Effect of sulfate on low-temperature anaerobic digestion
(Frontiers Media, 2014-07-24)The effect of sulfate addition on the stability of, and microbial community behavior in, low-temperature anaerobic expanded granular sludge bed-based bioreactors was investigated at 15 degrees C. Efficient bioreactor ... -
Eight rules for improving the quality of papers on the antimicrobial susceptibility of bacteria isolated from aquatic animals
(Inter-Research Science Publisher, 2020-04-30)The methods for antimicrobial susceptibility testing of bacteria, although relatively simple, are not robust. As a consequence, if the data generated in such tests are to be commensu- rate, all susceptibility tests must ... -
Engineering recombinant antibodies for polymer biofunctionalization
(Wiley, 2015-08-18)The attachment of recognition elements such as antibody fragments to polymeric substrates can be used to mediate cell- or protein-specific interactions. In this work, single-chain Fv (scFv) antibody fragments were isolated ... -
Examination of oestrus-dependent alterations of bovine cervico-vaginal mucus glycosylation for potential as optimum fertilisation indicators
(Royal Society of Chemistry, 2021-03-09)Oestrus is the period in the sexual cycle of female mammals during which ovulation occurs, where they become most receptive to mating and are most fertile. Efficient detection of oestrus is a key component in successful ... -
Fermentative hydrogen production from cheese whey with in-line, concentration gradient-driven butyric acid extraction
(Elsevier, 2020-08-01)Hydrogen (H2) generation from cheese whey with simultaneous production and extraction of volatile fatty acids (VFAs) was studied in UASB reactors at two temperatures (20 and 35 °C) and pH values (5.0 and 4.5). The extraction ... -
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press, 2015-10-27)Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ... -
Generation of a panel of high affinity antibodies and development of a biosensor-based immunoassay for the detection of okadaic acid in shellfish
(Elsevier, 2015-07-10)Okadaic acid (OA) and its derivatives, DTX-1 and DTX-2, are marine biotoxins associated with diarrhetic shellfish poisoning. Routine monitoring of these toxins relies on the mouse bioassay. However, due to the technical ... -
Geographical location influences the composition of the gut microbiota in wild house mice (Mus musculus domesticus) at a fine spatial scale
(Public Library of Science, 2019-09-26)The composition of the mammalian gut microbiota can be influenced by a multitude of environmental variables such as diet and infections. Studies investigating the effect of these variables on gut microbiota composition ... -
Glycomics microarrays reveal differential in situ presentation of the biofilm polysaccharide Poly-N-acetylglucosamine on Acinetobacter baumannii and Staphylococcus aureus cell surfaces
(MDPI, 2020-04-02)The biofilm component poly-N-acetylglucosamine (PNAG) is an important virulence determinant in medical-device-related infections caused by ESKAPE group pathogens including Gram-positive Staphylococcus aureus and Gram-negative ... -
Identification of Components of the Sigma B Regulon in Listeria monocytogenes That Contribute to Acid and Salt Tolerance
(American Society for Microbiology, 2008-09)Sigma B is an alternative sigma factor that controls the transcriptional response to stress in Listeria monocytogenes and is also known to play a role in the virulence of this human pathogen. In the present study we ... -
Identification of putative adhesins and carbohydrate ligands of Lactobacillus paracasei using a combinatorial in silico and glycomics microarray profiling approach
(Oxford University Press (OUP), 2019-11-11)Commensal bacteria must colonize host mucosal surfaces to exert health-promoting properties, and bind to gastrointestinal tract (GIT) mucins via their cell surface adhesins. Considerable effort has been directed towards ... -
Impact of trichloroethylene exposure on the microbial diversity and protein expression in anaerobic granular biomass at 37°C and 15°C
(Hindawi Publishing Corporation, 2012-09-14)Granular biomass from a laboratory-scale anaerobic bioreactor trial was analysed to identify changes in microbial community structure and function in response to temperature and trichloroethylene (TCE). Two bioreactors ... -
In vitro comparative cytotoxicity study of a novel biocidal iodo-thiocyanate complex
(Elsevier, 2018-04-03)Novel biocides, which avoid the induction of cross-resistance to antibiotics, are an urgent societal requirement. Here, we compared the cytotoxic and bactericidal effects of a new antimicrobial agent, the iodo-thiocyanate ... -
Influence of incubation time on antimicrobial susceptibility testing of pathogenic Vibrio anguillarum and Vibrio vulnificus isolated from fish
(Elsevier, 2020-07-15)A multi-laboratory study was performed to investigate the most suitable incubation time for susceptibility tests of fish pathogens Vibrio anguillarum and Vibrio vulnificus performed at 28 degrees C. An isolate set consisting ... -
Influence of stormflow and baseflow phosphorus pressures on stream ecology in agricultural catchments
(Elsevier, 2017-03-09)Stormflow and baseflow phosphorus (P) concentrations and loads in rivers may exert different ecological pressures during different seasons. These pressures and subsequent impacts are important to disentangle in order to ... -
Intracellular accumulation of high levels of gamma-aminobutyrate by Listeria monocytogenes 10403S in response to low pH: uncoupling of gamma-aminobutyrate synthesis from efflux in a chemically defined medium
