Abstract
Summary
Three Chinese hamster cell lines (CHO-K1, V79, and CHS) were tested to see which carbohydrates would support their growth in culture. There were differences between lines (mannose supported growth of CHO-K1 only), and glucose was the only carbohydrate that supported growth of all three strains. CHO-K1 cells possess enzymes for hydrolyzing some disac-charides which do not support growth. Fetal calf serum contains enzymes that hydrolyze maltose, glycogen, and a-mannosides.
