2.8. Statistical analyses
Experiments were conducted in triplicate with duplicate samples
analyzed at each sampling time. Treatment means and standard
deviation are reported. Data were analyzed using SAS (version
9.2) statistical package (SAS Institute Inc., Cary, NC.) for analysis of
variance (ANOVA) and the Bonferroni LSD method (Miller, 1981) to
estimate significant differences (p < 0.05) between mean values of
number of cells recovered after each treatment over the duration of
experiment. Any two means with no letter in common are significantly
(p < 0.05) different by the Bonferroni LSD method
