“…In our study, the Cu concentrations in both statins were much higher than the NOAA guidelines [ 48 ] and the ASV value of Turekian and Wedepohl [ 36 ]. Moreover, this finding of Cu concentration was higher than mangrove sediments in Kerala mangrove ecosystem [ 49 ], Pichavaram mangrove forest [ 50 ], Mahanadi delta mangrove area [ 51 ], Indian Sundarbans [ 25 ] and previous findings from Mongla area [ 26 ]. The higher level of Cu in the study area might be the result of anthropogenic activities such as vehicle and coal combustion emissions, car lubricants and natural phenomenon such as metal contents of rocks and parent materials, processes of soil formation [ 26 ].…”

Toxic metal pollution is a global issue, and the use of metal-accumulating plants to clean contaminated ecosystems is one of the most rapidly growing ecologically beneficial and cost-effective technologies. In this study, samples of sediment and three mangrove species (Excoecaria agallocha, Avicennia officinalis, Sonneratia apetala) were collected from the world’s largest mangrove forest (along the Northern Bay of Bengal Coast) with the aim of evaluating metal concentrations, contamination degrees, and phytoremediation potentiality of those plants. Overall, the heavy metals concentration in sediment ranged from Cu: 72.41–95.89 mg/kg; Zn: 51.28–71.20 mg/kg; Fe: 22,760–27,470 mg/kg; Mn: 80.37–116.37 mg/kg; Sr: 167.92–221.44 mg/kg. In mangrove plants, the mean concentrations were in the order of E. agallocha > A. officinalis > S. apetala. The mean (± SD) concentration of each metal in the plant tissue (root) was found following the descending order of Fe (737.37 ± 153.06) > Mn (151.13 ± 34.26) > Sr (20.98 ± 6.97) > Cu (16.12 ± 4.34) > Zn (11.3 ± 2.39) mg/kg, whereas, in the leaf part, the mean concentration (mg/kg) of each metal found in the order of Fe (598.75 ± 410.65) > Mn (297.27 ± 148.11) > Sr (21.40 ± 8.71) > Cu (14.25 ± 2.51) > Zn (12.56 ± 2.13). The contamination factor (CF) values for the studied metals were in the descending order of Cu > Sr > Zn > Fe > Mn. The values of Igeo (Geo-accumulation index) and CF showed that the area was unpolluted to moderately polluted by Zn, Fe, Mn, Cu and Sr. Enrichment factor (EF) values in both sampling stations portrayed moderate to minimum enrichment. Phytoremediation potentiality of the species was assessed by bio-concentration factor (BCF) and translocation factor (TF). BCF values showed less accumulation for most of the heavy metals (<1) except Mn which was highly accumulated in all mangrove plants. The translocation factor (TF) values depicted that most of the heavy metals were strongly accumulated in plant tissues (>1). However, the BCF value depicts that Mn was highly bioconcentrated in E. agallocha, but the translocation on leaves tissue were minimum, which reveals that E. agallocha is phytoextractor for Mn, and accumulated in root tissues. All the examined plants can be used as phytoextractors as they have bioconcentration factors <1 and translocation factors >1. However, A. officinalis is clearly more suitable for metal extraction than S. apetala and E. agallocha in terms of hyper-metabolizing capabilities.

“…Ramamurthy et al, (2012) observed water temperature in the range of 26 to 28oC at the Vedaranyam mangrove forest. Behera et al, (2008) The pH values were varied from 7.4 to 8.1, high pH recorded during the summer season, greater photosynthetic activity whereas, the low pH values observed during monsoon and post-monsoon seasons might be due to decomposition of organic matter, which on biological oxidation gives up 'carbon dioxide' (Upadhyay, 1988;Rajasegar 2003 andSaravanakumar et al, 2008). Ramanathan et al, (1999) found pH in the range of 7.71 -7.82 while working on Pichavaram mangroves.…”

“…Recently, halophilic microorganisms, especially bacteria, have attracted the attention of many researchers to find novel enzyme sources, since these could be relatively more stable and active than other enzymes derived from plants or animals [ 38 , 39 ]. Previous studies have reported many bacterial strains originated from mangrove environments, such as soils ([ [40] , [41] , [42] ]), endosphere [ 43 ], and rhizosphere [ 44 ]. However, the present study was focused on isolating bacteria from mangrove in different soils depth (10, 20, and 30 cm) and associated with some insects that inhabit the same area of the mangrove tree.…”

“…Mangrove sediments play an important role as physical substrates and nutritional sources in mangrove ecosystems. Biochemical processes occurring in mangrove forests are especially from upper sediments, including oxidation processes and plant-soil interactions ([ 40 , 41 ]). Bacteria are involved in the process of P (phosphate) transformation in soil sediments and become an important part of the soil P cycle.…”

Highlights Bruguiera cylindrica is a mangrove plant in North Sumatra with limited information on its microbial endophytes. An enzyme bioprospection study was conducted revealing Vibrio alginolyticus as a prominent proteolytic strain. Vibrio alginolyticus Jme3-20 produced a multitude of extracellular enzymes such as amylase, cellulase, chitinase, phosphatase, and urease. This is the first report on finding Vibrio alginolyticus from mangrove area of North Sumatra.
