Sentence examples for microbial operational from inspiring English sources

26 However, in many cases the apparent assignment of a microbial operational taxonomic unit (OTU) was in fact an attribute of sequencing errors, which caused an overinflation of the diversity estimates.

Through statistical comparison of individual microbial operational taxonomy units (OTUs), combined with several objective selection criteria, several candidate organisms were identified as candidates that may have played a role in the observed yield decline.

Microbial operational taxonomic units (OTUs) and their taxonomic assignments were obtained using default settings in QIIME version 1.8 [ 22] by reference-mapping at 97% similarity against representative sequences of 97% OTU in Greengenes (taxa version 4feb2011; metagenome version 12_10) [ 23].

Vaziri et al. [ 6], using microarray analysis, observed significant differences in the abundance of 190 microbial operational taxonomic units (OTU) between healthy individuals and haemodialysis patients, who presented an increased abundance of Enterobacteriaceae, particularly the OTUs containing certain clusters of E. coli sequences.

We processed microbial community and operational data from controlled experiments with bench-scale bioreactor systems to predict reactor process performance.

These diversity indices were then used to train and test a support vector regression (SVR) model to predict reactor performance based on input microbial community indices and operational data.

Therefore, the objective of this study was to understand the responses of microbial communities to different operational conditions of anaerobic co-digestion and their influences on biogas production and solid digestate quality.

In contrast to other microbiological methods, currently there are no regular proficiency testing programs operational for microbial residue screening methods, while these are considered highly necessary to reveal the inevitable shortcomings in this area.

Maximum acceptable levels were taken as the standards determined by ISPESL in 2009 for air microbial contamination in operating theatres with turbulent air flow: ≤ 35 CFU/m at rest and ≤ 180 CFU/m in operational[ 30].

Here we show that a dysbiotic expansion of Enterobacteriaceae during gut inflammation could be prevented by tungstate treatment, which selectively inhibited molybdenum-cofactor-dependent microbial respiratory pathways that are operational only during episodes of inflammation.

In spite of its potential, this technology needs further research and development to improve the biohydrogen yield by optimizing substrate utilization, microbial community enrichment and bioreactor operational parameters such as pH, temperature and H2 partial pressure.
