Philos. 3A) and genus (Fig. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Sodium Citrate, Dihydrate . Biofilms were collected for confocal laser scanning microscopy (CLSM) observation and quantification, as well as genomic DNA extraction, at four time points: days 7, 14, 21, and 28, to investigate the shifts in biofilm structure and microbial succession during the early stages of biofilm formation. Trisodium citrate dihydrate 294.10 [6132-04-3]. Sodium citrate may be used in all types of cosmetic products, including baby products, make-up, lipstick, bath products, soaps and detergents, hair dyes and colors, and hair and skin care products. In contrast, Biofilms grown in the absence of sodium citrate were characterized as homogenously spread microcolonies and aggregates that gradually colonized the surface from day 7 to day 28 of the experiment.

FEMS Microbiol. The structure and microbial community composition of biofilms in the absence and presence of sodium citrate were compared at different time points of their early-stage formation. Appl Environ Microbiol. https://doi.org/10.1177/0022034513504218 (2013). Such a shift in the microbial community structure may be attributable to the fact that some genera under Proteobacteria favor citrate as their sole carbon source such as Salmonella43. Screening for species annotation to obtain a representative sequence for each OTU was performed using the GreenGene Database36 based on RDP Classifier37. We found that the × 40 objective was ideal for acquiring control biofilms stacks, however, the same objective used on biofilm supplemented with sodium citate led to loosing intricate details of the biofilm’s structural properties, which were best observed using a 20 × objective. Appl. Y.Y., Y.P., W.Y.N., K.K., and J.P. collected the data. The potential biases in biofilms grown in supplemented media include shifts in the biofilm structure and microbial composition compared with those in biofilms grown in non-supplemented media. Article  While sodium citrate is likely to accelerate biofilm development in multispecies biofilms, how substrate addition may affect experimental outcomes in terms of biofilm structure and microbial community composition remains unclear, thereby causing potential experimental biases. Lett. In multispecies biofilm models, we hypothesized that the addition of sodium citrate may alter the multispecies community composition as well as its microbial succession. Trisodium citrate has the chemical formula of Na 3 C 6 H 5 O 7. The authors acknowledge with gratitude the generous support received from the University Grants Committee for this project (RGC Ref No. Nat. 3 for biofilms grown in the presence and absence of sodium citrate (NaCi and Control, respectively).

From farm-scale to lab-scale: the characterization of engineered irrigation water distribution system biofilm models using an artificial freshwater source. Compared with biofilms in sodium citrate conditions (average degree = 12), those in control conditions showed a more complex network interconnection with an average of 13.8 (average degree) connections per node. To determine the effect of sodium citrate supplementation on fresh water biofilm structure over a four-week period, biofilms were harvested using two ABR systems run in parallel, one under the presence and another under the absence of sodium citrate (NaCi and control). Res. The hypothesis was that citrate (sodium citrate) injection would affect cheese properties mainly through its effect on bound calcium (calculated as the difference between total calcium and the water-soluble calcium content of a cheese extract). Statistical methods including t-test, MetaStat (calculated using R), LEfSe (calculated by LEfSe software), Anosim (performed using R), and MRPP (performed using R) were used to assess the significance of differences in the structure and microbial community composition between the groups. The edge font is proportional to the number of supported methods that presented significant correlation (p < 0.05). This is a natural preservative and is also used in foods and soft drinks to give an acidic (sour) flavour. 6, 705. https://doi.org/10.3389/fmicb.2015.00705 (2015). & Wolfaardt, G. M.

Under sodium citrate conditions, the total biovolume was 50 times (p < 0.01) and 100 times (p < 0.01) higher on day 7 and 28 than that on the corresponding days under control conditions, which is 1.6 × 104, and 5.7 × 104 µm3, respectively. Black and red edges represent positive and negative correlations, respectively. In experiments involving the use of nonsterile medium, the issue of repeatability or inconsistent biofilm outcomes may arise due to the dynamic chemical conditions of the natural source and the high diversity of initial microorganisms. https://doi.org/10.1016/j.archoralbio.2013.06.017 (2013).

Furthermore, the highest number of co-inclusion interactions was shown by the TM6 (Dependentiae) phylum (positive degree = 6) in the interaction network of biofilms grown under sodium citrate conditions and by the Chloroflexi phylum (positive degree = 10) in that of biofilms grown under control conditions. https://doi.org/10.1038/nmeth.2276 (2013).

Each ABR could hold up to 40 coupon surfaces made of stainless steel on which biofilms could be harvested for systematic analysis. Nevertheless, one of the caveat of performing in vitro experiments is associated with the choice of growth medium, regardless of which type of monospecies or multispecies biofilm model is being investigated.
