Jean Archambault, Bohumill Volesky Wolfgang G.W. Kurz, ABSTRACT, A novel technique has been developed to immobilize plant cells. The cells are deposited on a surface of selected fibrous material which provides for strong binding of plant tissue biomass growing in the submerged culture. The immobilized plant cells remain fully viable. Relatively uniform biomass loadings of up to 20 mg d.w. of plant cells per cm2 of support material have been attained.

The development of laboratory size bioreactors using surface, …
