The mangrove ecosystem is an unexplored source for biotechnological applications. In this unique environment, endemic bacteria have the ability to thrive in the harsh environmental conditions (salinity and anaerobiosis), and act in the degradation of organic matter, promoting nutrient cycles. Thus, this study aimed to assess the cellulolytic activities of bacterial groups present in the sedimen...

Mangrove plantations can potentially restore the vegetation structures protecting coastal areas. In Avicennia alba in central Thailand, we investigated (trees, seedlings, pneumatophores, and belowground roots), sedimentation rates, elevation changes over one year across shore. The results showed a heterogeneous structure with an increasing tree basal area (BA) seedling density towards interior....

Sediment is an important part of heavy metal cycling in the coastal ecosystem, acting as a potential sink and source inorganic organic contaminants environmental conditions change. The productivity mangroves utterly dependent on sediment enrichment. Moreover, mangrove can trap pollutants discharged by households, industries, agriculture activities. In this regard, it essential to assess quality...

Microplastics are widespread in coastal and marine environments, sediments serve as a sink for microplastics. In this study, four sediment cores were collected from the Kuala Gula Mangrove area. The abundance of microplastics mangrove ranged 25–130 items/kg dry weight. highest microplastic was observed at KG04 site near mouth river. number by sampling significantly different (p < 0.01), with...

Abstract Through the role of phytase, some soil bacteria can mineralize insoluble organic P such as phytate (myoinositol hexakisphosphate). Phytase is a secreted enzyme possessing ability to hydrolyze into phosphate esters and inorganic for plants absorption. This study aimed isolate phytase-producing from mangrove sediment examine influence nutrients (source carbon, nitrogen, phosphorus) physi...
