“…The general chemical composition of different mangrove species was reported in our earlier study, which are summarized in Table 1 (Mun et al 2011). The extractives content [as determined by sequential extraction with dichloromethane followed by methanol/water (1:2, v/v)] was quite high when compared with that of other hardwoods (Sjöstrom 1993).…”

“…Therefore, the objective of this paper was to characterize morphological and physical properties of six important mangrove species in Bangladesh like Keora (Sonneratia apetala), Gewa (Excoecaria agallocha), Bine (Avicennia alba), Sundari (Heritiera fomes) Pashur (Xylocarpous mekongests) and kakra (Bruguiera gymnorhiza), and chemical characteristics of these six species were also discussed from our previously published data (Mun et al 2011). The pulping and papermaking properties of these six mangrove species were also carried out.…”

In this paper, physical, morphological and chemical characterizations of the six main mangrove species of Bangladesh [namely Keora (Sonneratia apetala), Gewa (Excoecaria agallocha), Bine (Avicennia alba), Sundari (Heritiera fomes) Pashur (Xylocarpous mekongests) and Kakra (Bruguiera gymnorhiza)] were discussed in order to assess the suitability of pulping raw materials. The wood density of these six mangrove was found to be 0.5-0.6 g cm -3 except Gewa which had 0.39 g cm -3 . The fiber length of these species was varied from 0.74 to 1.2 mm that was considered as short fiber. Sundari contributed the longest fibre length (1.2 mm) among these six species. The chemical results revealed that these species contain high percentages of dichloromethane, followed by methanol extractives. Methanol extracts in Pashur, Sundari and Bine was higher than 10 %, which indicates high percentage of tannin material. These species were characterized with high lignin content and low a-cellulose content. The pulping of these six mangrove species was also carried out by kraft process and papermaking properties were also evaluated. Pulp yield was lower and kappa number was higher as compared with other tropical hardwoods. But the physical properties of these species were quite acceptable. Considering pulp yield, kappa number and physical properties, it may be concluded that Keora and Gewa can be used as kraft liner and other packaging grade paper pulp.

“…The soil samples were likely rich in mangrove lignin due to the decayed mangrove plant litters. A previous report showed that several mangrove plants had higher total lignin content than that of other plants [ 26 ]. Moreover, the mangrove wetland soils have been impacted by chronic chemical and dyestuff contaminations from anthropogenic activities, as mentioned above in the “Introduction” section.…”

“…The source of lignin can be of plant origin that represents a significant part of plant litters input into the soil [ 25 ]. A previous report showed that there were four mangrove plants that had total lignin content more than that of the normal range of hardwood [ 26 ]. Moreover, mangrove soil is considered as a natural pollution trap for dyestuffs and related chemicals released from local communities, community enterprises and dye-utilizing industries.…”

Wastewater released from textile and dye-based industries is one of the major concerns for human and aquatic beings. Biological decolorization using ligninolytic bacteria has been considered as an effective and alternative approach for the treatment of dyeing wastewater. This study aimed to assess the isolation, characterization and application of soil bacteria isolated from mangrove wetlands in Thailand. Four active bacteria were genetically identified and designated as Klebsiella pneumoniae strain RY10302, Enterobacter sp. strain RY10402, Enterobacter sp. strain RY11902 and Enterobacter sp. strain RY11903. They were observed for ligninolytic activity and decolorization of nine reactive dyes under experimental conditions. All bacteria exhibited strong decolorization efficiency within 72 h of incubation at 0.01% (w/v) of reactive dyes. The decolorization percentage varied from 20% (C.I. Reactive Red 195 decolorized by K. pneumoniae strain RY10302) to 92% (C.I. Reactive Blue 194 decolorized by Enterobacter sp. strain RY11902) in the case of bacterial monoculture, whereas the decolorization percentage for a mixed culture of four bacteria varied from 58% (C.I. Reactive Blue 19) to 94% (C.I. Reactive Black 1). These findings confer the possibility of using these bacteria for the biological decolorization of dyeing wastewater.

“…In the present study, both grapsid crabs consumed a higher proportion of plant fragments in S. apetala plantations than they did in two native forests in summer, when foods were adequate (Figure 3), most likely because lower leaf nitrogen content was found in S. apetala leaves compared to native mangrove leaves (unpublished data). Also, the lower concentration of tannin and cellulose in S. apetata fragments would make them more palatable, again when compared to the two native mangrove species (Mun et al, 2011;Wang et al, 2014).…”

The macrozoobenthos is an important link of the food web in coastal wetlands. Diet-habitat relationships may significantly depend on qualitative differences and seasonal availability of food sources. Increasing interest has been shown in food web structure altered by non-native plants. In particular, however, a non-native mangrove species from Bangladesh, Sonneratia apetala, has been widely planted in China, but little is known about its possible impact on food sources of macrozoobenthos living in these non-native mangrove forests. Therefore, in this study, we used fatty acid analysis to compare the food sources of one littorinid snail and two grapsid crab species between two native mangrove forests and one non-native S. apetala plantation in the Zhanjiang Mangrove National Nature Reserve of China. We found that the sediment of all three forests had high diatom and bacteria signals, but low mangrove leaf signals, while the opposite patterns were detected in the three macrozoobenthos. Specifically, the gastropod Littoraria melanostoma relied mainly on mangrove leaves and brown algae as food sources, with significant differences among the three mangrove forests, and showed significant seasonal variation in its diet. The grapsidae species (Perisesarma bidens and Parasesarma plicatum) mainly grazed on mangrove litter, brown and green algae, and occasionally consumed diatoms and bacteria, also showing significant seasonal variation in their diet.
