“…29 Kirzhner et al investigated 20 kHz-ultrasound efficiency to remove microbial biofilm in waste water with heterotrophic aerobic bacteria and demonstrated that ultrasound treatment is effective in removing biofilm by more than two orders of magnitude. 25 Phull et al showed that ultrasound is suitable for water desinfection, whereas ultrasound at high frequencies seemed to be more effective with regards to bactericidal effects. 30 Nishikawa et al demonstrated that Staphylococcus mutans biofilm can be effectively removed by ultrasonic exposure 31 in an in vivo model, and Xu et al demonstrated that high-intensity focused ultrasound is able to destroy Pseudomonas aeruginosa biofilm.…”

“…[17][18][19] The ability of ultrasonic cavitation to destroy biofilm extracellular matrix in a mechanical fashion, and remove bacterial cells from the surface has been studied and described in many studies. [20][21][22][23][24][25] Intensity and treatment time is currently the subject of debate. Moreover, there is scant literature on the specific use of this treatment modality in the context of arthroplasty-related infections.…”

Low‐frequency sonication may alter surface topography of endoprosthetic components and damage articular cartilage without eradicating biofilms completely

Two-stage exchange arthroplasty is the current standard of care for arthroplasty-related infections. Reinfection rates up to 30% are reported, and there is significant morbidity for the patient. In cases of failure, arthrodesis or amputation may result. Ultrasonic treatment has the potential to eradicate biofilms and avoid two-stage exchange arthroplasty. Data in the specific context of arthroplasty infections is scant, and there is debate regarding optimal frequency and intensity of treatment. Surface topography alterations of the endoprosthetic components and damage to adjacent bone and cartilage have not been investigated. We found incomplete biofilm eradication and significant increase in surface roughness (maximum peak-to-valley height) of cobalt-chrome unicondylar knee components as well as reduction in articular cartilage thickness area from 10 retrieved femoral heads after low-frequency sonication treatment according to manufacturer-specified recommendations. Our data collectively suggest that sonication treatment for biofilm eradication in arthroplasty infections may not be effective and surface topography alterations may potentially reduce implant longevity.

“…Four root segments (approximately 2 cm in length and 0.3–0.5 cm in thickness) were obtained from each plant system. Subsequently, the root segments were washed by shaking three times in 10 ml of tap water, twice in 10 ml of distilled water, and once in 20 ml of sterile 0.85% NaCl ( Kirzhner et al, 2009 ; Li et al, 2013 ).…”

“…The samples were filtered through sterile mixed esters of cellulose membranes (S-Pak Membrane Filters, 47 mm diameter, 0.22 μm pore size, Millipore Corporation, Billerica, United States). The filters obtained were placed on 2% Nutrient (Difco-BD, Sparks, United States) and R2A (Lab M, Lancashire, United Kingdom) agar media and plates were incubated for 48 h at 25 and 37°C, respectively ( Calheiros et al, 2009 ; Kirzhner et al, 2009 ). An aliquot of the samples (50 μl) was also directly spread without filtering on the surface of each medium and incubated in the same conditions.…”

Unraveling the Composition of the Root-Associated Bacterial Microbiota of Phragmites australis and Typha latifolia

et al. 2018

Phragmites australis and Typha latifolia are two macrophytes commonly present in natural and artificial wetlands. Roots of these plants engage in interactions with a broad range of microorganisms, collectively referred to as the microbiota. The microbiota contributes to the natural process of phytodepuration, whereby pollutants are removed from contaminated water bodies through plants. The outermost layer of the root corpus, the rhizoplane, is a hot-spot for these interactions where microorganisms establish specialized aggregates designated biofilm. Earlier studies suggest that biofilm-forming members of the microbiota play a crucial role in the process of phytodepuration. However, the composition and recruitment cue of the Phragmites, and Typha microbiota remain poorly understood. We therefore decided to investigate the composition and functional capacities of the bacterial microbiota thriving at the P. australis and T. latifolia root–soil interface. By using 16S rRNA gene Illumina MiSeq sequencing approach we demonstrated that, despite a different composition of the initial basin inoculum, the microbiota associated with the rhizosphere and rhizoplane of P. australis and T. latifolia tends to converge toward a common taxonomic composition dominated by members of the phyla Actinobacteria, Firmicutes, Proteobacteria, and Planctomycetes. This indicates the existence of a selecting process acting at the root–soil interface of these aquatic plants reminiscent of the one observed for land plants. The magnitude of this selection process is maximum at the level of the rhizoplane, where we identified different bacteria enriched in and discriminating between rhizoplane and rhizosphere fractions in a species-dependent and -independent way. This led us to hypothesize that the structural diversification of the rhizoplane community underpins specific metabolic capabilities of the microbiota. We tested this hypothesis by complementing the sequencing survey with a biochemical approach and scanning electron microscopy demonstrating that rhizoplane-enriched bacteria have a bias for biofilm-forming members. Together, our data will be critical to facilitate the rational exploitation of plant–microbiota interactions for phytodepuration.

“…Cleaning ability of HPU has been widely demonstrated to remove sediment from food (Zhao et al, 2009), plants (Kirzhner, Zimmels, Malkovskaja, & Starosvetsky, 2009) and membrane filters (Muthukumaran et al, 2005). One significant problem with this technology is an ability to induce surface erosion of stainless steel (Haosheng, Jiadao, & Darong, 2009), cleaning tanks (Krefting, Mettin, & Lauterborn, 2004) and ultrasonic sonotrodes.…”
