The aim of this study was to evaluate the antibacterial activity of ethanol concoction (mixed extract) of three herbs plants, such as: Boesenbergia pandurata, Solanum ferox and Zingimber zerumbet against Aeromonas hydrophila, Pseudomonas sp. and both bacteria. The Plant extracts were obtained by using ethanol and the concentration of the extract was 600 mgL-1 of B. pandurata, 900 mgL-1 of S. ferox and 200 mgL-1 of Z. zerumbet. The inhibition zone was measured after 6, 12, 18, 24 h incubation at 30o C. The ratios of concoction S. ferox and B. pandurata (for 100 mL solution) were 90:10; 80:20; 70:30; 60:40; 50:50; 40:60; 30:70; 20:80; 10:90. The same ratios were made on the concoction of S. ferox and Z. zerumbet. The concoctions of S. ferox and B. pandurata in the ratio of 50:50 and 60:40, and the concoction of S. ferox and Z. Zerumbet with ratio 60:40 had higher antibacterial activity against A. hydrophila single isolate compared to the other concoctions. Furthermore, the concoction extract of S. ferox and B. pandurate 50:50 and the combined of S. ferox and Z. zerumbet ratio 50:50 and 90:10 were the best combination to inhibit the growth of a single bacterium Pseudomonas sp. The combined S. ferox and B. pandurata ratio 50:50; 10:90 and S. ferox mixed with Z. zerumbet ratio 50:50 and 40:60 were the best combination against the combined bacteria between A. hydrophila and Pseudomonas sp. The conclusion of this research was the combined extract of S. ferox and B. pandurata and S. ferox with Z. zerumbet are effective to suppress the growth of single or combination of A. hydropila and Pseudomonas sp.

A pathogenicAeromonas hydrophilastrain An4 was isolated from marine catfish and characterized with reference to its proteolytic and hemolytic activity along with SDS-PAGE profile (sodium dodecyl sulphate-Polyacrylamide gel electrophoresis) of ECPs (extracellular proteins) showing hemolysin (approximately 50 kDa). Agar well diffusion assay using crude cell extract of the bacterial isolate clearly demonstrated antibacterial activity against indicator pathogenic bacteria,Staphylococcus arlettaestrain An1,Acinetobactersp. strain An2,Vibrio parahaemolyticusstrain An3, andAlteromonas aurentiaSE3 showing inhibitory zone >10 mm well comparable to common antibiotics. Further GC-MS analysis of crude cell extract revealed several metabolites, namely, phenolics, pyrrolo-pyrazines, pyrrolo-pyridine, and butylated hydroxytoluene (well-known antimicrobials). Characterization of EPS using FTIR indicated presence of several protein-related amine and amide groups along with peaks corresponding to carboxylic and phenyl rings which may be attributed to its virulent and antibacterial properties, respectively. Besides hemolysin, EPS, and protease,Aeromonas hydrophilastrain An4 also produced several antibacterial metabolites.

Indonesia has many local plants with potential as herbal antibacterial properties, one of which is the local black fruit of Wandama. The objective of this study is to determine the antibacterial activity of the extract of black fruit seed against A. Hydrophila by in vitro and FTIR by Tilapia. The benefit of this research is to make black fruit seed extract as a natural remedy against tilapia attacked by Aeromonas Hydrophila. The antibacterial activity of black fruit seed extract against A. Hydrophila is investigated in vitro and using FTIR on tilapia in this research. The aim of this study is to establish black fruit seed extract as a natural treatment for tilapia infected with Aeromonas Hydrophila. The disc approach was used to conduct the in vitro research. Agar medium was poured into a sterile petri dish, and 2 drops of bacteria from the liquid medium were uniformly distributed and cooled. On the press, disc paper with black fruit seed extract was put and incubated for 18-24 hours at 35 C. An FTS 1000 version spectrophotometer system was used for the FTIR test. For the FT-IR study, a fraction of dried black fruit seeds was used. For clear preparation, 100 mg of dry extract is condensed in KBr pellets. A specimen of loaded black fruit seed samples was analyzed using FT-IR spectroscopy with a scanning range of 400-4000 cm-1 and a resolution of 4 cm-1. The results showed that the ethyl acetate fraction produced an inhibition zone (13.65 mm), the water fraction produced an inhibition zone (11.21 mm), and the n-hexane fraction produced the weakest inhibition zone (11.21 mm) (5.31mm). The concentration test results from 125 ppm, 250 ppm, 500 ppm and 1000 ppm obtained a large inhibition zone at a concentration of 1000 ppm with an inhibition zone area of 11.43 + 0.02. The absorbance value of black fruit seed extract in ethyl acetate solvent at 3430 cm-1 revealed the absorption band with the strongest vibration of the hydroxylate (-OH) functional group, according to FTIR research. Final thoughts with an average value of 13.65 + 0.06, black fruit seed extract using ethyl acetate can inhibit A. Hydrophila bacteria.

Soil bacteria play an interesting role in the reduction of Ag+ ions and the formation of silver nanoparticles (AgNPs), which may be a good source for nanoparticles and play a major role in nanotechnology applications. The concept of this project was to study the effects of these environmentally produced nanoparticles on the growth of some pathogenic bacteria. The environmental bacteria were isolated from soil, purified on broth cultures, and centrifuged, while the supernatant was extracted to detect its ability to convert silver nitrate to nanoparticles. The AgNPs was detected by Atomic Force Microscopy (AFM), while Granularity Cumulating Distribution (GCD) was employed to estimate the AgNPs sizes. The results showed the synthesis of AgNPs with sizes of 63.50nm and 45.81nm from the extracts of environmental Pseudomonas sp. and Enterobacter, respectively. The synthesized AgNPs from the extracts of all environmental bacteria showed antibacterial activity against some pathogenic bacteria (Gram positive and Negative) with variable inhibition zones. In conclusion, environmental bacteria can be a cheap source of nanoparticles.
