“…Biofilms are almost composed of EPS, extracellular enzymes, and extracellular DNA, enabling bacteria to adhere to living or nonliving surfaces. − Therefore, the effect of compound C 1 on biofilm formation was spontaneously proposed and analyzed by crystal violet quantification assays. As depicted in Figure C , compared with control samples, compound C 1 at a dosage of 2.2 μg mL –1 was found to reduce 51.3% biofilm formation of Xoo cells.…”

Bacterial biofilms are the root cause of persistent and chronic phytopathogenic bacterial infections. Therefore, developing novel agrochemicals that target the biofilm of phytopathogenic bacteria has been regarded as an innovative tactic to suppress their invasive infection or decrease bacterial drug resistance. In this study, a series of natural pterostilbene (PTE) derivatives were designed, and their antibacterial potency and antibiofilm ability were assessed. Notably, compound C 1 displayed excellent antibacterial potency in vitro, affording an EC 50 value of 0.88 μg mL −1 against Xoo (Xanthomonas oryzae pv. oryzae). C 1 could significantly reduce biofilm formation and extracellular polysaccharides (EPS). Furthermore, C 1 also possessed remarkable inhibitory activity against bacterial extracellular enzymes, pathogenicity, and other virulence factors. Subsequently, pathogenicity experiments were further conducted to verify the above primary outcomes. More importantly, C 1 with pesticide additives displayed excellent control efficiency. Given these promising profiles, these pterostilbene derivatives can serve as novel antibiofilm agents to suppress plant pathogenic bacteria.

“…Li et al designed a kind of micelle, and the D-Tyrosine loaded on the micelle was released in an acidic environment to decompose the biofilm matrix [248]. Most studies have demonstrated the great clinical value of D-type amino acid, a dispersal factor of bacteria (Figure 13a) [249,250]. Furthermore, Olivier et al first studied the effect of human hormone atrial natriuretic peptide (hANP) on formation and dispersion of P. aeruginosa biofilm [251].…”

Preface to "Recent Advances in Antimicrobial Nanodrugs"Microbial infections have always posed a threat to public health, and the situation is becoming worse as some strains of these microorganisms develop resistance to drugs such as conventional antibiotics. With the rapid development of nanotechnology and nanomaterials, an increasing number of nanodrugs capable of fighting against various microorganisms (e.g., bacteria, fungi, and viruses) have been designed and prepared. The diversified size, shape, and chemical characteristics enable nanomaterials to facilitate molecular interactions with the microorganisms, and the high surface-to-volume ratio allows the incorporation of abundant functional moieties to these nanomaterials, thus promoting multivalent interactions with the microorganism. To date, the most commonly used antimicrobial nanomaterials include conventional metal (Ag, Cu, Zn, and Ti)-containing nanoagents, two-dimensional nanoagents (e.g., graphene materials, layered double hydroxides, transition-metal dichalcogenides, graphitic carbon nitride, MXenes, black phosphorus, and their derivatives), polymeric nanomaterials, nanomicelles and nanovesicles, carbon dots and silicon nanoparticles, aggregation-induced emission (AIE) nanodots, nanocomposite materials, etc. In addition, the nanomaterials with specific light-, heat-, electricity-, magnetic field-, and ultrasound-responsive properties, as well as excellent antimicrobial activity, have also attracted interest from a growing number of researchers. Common examples include nanoagents with a photodynamic therapy capacity and sonodynamic therapy activity. Further, nanozymes with antimicrobial activity have also drawn tremendous research interest from many researchers worldwide. In addition, chemodynamic therapy that utilizes Fenton or Fenton-like reactions to kill microbial cells represents an emerging research direction. Finally, the nanomaterials decorated with conventional antibiotics have also shown potential for achieving an enhanced antimicrobial capacity compared with free antibiotics.

“…Microbial growth inhibition usually takes a few minutes and the cell death might take several hours (Morley et al 2005;Kucera 2019;Silva et al 2020). The slow kinetics of inactivation can be overcome by increasing the biocide concentration or adding surfactants (Kucera 2019;Liu et al 2020). Notably, MIT presents high antimicrobial efficacy against a wide range of microorganisms, such as bacteria, algae, and fungi (Williams 2006;Majamaa et al 2011;Kucera 2015).…”

“…In the RO industry, MIT is frequently applied for both membrane storage and cleaning. This indicates that this chemical cannot only inhibit microbial growth but also it can remove mature biofilms by disrupting the EPS matrix of the biofilm (Kucera 2015;Kucera 2019;Liu et al 2020). Therefore, MIT is capable of preventing and controlling the biofouling of polyamide membranes.…”

Biofouling of polyamide membranes is one of the main barriers faced by reverse osmosis (RO) technologies to supply fresh water. Currently, biofouling is addressed by feed water pretreatment using chlorine, followed by membrane cleaning. Chlorine damages polyamide membranes and also generates harmful disinfection byproducts. Thus, safer strategies are needed to prevent biofouling in polyamide membrane systems. This review investigates the applicability of the following non-oxidizing biocides in preventing and controlling biofouling in RO systems, including their antimicrobial efficiency, hazard levels, membrane compatibility, and applicability to drinking water treatment: (1) 2,2-dibromo-3-nitropropionamide (DBNPA); (2) 2-methyl-4-isothiazolin-3-one (MIT); (3) sodium bisulfite (SBS), (4) phenoxyethanol (PE), (5) sodium benzoate (SB). According to this review, MIT and DBNPA present most of the features attributed to an ideal anti-biofouling chemical but also are the most hazardous biocides. Due to safety and efficacy, none of the five chemicals were determined to be the final solution to address membrane biofouling. However, alternative RO biocide research is in early development and requires further investigation via biofouling prevention studies. Therefore, future research efforts on the investigation of economic, eco-friendly, and safe antifouling agents to prevent and treat biofouling in RO systems are paramount to promote sustainable water supply in water-stressed countries.
