“…pH value of sediment samples presented the alkaline condition [22]. pH values results were similar with previous studies on sediment characteristics of mangrove from Bhatey, Sundarban, India and Bangladesh [11,[23][24]. In the present study, all Eh value were less than 100 mV, indicating for anaerobic environment [21].…”

In order to clarify heavy metal concentration profiles in different mangrove forest ages, four sediment cores (up to 100 cm in depth) were collected and tested for their physicochemical characteristics (pH, Eh, organic matters and grain size) and heavy metal concentrations. Results showed that mangrove sediments were composed mainly of sandy silt, silty sand, silt, sandy mud and mud. The average mud content in the sediment cores continuously increased with mangrove forest ages from one, nine, nineteen and twenty years old, whereas the mud content highly fluctuated with the core depth. pH, Eh and organic matter content implied that the sedimentary depositional environments were classified as weak alkaline and anaerobic. The Cu and Zn concentrations in the sediment cores from the intertidal zone exceeded the TEL values in Canadian Interim Marine Sediment Quality Guideline (ISQGs) values, while, Pb concentration exceeded the PEL level. When compared with National Technical Regulation on Sediment Quality QCVN43:2012/BTNMT, sediment samples were polluted by Cu and Pb.

“…Low soil organic carbon concentration of the ponds sample may also be a factor causing low total abundance of pond soil bacteria. As reported Das (2012) who states that the c-organic is the most significant factors that regulate the concentration of total soil microbial population.…”

The impact of aquaculture activities has led to environmental degradation, especially ponds bottom soil quality. The purpose of this study was to assess the status of the ponds bottom ISSN 2157-6092 2016 www.macrothink.org/jee 2 soil quality in different aquaculture systems (traditional and intensive) in BLUPPB Karawang region in a flexible value of soil quality index (SQI). Twenty ponds consisting of 5 traditional of milkfish (Chanos chanos) juvenile rearing ponds and 5 traditional polyculture ponds, 5 intensive of Litopenaeus vannamei shrimp ponds lined with plastic mulch and 5 intensive L. vannamei shrimp earthen ponds. Variables of soil quality parameters examined include physical, chemical and biological of pond bottom soil. Sediment ponds with a depth of 5-10 cm were taken for analysis. Data statistically analyzed using Anova, continued with pos hoc test HSD Tukey. The results showed the ponds soil quality (SQI) of BLUPPB Karawang area has an average of 0.38 ± 0.02 or included in low criteria. Aquaculture systems were not significant (p> 5%) to the general status of ponds soil quality. Aquaculture systems (intensive and traditional) only gave a significant different (p<5%) to the parameter of soil bulk density, c-organic, total N, C:N ratio, total S, total P and soil respiration. Stability of the ponds bottom soil chemical compositions over time make level of intensity does not significantly affect, beside routine sediment removal at the end of cycle in intensive culture.

“…For example, in Sibuti wildlife sanctuary situated in the state of Sarawak, Malaysia, the pH of mangrove forest soil was acidic (3.34) [59,60], whilst the pH of mangrove soil in Pahang, Malaysia, was 6.1-6.4 at the time of measurement [33]. In Sundarbans mangrove forest, the soil was determined to be alkaline (7.2-8.4) [61]. In the present study, it was shown that strain MUSC 14 preferred to grow at pH 6-7 which shows that it adapted to the pH of mangrove forest in Pahang, Malaysia [33].…”

The mangrove ecosystem of Malaysia remains yet to be fully explored for potential microbes that produce biologically active metabolites. In the present study, a mangrove-derived Streptomyces sp. strain MUSC 14 previously isolated from the state of Pahang, Malaysia Peninsula, was studied for its potential in producing antioxidant metabolites. The identity of Streptomyces sp. strain MUSC14 was consistent with the genotypic and phenotypic characteristics of the Streptomyces genus. The antioxidant potential of Streptomyces sp. strain MUSC 14 was determined through screening of its methanolic extract against sets of antioxidant assays. The results were indicative of Streptomyces sp. strain MUSC 14 displaying strong antioxidant activity against ABTS, DPPH free radicals and metal chelating activity of 62.71 ± 3.30%, 24.71 ± 2.22%, and 55.82 ± 2.35%, respectively. The result of ferric reducing activity measured in terms of dose was equivalent to 2.35–2.45 μg of positive control ascorbic acid. Furthermore, there was a high correlation between the total phenolic content and the antioxidant activities with r = 0.979, r = 0.858, and r = 0.983 representing ABTS, DPPH, and metal chelation, respectively. Overall, the present study suggests that Streptomyces sp. strain MUSC 14 from mangrove forest soil has potential to produce antioxidant metabolites that can be further exploited for therapeutic application.
