Research ArticleOpen accessCrude Extract of Blue-Green Pigment Derived from the Marine Bacterium Pseudomonas aeruginosa P1.S9 has Antibacterial, Antioxidant, and Cytotoxic ActivitiesAris Tri Wahyudi, Rahmah Nursari, Widya Esti Purwaningtyas et al.Pigment derived from marine bacteria is one of the alternative sources of natural products characterized by beneficial functions for pharmaceutical purposes. This study aimed to evaluate the antimicrobial, antioxidant and cytotoxic activities of the marine bacterium Pseudomonas aeruginosa P1. S9 crude pigment extract and identify its chemical content. Crude pigment extract of this bacterium showed promising antibacterial activities against Pseudomonas … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 4 Mar 2022 · 6,994 accessesView PDF Cite

Research ArticleOpen accessPlant Growth Promoting Activity of Actinomycetes Isolated from Soybean RhizosphereAris Tri Wahyudi, Jepri Agung Priyanto, Resti Afrista et al.Plant Growth Promoting Rhizobacteria (PGPR) is considered as the biological agent for improving plant growth. One Group of PGPR that have an important role in growth promoting of plant is Actinomycetes. The objective of this study was to isolate and screen Actinomycetes isolated from soybean rhizosphere as growth promoter of soybean in vitro. Fifty-three Actinomycetes isolates have successfully been isolated … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 5 Jan 2019 · 14,604 accessesView PDF Cite

Research ArticleOpen accessScreening and Characterization of Sponge-Associated Bacteria Producing Bioactive Compounds Anti-Vibrio sp.Aris Tri Wahyudi, Jepri Agung Priyanto, Wenang Maharsiwi, Rika Indri AstutiIn Indonesia, vibriosis is the main disease in shrimp. This disease is caused by Vibrio sp that may decrease the productivity of shrimp cultivation. Thus, exploration for new bioactive compounds as vibriosis biocontrol agent is necessary. Marine sponge-associated bacteria is one of many sources for bioactive compounds. The aim of this study was to screen marine sponge-associated bacteria producing anti-Vibrio … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 5 Oct 2018 · 10,357 accessesView PDF Cite

Research ArticleOpen accessBioactive Compounds from Sponge Associated Bacteria: Anticancer Activity and NRPS-PKS Gene Expression in Different Carbon SourcesJepri Agung Priyanto, Rika Indri Astuti, Jun Nomura, Aris Tri WahyudiSponge associated bacteria with diverse NRPS-PKS genes could be the alternative source of bioactive compounds. This study aimed to analyze the activity as well as the regulatory mechanism regarding the anticancer properties derived from these bacteria against cancer cell lines. Extraction of bacterial metabolites using ethyl acetate solvent resulted yield ranging from 0.003 to 0.016% (w/v). Six extracts of bacterial … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 5 Oct 2017 · 8,886 accessesView PDF Cite
