Influence of Vinasse Application in the Structure and Composition of the Bacterial Community of the Soil under Sugarcane Cultivation

Table 4

Diversity and richness rates observed for each bacterial community present in the soils analyzed. The results were based on 16S rRNA gene of the bacterial clones obtained from 4 environments.

	193	193	193	193
Evenness	0.98	0.97	0.97	0.97
Richness	0.93	0.76	0.83	0.85

Calculations were based on OTUs formation based on evolutionary distance of ≤ 0.03. Abbreviations are shown in Table 1. is number of OTUs observed. is sequences number. Evenness is / [44]. Richness is (number of OTUs singletons − 1)/. The observed value/maximum possible is informed. Maximum value observed for Shannon (). Confidence intervals (95%) for Chao 1. Maximum value observed for singletons.
