Proposed membrane bioreactor is in line with the recent biotechnological developments through a series of
specific characteristics: continuous flow operation, allows high pressure variations due to component
geometry is modular, it can be adapted for large productions. Conditions of energy use is much lower due
to pressure generated by the accumulation of gases produced by microorganisms.DFs from barley, triticale,
oat and wheat. The obtained value of the regression coefficient was r = 0.917.
