Abstract. Dewiyanti I, Darmawi D, Muchlisin ZA, Helmi TZ, Arisa II, Rahmiati R, Destri E, Fanisha S. 2022. Characteristic and activity of cellulolytic bacteria isolated from mangrove soil in Northern Coast Aceh Province, Indonesia. Biodiversitas 23: 6587-6599. The as decomposing cellulose is related to the fertility productivity ecosystem, presence enzymes produced can evaluate them. study aims analyze characterization, cellulase enzyme activity, production molecular biology on northern coast This was conducted at six locations, samples were collected randomly with three replications. results showed that purified 39 isolates grew CMC selective media. common discovered have an irregular colony shape, undulate edge, raised elevation, cream pigmentation. bacilli cell most while 22 out activity. index (CI) ranged 0.31 4.82, highest CI BTM533 (4.82), followed by BTM622 (2.09). quantitative analysis specific 36 hours 42 value 0.042 U mg-1 0.129 mg-1. Among isolates, two high identified Bacillus safensis B. altitudinis using 16S rRNA gene molecularly.
