Abstract:
In the recent years the development of genomics and introduced new techniques and greater possibilities in the study of microbial diversity in the environment. The present research was done on bacterial diversity in water samples from Great man-made river in Libya by using Metagenomics, new technology in the world of genetic engineering field. DNA sequences or phylogenetic analysis depended on a single gene, the 16S small subunit ribosomal RNA (rRNA) gene. DNA nucleotide sequence were analyzed with 16s r RNA by BLAST and phylogenetic tree to obtained the relation between types of bacterial sequence get in the present study. The first sequence CG20160324A shows similarity to Staphylococcus saprophyticus., Second sequence CG20160324B shows similarity to Vibrio vulnificus strain NBRC 15645, Third sequence CG20160324C shows similarity to Streptococcus pyogenes strain-1-273 and Four sequence CG20160324AD shows similarity to Aeromonas salmonicida. This diversity study proves that All the species identified shows toxic characters.
