Abstract
Organic extracts of different origin and various concentrations have
influence on the division rate as well as on the cellular products
content. Division rate and protein content has increased proportio-
nally to addition of yeast extract in 10 to 150% concentration. 
Division rate was stimulated by addition of mussel extract in 10
to 50% concentration. Protein synthesis is directly proportionally
to organic extract concentration. Our experiment has proved that
yeast extract has a stronger effect than mussel extract.
