the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...
Mass spectrometry (MS) in Selected Reaction Monitoring (SRM) mode is proposed for in-depth characterisation of microorganisms in a multiplexed analysis. Within 60-80 minutes, the SRM method performs microbial identification (I), antibiotic-resistance detection (R), virulence assessment (V) and it provides epidemiological typing information (T). This SRM application is illustrated by the analysi...
Current thinking on the development of molecular microbial characterisation techniques in public health focuses mainly on operational issues that need to be resolved before incorporation into daily practice can take place. Notwithstanding the importance of these operational challenges, it is also essential to formulate conditions under which such microbial characterisation methods can be used f...
Bacteria are often maligned as the cause of human and animal diseases. Despite this characterisation, certain bacteria such as Acetobacter sp. and lactic acid bacteria were found to produce polysaccharides, function as antibiotics and find use as food additives (Sutherland, 2001). Over the past 20 years, a new class of microbial product – microbial polysaccharide – has been grown for industrial...
Analysis of microbial communities associated with plants, insects and soil has been a significant challenge for plant protection researchers, because of the lack of techniques with which to access these populations. A new molecular community profiling technique, 16S rRNA gene-based PCR followed by denaturing gradient gel electrophoresis (DGGE), has been used to analyse microbial communities in ...
Tuberculosis is a major cause of death but infected people with effective immunity may remain healthy for years, suggesting long-term co-existence of host and pathogen. Direct detection and characterisation of ancient microbial DNA and lipid biomarkers confirms palaeopathological diagnoses. Archaeological Mycobacterium tuberculosis resembles extant lineages indicating the timescale for evolutio...
This study demonstrates mathematical description of sewage sludge composting based on identification and separate characterisation of simple process parts. For a description of the microbial processes an aSM3-based mathematical model developed for autothermal thermophilic aerobic sludge digestion is used. The oxygen mass transfer was characterized in a separate way. The 2.964·10-3 m2·d-1 value ...
With multiplex oligonucleotide ligation-PCR (MOL-PCR) different molecular markers can be simultaneously analysed in a single assay and high levels of multiplexing can be achieved in high-throughput format. As such, MOL-PCR is a convenient solution for microbial detection and identification assays where many markers should be analysed, including for routine further characterisation of an identif...
Although some evidence on the structural characteristics of in situ early PL-biofilm has been described, there are few studies on the antibacterial effects of agents on this microbial structure. A major application of advanced microbiological and/or microscopy techniques, in combination with CLSM, needs to be exploited in future research in order to increase knowledge of the global characterisa...
