Studying microbial diversity in some soil samples typical agricultural cultivation and collection from the Dong Thap Muoi region

Abstract

This study aims to survey the research components and diversity of soil microorganisms in the Dong Thap Muoi region. Soil samples collected from three provinces Long An, Dong Thap and Tien Giang during the period from June to December 2022. The results showed the diversity of microorganisms in the soil samples, with sample DT3 (at Thuong Lac commune, Hong Ngu district, Dong Thap province) is the rice growing area with the highest density of bacteria, actinomycetes and fungi. Metagenomics analysis shows that archaea account for 5.7%, including 6 phylum, 11 classes, 17 prders, 21 families and 24 genera. Residential micro-areas use the largest proportion with 94.3%, including 33 branches, 90 classes, 161 orders, 300 families and 587 branches. The subdivision is defined as 11 phylum, 32 classes, 67 orders, 131 families, 185 genera and 230 groups of the Kingdom of Fungi.
