Process hygiene plays a major role in the production of high quality beer. Knowledge of microorganisms found in the brewery environment and the control of microbial fouling are both essential in the prevention of microbial spoilage of beer. The present study examined the growth of surface-attached beer spoilage organisms and the detection and elimination of microbial biofilms. Moreover, the det...

Microbe-host interactions are complex processes that are directly and indirectly regulated by a variety of factors, including microbe presentation of specific molecular signatures on the microbial surface, as well as host cell presentation of receptors that recognize these pathogen signatures. Cell surface glycans are one important class of microbial signatures that are recognized by a variety ...

aim and background: complex nature of children`s affectionate problems requires assessment and usage of modern treatments. the present study aimed to investigate the effects of attachment-based therapy on depression symptoms in girl students of primary school who had attachment problems. methods and materials: this study was an empirical plan with pretest-posttest, follow up and control group. ...

Biofilm is an assemblage of the microbial cells that is irreversibly associated with a surface and usually enclosed in a matrix of polysaccharide material. Biofilm is composed primarily of microbial cells and extracellular polymeric substance (EPS). Extracellular polymeric matrix plays various roles in structure and function of different biofilm communities. Adhesion to the surface provides con...

Mechanisms of Escherichia coli attachment on biofilms grown on PVC coupons were investigated. Biofilms were grown in CDC reactors using groundwater as feed solution over a period up to 27 weeks. Biofilm physical structure was characterized at the micro- and meso-scales using Scanning Electron Microscopy (SEM) and Optical Coherence Tomography (OCT), respectively. Microbial community diversity wa...

Intravascular catheters (IVCs) are the most frequently used medical devices in hospitals. However, they are associated with life-threatening IVC-related bloodstream infection (IVC-BSI), which is one of the main hospital-acquired infections, and continue to be associated with morbidity, mortality and additional medical cost. Most published studies focus on measuring the rate of IVC-BSIs and addr...

We report a novel microfluidic microbial fuel cell (μMFC) with an improved design of 3D bioanode. The device features a highly conductive, multilayered nanofibrous anode providing a porous scaffold structure favorable for microbial attachment, mass transfer, and electron collection. The anolyte and catholyte chambers have a small volume of 2 μL each, and are separated by a proton exchange membr...

Understanding the interactions of plant-parasitic nematodes with antagonistic soil microbes could provide opportunities for novel crop protection strategies. Three arable soils were investigated for their suppressiveness against the root knot nematode Meloidogyne hapla. For all three soils, M. hapla developed significantly fewer galls, egg masses, and eggs on tomato plants in unsterilized than ...

A large array of glycoproteins, glycolipids, and proteoglycans decorate the surfaces of animal cells. These glycoconjugates mediate many fundamental cellular processes, including cell-cell and cell-matrix adhesion, motility, growth, and signaling (28, 110). Over time, many pathogenic microorganisms have learned to exploit cell surface glycoconjugates as receptors for attachment, a process which...
