The membrane filtration of lactic acid fermentation broth related to miso produciton was carried out using a hollow fiber membrane module. The effect of backwashing and/or bubbling operations on the filtration performance was examined. The following results were obtained : (1)The backwashing/bubbling operations were not so effective in maintaining a high filtration rate in the case of a dense cell broth, but were considerably effective for a lower cell concentration broth. (2)Bubbling after backwashing was more effective than employing both operatons at the same time. (3)There was an optimal applied pressure for the backwashing/bubbling operations. (4)Only backwashing si recommended, in order to simplify the operation and to prevent contamination;the effect of bubbling was not so significant compared with backwashing.
