Abstract Oral diseases (e.g., dental caries, periodontitis) are developed when the healthy oral microbiome is imbalanced allowing increase of pathobiont strains. Common practice to prevent or treat such use antiseptics, like chlorhexidine. However, impact these antiseptics on composition and metabolic activity poorly addressed. Using two types biofilms—a 14-species community (more controllable) human tongue microbiota representative)—the short-term chlorhexidine exposure was explored...
A key step toward energy-positive sewage treatment is the development of mainstream partial nitritation/anammox, a nitrogen removal technology where aerobic ammonium-oxidizing bacteria (AerAOB) are desired, while nitrite-oxidizing (NOB) not. To suppress NOB, novel return-sludge was investigated. Single and combined effects sulfide (0-600 mg S L-1), anaerobic starvation (0-8 days), free ammonia (FA) shock (30 FA-N L-1 for 1 h) were tested immediate long-term recovery. AerAOB NOB inhibited...
Abstract Post-weaning diarrhoea (PWD) in piglets presents a widespread problem industrial pig production and is often caused by enterotoxigenic E. coli (ETEC) strains. Current solutions, such as antibiotics medicinal zinc oxide, are unsustainable increasingly being prohibited, resulting dire need for novel solutions. Thus, this study, we propose evaluate protein-based feed additive, comprising two bivalent heavy chain variable domain (V H H) constructs H-(GGGGS) 3 -V H, BL1.2 BL2.2) an...
The development of viability quantitative PCR (v-qPCR) has allowed for a more accurate assessment the microbial sample by limiting amplification DNA from dead cells. Although valuable, v-qPCR is not infallible. One most factors live/dead distinction length qPCR amplicon used. However, no consensus or guidelines exist selecting and designing lengths optimal results. In this study, wide range incrementally increasing (68 to 906 base pairs [bp]) was used on live killed cells nine bacterial...
Abstract Physicochemical water disinfection methods result in the reduction of bacterial concentrations by orders magnitude, but not total elimination community. As such, dead biomass may act as a carbon and nutrient source for survivor populations. The ability strains to grow on cells has been described before necrotrophy. We investigated impact killed two different growth potential natural drinking microbial communities. Many indigenous taxa could biomass, with concentration increasing...

Deep-sea environments can become contaminated with petroleum hydrocarbons. The effects of hydrostatic pressure (HP) in the deep sea on microbial oil degradation are poorly understood. Here, we performed long-term enrichments (100 days) from a natural cold seep while providing optimal conditions to sustain high hydrocarbon rates. Through at increased HP and ambient (AP) by using control marine broth, demonstrated that both carbon source have big impact community structure. In contrast...
Chlorhexidine mouthrinses are marketed in different formulations. This study aimed at investigating qualitative and quantitative changes in-vitro multispecies oral biofilms, induced by chlorhexidine-containing mouthrinses.Earlier studies comparing chlorhexidine either clinical or assessing the antimicrobial efficacy of mouthrinses. However, no clear investigations available regarding ecological impact formulations on biofilms after rinsing with formulations.Nine commercially were selected....
Abstract Determination of bacterial community composition in synthetic communities is critical for understanding microbial systems. The typically determined through plating or PCR-based methods which can be labor-intensive, expensive prone to bias. Simultaneously, flow cytometry has been suggested as a cheap and fast alternative. However, since the technique captures phenotypic state cells, accurate determination could affected when bacteria are co-cultured. We investigated performance...
ABSTRACT Antiseptics are widely used in oral healthcare to prevent or treat diseases, such as gingivitis and periodontitis. However, the incidence of bacteria being tolerant standard antiseptics has sharply increased over last few years. This stresses urgency for surveillance against organisms, well discovery novel antimicrobials. Traditionally, susceptibility antimicrobials is assessed by broth micro-dilution disk diffusion assays, both which time-consuming, labor-intensive, provide limited...
