Description Acceleration of wood weathering in the mangrove area is possible with the role of cellulolytic bacteria. Cellulolytic bacteria producing cellulase enzymes are needed by the animal feed and agriculture industries. Mangroves in Muntok Subdistrict undergo a process of adaptation to environmental changes due to tin mining, including microorganisms. Exploration of new species and strains of cellulolytic bacteria in miningaffected mangroves is needed to enrich the collection and its potential use for human needs. This study aims to identify cellulolytic bacteria in mangrove weathered wood in Muntok District, West Bangka Regency through isolation, screening, and biochemical characterization. Three sampling locations, namely Sukal Mangrove, Peltim Mangrove, and Tembelok Mangrove result 22 bacterial isolates with 11 isolates showing the ability of cellulose degradation in qualitative tests using Lugol. The biochemical characterization of bacterial isolates with the greatest cellulose degradation was directed towards Citrobacter freundii and Vibrio alginolyticus in samples of Sukal Mangrove and Actinomyces bovis in isolates from Peltim Mangrove.
Bakteri pada kayu lapuk diindikasikan memiliki kemampuan mendegradasi serat dan selulosa sehingga mempercepat pelapukan kayu yang berada pada wilayah mangrove. Mangrove pada daerah penambangan timah dimungkinkan memiliki kondisi berbeda dengan akibat pengaruh langsung maupun tidak langsung pertambangan timah di daratan dan lepas pantai. Pendegradasian selulosa bermanfaat pada peningkatan daya cerna limbah pertanian yang digunakan sebagai bahan baku pakan ikan. Penelitian ini bertujuan untuk mengidentifikasi isolat bakteri selulolitik dari kayu lapuk pada mangrove di Sungailiat, kabupaten Bangka dan Tukak Sadai, kabupaten Bangka Selatan melalui karaterisasi biokimia. Terdapat 13 isolat bakteri teridentifikasi sebagai bakteri selulolitik pada kedua lokasi mangrove. Uji biokimia pada isolat bakteri dengan daya degradasi selulosa terbesar mengindikasikan Bacillus pumilus pada mangrove Sungailiat dan Bacillus alvei pada mangrove Tukak Sadai.
