term operation, high cost and non-reusability. …”

The study on the use of a biocatalyst based on Calcined Cow Teeth-TiO2 composite in degrading the methylene blue dye by Khalil EL Abbadi, Fatine Echabbi, Younes Ouzidan, Amina Khalidi-Idrissi, Rajae Lakhmiri, Mohamed Safi

“…In this work, from a simple deposition and calcination process, a Cow Teeth composite CCT-TiO2 was fabricated using Calcined Cow Teeth as a template and employed as a biocatalyst to remove a specific target dye from an aqueous solution under UV irradiation.The composite, CCT-TiO2, with a dosage of (0.2 g/L), at room temperature and a 3 h treatment time under UV light, showed a positive behavior towards the photochemical degradation of Methylene Blue (C = 0.01 g/L) mainly in a basic medium pH = 8 giving a catalytic efficiency rate up to 98%.The main parameters affecting the efficiency of the photocatalytic treatment, such as pH, the mass of catalyst added to the solution, the percentage of TiO2 in the composite, the concentration of MB at the beginning, the presence of ethanol, the addition of hydrogen peroxide and the temperature were studied to evaluate their influence on the degradation of methylene blue.The photodegradation performance is inversely proportional to the initial dye concentration. …”
