Diversity analysis among the total bacterial isolates (235) and within the l-asparaginase positive bacterial isolates (85)

Attributes	Total bacteria	Asparaginase positive bacteria
Richness (S)	43	15
Individuals (N)	235	85
Dominance (D)	0.116	0.377
Simpson diversity index (D1)	0.882	0.622
Shannon index (H′)	2.862	1.631
Evenness (e^H/S)	0.406	0.340

N number of individual bacteria identified, S number of genera based on 16S rDNA sequencing

H′ (Shannon index) = $-\sum \text{pi}ln(\text{pi})$, where pi is the proportion of isolate to genus I, E (Evenness index) = H/lnS

D (Dominance) = $\sum {\text{pi}}^2$, D1 (Simpson’s index) = $1-\sum {\text{pi}}^2$
