Cadmium (Cd) Reduction Bacteria From Northern Coast Sediment Indramayu, Indonesia

Cadmium (Cd) is one of the metals that contaminates Karangsong and has found several bacteria that can reduce cadmium (Cd). The purposes of this research are to obtain the type of bacteria and obtain an evolutionary relationship of cadmium (Cd) reduction bacteria from sediments in Karangsong Beach, Indramayu. The method used in this research is an exploratory method and the resulting data is analyzed descriptively. The molecular identification method uses 16S rRNA gene which is a universal primer for bacteria. The bacterial sequences obtained were analyzed with GenBank data from the NCBI website. The results showed that two bacterial isolates were identical to the Pseudoalteromonas issachenkonii strain KMM 3549 (Acc. No. NR 025139.1) with 77% identity value and 100% evolutionary relationship value and Pseudoalteromonas tetraodonis GFC strain IAM 14160 (Acc. No. NR 041787.1) with identity values 97% and evolutionary value 99%.
