PCT No. PCT/BE91/00084 Sec. 371 Date May 20, 1993 Sec. 102(e) Date May 20, 1993 PCT Filed Nov. 28, 1991 PCT Pub. No. WO92/09681 PCT Pub. Date Jun. 11, 1992.Adherent or non-adherent microorganisms with or without microcarriers are cultured in an apparatus having rotatable planar trays that dip in and out of culture medium and momentarily retain culture medium due to rims along edges of the trays on both sides. The trays are in a housing that is substantially cylindrical and elongated along a longitudinal axis. The trays are arranged longitudinally to the longitudinal axis with spacing between the trays. The trays can be attached substantially radially to and around a shaft extending coaxially inside the housing, attached to both the shaft and the housing or attached to the housing without a shaft. Attachment is at one or two longitudinal edges of the trays. The shaft can be hollow and have a wall with openings. During culturing, the trays can be rotated in one direction 180 DEG and then rotated through 180 DEG in an opposite direction. |
