“…Quantification of the geochemical partitioning of heavy metals in sediments is necessary to understand the nature of the metals in sediments. The nature and bonds of metals in sediment were analyzed using a geochemical partitioning method of the sequential extraction process (SEP), proposed by the European Community Bureau of Reference (BCR), or the BCR-SEP procedures used in many studies [22][23][24][25][26]. The geochemical partition method has been applied in many studies to provide information such as i) characteristics of pollution sources, ii) evaluation of bioavailability and metal mobilization, and iii) identification of metal binding to assess metal accumulation, pollution, and transport mechanisms [27,28,29].…”

Activities such as fishing ports and power plants on the coast of Pelabuhanratu Bay have recently developed and hence, their input of metal-containing waste may influence the seawater quality of the bay as the fishing grounds. This study aimed to determine the potential sources (i.e., anthropogenic and natural) and pollution status in sediments. Sediment samples were collected once at 10 stations in the bay using a Van Veen grab. The geochemical partitioning of non-residual and residual phases of metals was used to assess the anthropogenic and natural sources, respectively. The status of metal contamination was evaluated by determining the geo-accumulation index (Igeo), contamination factor (CF), and pollution load index (PLI). Generally, Cu was dominant in residual fractions ranging 62.79-81.24%, while Zn ranged 39.56-66.02%. This suggests that Cu and Zn in Pelabuhanratu Bay are naturally sourced. Furthermore, the average geo-accumulation index of Cu was categorized as unpolluted (-0.86), and Zn was lightly polluted (0.87). The CF of Cu indicates the uncontaminated category (0.85), whereas Zn indicates a moderate contamination category (CF = 1.54). The pollution level (PLI) in Pelabuhanratu Bay is generally lightly polluted (PLI 1,135).

The present study demonstrated Corynebacterium amycolatum as an emerging MDR nosocomial pathogen with emphasis on recognition of the class A β-lactamase encoding gene. Analysis of phenotypic and genotypic features of virulence mechanisms including C. elegans survival response to infection to C. amycolatum (imipenem - resistant and susceptible) strains were also investigated. Antimicrobial resistance genes were detected by polymerase chain reaction. We also evaluated the ability of Corynebacterium amycolatum in its ability to colonize and kill or host in a C. elegans infection model system and we investigated the adherence and invasion persistence of C. amycolatum within HEp-2 and U-937 cells. This study identified two C. amycolatum strains penicillin resistant and were positive for the blagene, encoding a class A betalactamase. The ability to C. amycolatum to kill the nematode C. elegans was verified. All strains of C. amycolatum caused a decline in the survival curve of C. elegans. The interaction of nematode and C. amycolatum results in morphological changes: Dar formation and “bag of worms” in all tested strains. About U-937 macrophages assay, the data indicate that the samples of Corynebacterium amycolatum studied had greater ability to adhere to the surface in the first 3 hours of infection of the monolayers (p <0.05). According to current knowledge, this is the first identification of C. amycolatumbla gene positive. So, we suggest that medical surveillance programs should include control strategies in order to decrease potential risk factors of nosocomial infections due to C. amycolatum.
