Tait and Havenhand Biofilm data

Biofilms data.txt: This data records the number of Balanus improvisus cyprids exploring (Day 2 data only) and the number of cyprids settled (Days 3 to 7 data) on biofilms of signal-producing and signal-deficient biofilms. Biofilms either had mutations to their AHL synthase gene or were expressing the recombinant AHL inactivation protein AiiA. The biofilms were: Vibrio anguillarum NB10, a vanM mutant of this strain, and a variant expressing aiiA; A. hydrophila and an ahylI mutant and Sulfitobacter sp. BR1 and a sulI mutant. Each experiment also contained no biofilm controls. Experiments with V. anguillarum were conducted with 3 batches of cyprids, Sulfitobacter BR1 with 2 batches of cyprids and A. hydrophila with 1 batch of cyprids. This data was recorded by Karen Tait, Plymouth Marine Laboratory (ktait@pml.ac.uk) at the Department of Biological and Environmental Sciences, Tjarno, Sweden in June 2009. Column headings: V. anguillarum Batch 1; V. anguillarum Batch 2; V. anguillarum Batch 3; A. hydrophila Batch 1; Sulfitobacter Batch 1; Sulfitobacter Batch 2. Sub-headings: Biofilm Type (WT, mutant or no biofilm); Vessel No.; Day 2 (percent number of cyprids actively exploring biofilm); Day 3 (percent number of cyprids settled); Day 4 (percent number of cyprids settled); Day 5 (percent number of cyprids settled); Day 6 (percent number of cyprids settled); Day 7 (percent number of cyprids settled). Mutant biofilm descriptions are as follows: vanM – V. anguillarum, mutation to the AHL synthase, vanM; aiiA – V. anguillarum expressing the AHL degradation protein AiiA; ahyI – A. hydrophila, mutation to the AHL synthase, ahyl; sulI – Sulfitobacter BR1, mutation to the AHL synthase, sulI
