“…Symbion microorganisms have the potential to produce secondary metabolites to protect host organisms, as a defense against pathogenic microorganisms, and for the purposes of interspecies communication [26]. Some luminescent microorganisms are reported to have antimicrobial properties, although so far luminescent microorganisms have not been explored as new potential for sources of antimicrobial agents for sources of antimicrobial agents for emerging global threats of multi drug resistant microorganisms [27]. showing antimicrobial activity against one pathogenic bacterium with inhibition zones ranging from 7 to 25 mm.…”

Bioluminescence means the ability of animals or plants to naturally produce light. The three known ways by which bioluminescence is produced are through specific cells called photocytes, bioluminescent glands in tissues and symbiotic bioluminescent microorganisms. Bioluminescence in Loligo duvaucelii is known to be caused by the presence of symbiotic microorganisms in bioluminescent sacs. There is a need to compile more information on bioluminescent symbiotic microorganisms on marine life in Indonesia and their potential. This study aims to determine the species of bioluminescent microorganisms on squid and fish, namely Loligo sp. and Loligo edulis from the waters of Jepara and the Bombay duck (Harpadon nehereus) from the Strait of Malacca, Indonesia and their potential. The samples were collected by isolating the microorganisms from the luminescent organs, after which the bioluminescent microorganisms were used in the research. This research consisted of antimicrobial tests against pathogenic microorganisms which were conducted qualitatively. The bioluminescent microorganisms were identified using biochemical assay and molecular assay (16S rRNA PCR). Tests results from Loligo sp. symbiotic microorganisms found two isolates which showed antimicrobial activities against pathogenic Multi Drug Resistant (MDR) microorganisms, namely uncultured bacterium clone 1P-1-G05 against Escherichia coli with 32.59 mm of inhibitory zone and Uncultured bacterium clone 3g10a against Enterobacter sp. with 28.44 mm of inhibitory zone. The bioluminescent symbiont microorganisms in Loligo edulis, which was identified to be Photobacterium phosphoreum, showed antimicrobial activities against Vibrio harveyi, E. coli, Staphylococcus aureus, and Bacillus sp. Bioluminescent symbiotic microorganisms on H. nehereus identified Alteromonas macleodii, which showed gamma hemolysis on the blood agar test.

“…In recent years, there has been a growing interest in research and development of new antimicrobial agents to combat microbial resistance. All of the most important groups of antibiotics (tetracyclines, cephalosporins, aminoglycosides and macrolides) were discovered in the 1960s and these compounds are in danger of losing their efficacy because of the increase in microbial resistance [ 20 ], due especially to the emergence of multidrug-resistant bacteria [ 21 , 22 , 23 ]. For this reason, the discovery of new antibiotics is one of the main objectives of medicine nowadays [ 24 ].…”

The increase of many deadly diseases like infections by multidrug-resistant bacteria implies re-inventing the wheel on drug discovery. A better comprehension of the metabolisms and regulation of diseases, the increase in knowledge based on the study of disease-born microorganisms’ genomes, the development of more representative disease models and improvement of techniques, technologies, and computation applied to biology are advances that will foster drug discovery in upcoming years. In this paper, several aspects of current methodologies for drug discovery of antibacterial and antifungals, anti-tropical diseases, antibiofilm and antiquorum sensing, anticancer and neuroprotectors are considered. For drug discovery, two different complementary approaches can be applied: classical pharmacology, also known as phenotypic drug discovery, which is the historical basis of drug discovery, and reverse pharmacology, also designated target-based drug discovery. Screening methods based on phenotypic drug discovery have been used to discover new natural products mainly from terrestrial origin. Examples of the discovery of marine natural products are provided. A section on future trends provides a comprehensive overview on recent advances that will foster the pharmaceutical industry.

“…Antibiotic usage has contributed to the emergence of antibiotic resistance, diminishing the bactericidal efficacy of antibiotics at previously effective doses. This phenomenon poses a significant threat to human life and health, as multidrug-resistant bacteria (MDR) have re-emerged, causing severe and incurable diseases [1]. In response to this challenge, researchers have turned to inorganic nanoparticles (NPs), such as silver nanoparticles (AgNPs), copper nanoparticles (CuNPs), and zinc nanoparticles (ZnONPs), as potential antibacterial agents.…”

Gold nanoparticles (AuNPs) have garnered attention as a potential alternative to conventional antibiotics due to their innovative antibacterial properties. This study demonstrates the successful production of biosynthetic gold nanoparticles (bAuNPs) using Pseudomonas aeruginosa (P. aeruginosa) as spherical nanostructures at 58 °C for 24 h, under alkaline pH (9.0). The successful synthesis of bAuNPs was confirmed through UV-Vis spectroscopy, exhibiting a characteristic peak within the 500–600 nm wavelength range, and the evaluation of the main functional groups and morphology were stressed by Fourier Transform Infrared Spectroscopy (FT-IR) and Transmission Electron Microscopy (TEM), respectively. Subsequently, the synthesized bAuNPs were combined with low concentrations of ampicillin and evaluated against Methicillin-Susceptible Staphylococcus aureus (MSSA) and Methicillin-Resistant Staphylococcus aureus (MRSA) through the classical serial dilution method. This innovative approach holds the potential to address the escalating issue of antibiotic resistance, providing a viable and sustainable solution.
