FIG. 4.

Viscosities of cell lysates. Nuclease-expressing and wild-type Pseudomonas sp. strain MBX978 were grown in fed-batch mode to a density of approximately 60 g/liter. Cell suspensions were subsequently homogenized with or without the addition of Benzonase. The viscosity of the lysate was determined as a function of the operating pressure of the homogenizer. Closed circles, Pseudomonas sp. strain MBX978 without added Benzonase; open circles, Pseudomonas sp. strain MBX978 with added Benzonase; closed squares, nuclease integrant Pseudomonas sp. strain MBX985 without added Benzonase.
