dc.description.abstractMicroorganisms play a crucial role in the biogeochemical cycling of organic matter through their heterotrophic activity. This study delves into comparing the sediment bacterial communities from the mangrove habitats of Chorao and Cortalim with terrestrial ecosystems of the Mhadhei and Netravali Forest areas of Goa. This provides an understanding of the bacterial community profiling based on 16S rRNA gene sequencing and their enzymatic potential in both habitats to delineate their differential potential in carbon remineralization and storage. The community structure revealed the varying bacterial communities and their functional profiles in the mineralization of organic matter from both habitats. The 62 bacterial morphotypes isolated were tested for their heterotrophic and carbonic anhydrase activity. The potential isolates, with maximum enzyme activity, were further used for microcosm study, to understand their ability to act on organic matter from mangrove and terrestrial habitats. The increased microbial activity in the terrestrial habitat with significant variation across both ecosystems based on ANOVA analysis underscores the influence of environmental conditions, substrate availability, bacterial community structure and its functional processes. Higher carbon passive pool, reduced liability index and lower microbial activity recorded in the mangrove habitat can be attributed to the long-term carbon storage in these ecosystems. This underscores the vital role of mangrove habitats as a significant blue carbon ecosystem, crucially contributing to climate change mitigation. These findings show the varying potential of sediment bacterial communities in carbon utilization and storage in the mangrove and terrestrial habitats.
