Fig. 4From: An auto-inducible phosphate-controlled expression system of Bacillus licheniformisNorthern-blot analysis of the amyE gene expression of the B. licheniformis strain TH3 without (a) and with (b) 0.5 mM sodium phytate (added at an OD500 nm of 1.0). RNA samples were isolated from exponentially growing cells at an OD of 0.4 (1), at an OD of 1.0 (2) and 1, 2, 3 and 4 h after an OD of 1.0 (3, 4, 5 and 6). 10 μg of total RNA was used for each sampleBack to article page
