“…Ksontini and co author, pointed that dairy biofilm formation depends on the types of surface material and bacterial community that investigated the biofilm formation based on thermodynamic approach (17). Antibiotic susceptibility profile by Vitek AST to K. pneumonia and E. coli (Table 1) revealed that both biofilm forming bacteria were resistant to most antibiotics used in this test which was confirmed by the previous studies (18,19). The MIC breakpoints according to M100 (20)…”

“…The biofilm-forming bacteria displayed antibiotics resistant patterns. Many studies approved that biofilm bacteria were multi-drug resistance bacteria (18,19,21,22). The reasons behind their resistance were antibiotics penetration difficulty(23), extracellular matrix act at shield and chelating agent (24) and low bacterial metabolic state (25).…”

Date palm silver nanoparticles are a green synthesis method used as antibacterial agents. Today, there is a considerable interest in it because it is safe, nontoxic, low costly and ecofriendly. Biofilm bacteria existing in marketed local milk is at highly risk on population health and may be life-threatening as most biofilm-forming bacteria are multidrug resistance. The goal of current study is to eradicate biofilm-forming bacteria by alternative treatment green synthesis silver nanoparticles. The biofilm formation by bacterial isolates was detected by Congo red method. The silver nanoparticles were prepared from date palm(khestawy) fruit extract. The formed nanoparticles were characterized with UV-Vis and AFM. The antibacterial activity of synthetic silver nanoparticles was evaluated by agar well diffusion method. Gram-negative bacteria isolates were E. coli in 3 isolates and Klebsiella pneumoniae in 5 isolates and all are biofilm producer. The size of synthetic green silver nanoparticles is 18 nm and the generation of silver nanoparticles was confirmed by change of date extract color from yellow to brown with an absorption maximum at 410 nm. Highly antibacterial activity of silver nanoparticles was recorded in comparison to plant extract and silver nitrate against gram-negative biofilm-forming bacteria. From this study, the antibacterial activity of date palm silver nanoparticles was more efficient to eradicate gram negative biofilm[1]forming bacteria isolated from marketed local milk

Silver nanoparticles have been considered a powerful antimicrobial agents recently especially after increasing incidence of diseases associated with biofilm and multi-drug resistant pathogens required to find a novel path to eradicate that challenge. The present study aims to evaluate the antibacterial activity of biosynthesized silver nanoparticles (AgNPs) using a cell-free extract of Enterobacter cloacae and chemo synthesis by sodium borohydride (NaBH 4 ) on biofilm-forming Pseudomonas oryzihabitans. Antimicrobial effect of silver nanoparticles in both types and in combination with imipenem were evaluated by agar well diffusion method. The results revealed a good response to inhibit biofilm-forming Pseudomonas oryzihabitans growth by silver nanoparticles antibacterial activity in both types (biological and chemical) and in combination with imipenem; the antimicrobial effect was increased and enhanced. In the present study, it was found that the biological and chemical silver nanoparticles were considered a novel and decisive solution against biofilm and multi-drug resistance bacteria with a preference of biological silver nanoparticles.

“…Pseudomonas oryzihabitans is a gram negative yellow pigmented, oxidase negative, rod shaped bacteria (Hasson, 2019). It is an opportunistic pathogen of humans and warm-blooded animals and known to cause septicemia, peritonitis, endophthalmitis, skin and soft tissue infections, and bacteremia (Freney et al, 1988;Panagopoulos et al, 2016;Tena & Fernández, 2015;Woo et al, 2014).…”

The banana is the most produced fruit in the world, it is estimated that in 2018, more than 115.7 million tons were produced worldwide (Food and Agriculture Organization of the United Nations [FAO], 2020), Brazil occupies a prominent position, producing approximately 6.75 million tons, in an estimated area of 449,284 hectares. It is the fourth largest fruit producer of the world, behind India, China and Indonesia (FAO, 2020).
