Growth ofE. colicells bearing different clones from libraries. The growth (37°C, LB medium) of bacteria bearing a control clone 105–2 (diamonds), or clone 123–3 (squares) or 129–3 (triangles) from the cyanobacterial metagenomic library was monitored. Mean values from 3 independent experiments are shown with error bars indicating SD. Calculated generation times at the mid-exponential phase of growth were 36 min for bacteria bearing 105–2, 28 min for bacteria bearing 123–3, and 28 min for bacterial bearing 129–3.
