Abstract: A method for controlling at least one culture parameter in a bioreactor bag (1; 31 a, 31 b) provided in a bioreactor system, the method comprising the steps of: providing bioreactor information to a control unit (5; 35) controlling the bioreactor system; controlling the at least one culture parameter in dependence of the bioreactor information.

Abstract: A method for controlling at least one culture parameter in a bioreactor bag (1; 31a, 31b) provided in a bioreactor system, said method comprising the steps of: providing bioreactor information to a control unit (5; 35) controlling the bioreactor system; controlling the at least one culture parameter in dependence of the bioreactor information.

Abstract: An inflatable bioreactor bag for cell cultivation, which comprising a top and a bottom sheet of flexible material, joined together to form two end edges and two side edges, wherein one baffle or a plurality of baffles extend from the bottom sheet in a region where the shortest distance to any one of the two end edges is higher than about one fourth of the shortest distance between the two end edges.

Abstract: A method of cultivating cells in a bag is disclosed, which comprises the steps of: a) providing a sterile flexible bag comprising a filter material which is attached to a wall of the culture bag, wherein the filter material delimits a chamber inside the bag and wherein the chamber is fluidically connected to a first port in a wall of the bag, b) providing agitation means for the bag, c) introducing cell culture medium, microcarriers and cells to the bag, d) cultivating cells in the bag with agitation provided by the agitation means, allowing formation of a suspension of microcarriers with immobilized cells and supplying at least one gas via a second port (not shown) in a wall of the bag, e) removing cell debris and/or free cells together with liquid from said suspension of microcarriers through the filter material and the first port.
