“…Mangroves have many marine organisms (Ariyanto et al, 2020) and have good nutrition sources (Ariyanto, 2019) and amino acid contents (Ningsih et al, 2020). This is supported by the physicochemical factors and litter dynamics of mangroves (Ariyanto et al, 2019) and the decomposition of leaves over time (Ariyanto et al, 2018).…”

Actinomycetes are a group of bacteria that are widely distributed in soil, litter, water, and other natural sources. These Gram positive bacteria can produce hundreds of bioactive compounds, especially antibiotics. This research isolated culturable actinomycetes from mangrove sediments in the Semarang and Karimunjawa Island areas. The isolates that produce potential antibacterial compounds were identified by qualitative screening using the Biosynthetic Gene Cluster (NRPS/PKS) prediction approach. This research was conducted from June to November 2020. A total of 19 actinomycetes from Semarang and 17 actinomycetes from Karimunjawa were found to have at least one type of Biosynthetic Gene Cluster (NRPS, Type I or Type II PKS), but only three isolates had antibacterial activity against S. aureus, E. coli, and L. monocytogenes. Molecular identification found that the bacteria were similar to Brachybacterium paraconglomeratum (99.92%), Streptomyces pluripotens (100%), and Micromonospora chersina (99.08%). Results of the study concluded that the three bacterial isolates that had bacterial activity have similar genes with known antibiotic-producing genes and can potentially provide new antibiotic candidates.

“…There are many marine ecosystem specifications in Indonesia, namely coral reefs, seagrass (Unsworth et al, 2018), seaweed (Pringgenies et al, 2020) and mangrove ecosystems (Ariyanto et al, 2020). Each of these ecosystems has a high level of biodiversity because all three have different environmental characteristics (Ariyanto et al, 2019a), secondary metabolite (Ariyanto et al, 2019b;Ningsih et al, 2020) and marine organisms (Ariyanto et al, 2018;Santosa et al, 2020).…”

Sponges are marine organisms that have associations with microorganisms. The association fungi in sponges have a chemical and ecological relationship. These bioactive compounds have potential in the pharmaceutical field. This research aimed to explore bioactive compounds of association fungi in sponges that live in coral, seaweed and mangrove ecosystems. The research consisted of isolation, purification, extraction, antibacterial testing, molecular identification, antioxidant testing and toxicity testing. The research was conducted on March to September 2020 in Karimunjawa Island. The results showed that the sponge association fungi isolates had antibacterial activity against the Multi Drug Resistant (MDR) pathogens Staphylococcus aureus (Sa), Escherichia coli (Ec), and Staphylococcus epidermidis (Se), Pseudomonas aeruginosa (Pa) and the fungi Candida albicans (Ca). The identification results of the active association fungi were Circinelloides sp., Xylariaceae sp., Trichoderma asperellum, Aspergillus sp. and Pleosporales sp. . The extracts of these fungi had antioxidant activity with an IC50 value of 1071,62; 643,35; 1020,32; 805,70 and 784,31 mg/L. Furthermore, they also had an LC50 value of 462,67; 355,47; 504,92; 482,15 and 435,88 mg/L. Keywords: Antimicrobial, Antioxidant, Fungi, Sponge, Symbiosis

“…After this incident, Indonesian people together with theGovernment planted mangroves to improve the man-grove ecosystem on the Indonesian coast. Moreover, mangrove can be used as a source nutrition and habitat for marine organism (Ariyanto et al, 2020;Ningsih et al, 2020). The high level of nutrients in the mangrove area was caused by the mangrove waste, which turned into mangrove litter and was decomposed by bacteria, making it useful as a nutrient.…”

Highlight ResearchAntimicrobial potential against the test microbesRhizhopora mucronata isolate showed 95% homology with Bacillus subtilis, and 97% homology with Bacillus oceanisediminis,Acanthus ilicifolius isolate showed 96% homology with Paracoccus caeni, and 89% homology with Bacillus circulans. The study found 4 isolates with antimicrobial potency against MDR pathogenic microbes.The symbiont microbes taken from Rhizophora mucronata and Acanthus ilicifolius were determined to be of the genus Bacillus and Paracoccus AbstractAntimicrobial property of mangrove symbiont have the ability to fight Multi Drug Resistant bacteria which were Staphylococcus aureus, Escherichia coli, and Vibrio haryeyi. This study aimed to determine the potential of symbiont microbes from the root of Rhizopora mucronata and Acanthus iilicifolius as antimicrobial agents against multi-drug resistant (MDR) pathogenic microbes. This research was conducted during July to November 2020. The MDR bacteria were S. aureus, E. coli, and V. harveyi MDR test microbes. The symbiont microbes were identified through molecular analyses (PCR 16S rDNA). Isolation of symbiont microbes from R. mucronata resulted in 16 isolates, while isolation from A. iilicifolius resulted in 14 isolates. Based on the antimicrobial qualitative test against S. aureus, 8 out of 16 microbial isolates from R. mucronata were found to show antimicrobial properties. The testing of A. ilicifolius symbiont microbes against S. aureus showed 8 out of 14 isolates with antimicrobial properties. The test against E. coli resulted in 2 out of 16 microbial isolates from R. mucronata and 5 out of 14 isolates from A. ilicifolius with antimicrobial properties. The test against V. harveyi resulted in two out of 16 microbial isolates from R.mucronata and 4 out of 14 isolates from A. ilicifolius with antimicrobial properties. The quantitative test found 2 isolates from R. mucronta, namely isolates RM10 and RM12, with antimicrobial properties against MDR strain E. coli, with the best isolate being RM10, which produced 11.22 mm of inhibition zone diameter. Furthermore, the selection of isolates was based on the size of the inhibition zone, the clearness of the inhibition zone and the potential for antibacterial activity. Based on their overall antimicrobial potential against the test microbes, four isolates were selected. Molecular analyses of RM12 isolate showed 95% homology with Bacillus subtilis, of RM 10 isolate showed 97% homology with Bacillus oceanisediminis, of AC isolate showed 96% homology with Paracoccus caeni, and of AC 5 isolate showed 89% homology with Bacillus circulans. The study found four isolates with antimicrobial potency against MDR pathogenic microbes. The symbiont microbes taken from R. mucronata and A. ilicifolius were determined to be of the genus Bacillus and Paracoccus.
