Biosynthesis of silver nanoparticles from Aeromonas sobria and antibacterial activity against fish pathogens

Evaluation of the antibacterial influence of silver nanoparticles against fish pathogenic bacterial isolates and their toxicity against common carp fish

“…Previously, the plant‐mediated AgNPs were used against several fish infection‐causing bacterial isolates. The best antibacterial activity was observed against A. hydrophila (Erdem, Dayangaç, Kıray, & Duygu, 2019; Mahanty et al, 2013). However, many previous findings revealed that the AgNPs are much toxic to the environment, especially the aquatic ecosystem, for instance, the toxicity of AgNPs against three different invertebrates (Lekamge et al, 2018) and assessment of AgNPs toxicity in Prochilodus lineatus fish by Ale et al (2018).…”

Mechanisms and applications of microbial synthesis of metal nanoparticles in agri-sectors

“…216 AgNPs synthesized by Pseudomonas sp. and coated on TEMPO-oxidized bacterial cellulose (BBC) membranes, 217 silver oxide (Ag 2 O) nanoparticles by Bacillus paramycoides , 218 and AgNPs by Aeromonas sobria , 219 the cyanobacteria Synechococcus elongatus , and the algae Phormidium fragile , 220 along with zinc oxide nanoparticles (ZnONPs) by lactic acid bacteria, 221 have all demonstrated significant bactericidal activity against several aquatic and fish pathogens, including Serratia marcescens , Aeromonas hydrophila , and Vibrio harveyi . Furthermore, the combined use of MNPs and microbial enzymes has been proven to facilitate the degradation of antibiotics.…”

Applications of Nanotechnology in Fish Health

“…Most recently Erdem and co-researchers prepared AgNPs from Aeromonas sobria to check their antibacterial properties against various fish pathogens (E. hermannii, P. rettgeri, H. alvei, M. morganii subsp.Sibonii, C. braakii, A. hydrophila, E. coli and E. cloacae). And for the management of fish health, NPs were approved as antimicrobial agents against A. hydrophila(Erdem et al 2018). Nanoencapsulation technique reveals new assets like the adding of carbon nanotubes into trout fish diet causing in the preparation of hard pelleted feed.…”
