    Enzymatic hydrolysis of sodium caseinate in a continuous ultrafiltration reactor using an inorganic membrane (1995)
    Springer
    Applied microbiology and biotechnology 42 (1995), S. 692-696 
    Details
    ISSN: 1432-0614
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Continuous hydrolysis of sodium caseinate by alcalase was investigated in a recycle bioreactor coupled to an inorganic M5 membrane module. The effects of various substrate concentrations and the role of an ultrafiltration membrane on conversion rate were reported. Although a high level of conversion was obtained in the retentate side at a steady state, only part of the products formed was transmitted through the inorganic membrane. Degree of hydrolysis and product concentration in the reactor seem to be the main factors limiting product output during the continuous hydrolysis.

    Tryptic hydrolysis of caseinomacropeptide in membrane reactor: Preparation of bioactive peptides (1992)
    Springer
    Biotechnology letters 14 (1992), S. 805-810 
    Details
    ISSN: 1573-6776
    Source: Springer Online Journal Archives 1860-2000
    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary Tryptic hydrolysis of caseinomacropeptide (CMP: C-terminal part of k-Casein) was used as a model in membrane reactor to study continuous production and isolation of bioactive peptides from milk proteins. Compared to the batch reactor, productivity of the proposed continuous process was 3 times higher after 3.5 hours of hydrolysis, but only 50% of the substrate is converted at steady state of the system. As shown by reverse-phase HPLC analysis, a good selectivity of the ultrafiltration membrane to various products was also obtained.

    Continuous hydrolysis ofβ-casein in a membrane reactor: Preparation of a bioactive peptide (1993)
    Springer
    Biotechnology letters 15 (1993), S. 697-702 
    Details
    ISSN: 1573-6776
    Source: Springer Online Journal Archives 1860-2000
    Topics: Process Engineering, Biotechnology, Nutrition Technology
    Notes: Summary Continuous Stirred Tank Membrane Reactor was used to investigate the continuous and selective extraction of a bioactive peptideβ-CN (193–209) from bovineβ-casein/chymosin hydrolysate. It was shown that the feasibility of the process depends on the nature and the area of ultrafiltration membrane used. With an inorganic (carbon-zirconia) membrane, high retention of the peptide constitutes a limit to the operation. However, when the reactor was equipped with a cellulosic type membrane, satisfactory transmission of the peptide was obtained. As shown by RP-HPLC and mass spectrometry analysis, onlyβ-CN (193–209) permeates through the membrane.
