Abstract

Potential of marine photosynthetic bacteria (MPB) and their biopigment extracts as antimicrobial agents against two major aquatic pathogens, Aeromonas hydrophila and Staphylococcus aureus. The research was conducted from February to April 2025. Six MPB isolates were cultured under laboratory conditions to induce pigment production. Biopigments, natural pigments produced by microorganisms, exhibit antimicrobial and antioxidant properties. Pigment extraction was performed using acetone and ether, followed by evaporation to obtain concentrated pigment extracts. The antimicrobial activity of both MPB suspensions and their biopigment extracts was tested using the disc diffusion method on Mueller-Hinton Agar (MHA) media. The results showed that the MPB suspensions produced no inhibition zones against either pathogen. In contrast, the biopigment extracts demonstrated weak antimicrobial activity, with inhibition zone diameters ranging from 1 to 4 mm, a classification of weak. However, the ability of biopigment extracts to inhibit bacterial growth, even at low levels, suggests the presence of bioactive compounds with potential antimicrobial activity. These findings suggest that MPB-derived biopigments may serve as a natural alternative in future antimicrobial development

Abstract

Carotenoids are natural pigments with significant potential that are widely synthesized by photosynthetic bacteria. In addition to playing a role in photosynthesis, carotenoids also function as natural antioxidants capable of inhibiting the formation of free radicals and providing protection against oxidative stress. This study aims to characterize and to identify carotenoid pigments synthesized by marine photosynthetic bacteria, to determine the types of pigments, as well as to prove their antioxidant activity. The method used in this study was experimental, conducted to test the ability of marine photosynthetic bacteria to synthesize carotenoid pigments as producers of antioxidant compounds. The results of the study indicate that isolate LD07, a photosynthetic marine bacterium, contains carotenoid pigments. UV-Vis spectrophotometer analysis revealed a maximum absorption peak at a wavelength of 490 nm, a value within the characteristic absorption region of carotenoid pigments

Abstract

Shrimp is one of the key fishery commodities for the national economy. The main problem in shrimp farming is infection by the bacterium Vibrio harveyi, which is commonly controlled using conventional antibiotics. Uncontrolled antibiotic use can lead to bacterial resistance; therefore, it is necessary to identify alternative antibacterial compounds that are more environmentally friendly, such as carotenoid pigment extracts from marine microorganisms. This study aims to analyze the antibacterial activity and determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of carotenoid pigment extracts against V. harveyi. Carotenoid pigment analysis was performed using UV-Vis spectrophotometry, while antibacterial activity was tested using the disk diffusion method (Kirby-Bauer). MIC and MBC were determined using the liquid dilution and pour plate methods. The extract concentrations used were 12,5%, 25%, 50%, and 100%. The results showed that the extract exhibited a maximum absorbance at 490 nm, with a total carotenoid content of 14.56 µg/mL. In addition, the carotenoid pigment extract from isolate LD02 inhibited the growth of V. harveyi, with inhibition zones ranging from 1.41 to 3.58 mm. The MIC was 14.56 µg/mL, while the MBC was>14.56 µg/mL, indicating that the extract exhibits bacteriostatic activity against V. harveyi.

Abstract

Marine photosynthetic bacteria are microorganisms with the potential to produce bioactive compounds in the form of carotenoid pigments, which can be utilized as a natural source of antibacterial agents. This study aims to characterize the carotenoid pigments produced by the marine photosynthetic bacterial isolate LD04 and to determine their potential antibacterial activity against the pathogenic bacteria Pseudomonas aeruginosa, Escherichia coli, and Vibrio harveyi. The study was conducted using an exploratory descriptive method, involving bacterial culture, antibacterial activity testing using the disc diffusion method, biomass production, pigment extraction using methanol, and purification and characterization using Thin Layer Chromatography (TLC) and High-Performance Liquid Chromatography (HPLC). LC analysis yielded a single major spot, indicating the presence of a dominant pigment component in the extract. Further characterization by HPLC at a wavelength of 450 nm produced a peak at a retention time of 6.35 minutes, whereas the astaxanthin standard was detected at 28.2 minutes. This difference in retention time suggests that the main compound in the extract is likely a xanthophyll or a more polar carotenoid derivative. Antibacterial activity testing showed that the pigment extract was able to inhibit the growth of E. coli and V. harveyi, but showed no activity against P. aeruginosa. The largest inhibition zone diameters were obtained for E. coli at 5.63 mm and V. harveyi at 1.23 mm, classified as weak inhibition according to CLSI standards. Based on the research results, it can be concluded that the carotenoid pigments from the marine photosynthetic bacterial isolate LD04 have potential as a source of natural antibacterial agents, particularly against E. coli and V. harveyi.
