TABLE 1 | Richness and diversity of microbial communities in marine sediment (MS) and phosphogypsum (PG) samples of Sfax (Tunisia), and in the sulfate-reducing enrichment cultures from MS (as inoculum) using sodium sulfate or phosphogypsum (PG) as sulfate
Figure 1). Interestingly, MS was dominated by only 8 OTUs
