a
MIDcs are reported as the mean (standard error of the mean) in joules per square meter. Significant differences between mean UV-B+ and UV-B− MIDcs within a row were calculated using the Student t test and are as follows: A, P ≤ 0.05; B, P ≤ 0.01; C, P ≤ 0.001; NS, not significant, P > 0.05.
b
Includes 65 (UV-B+) and 46 (UV-B−) strains identified by FAME analysis.
c
Includes 132 (UV-B+) and 150 (UV-B−) strains identified by FAME analysis.
