Abstract: The sustainable recovery of resources from wastewater streams can provide many social and environmental benefits. A common strategy to recover valuable resources from wastewater is to harness the products of fermentation by complex microbial communities. In these fermentation bioreactors high microbial community diversity within the inoculum source is commonly assumed as sufficient for the selection of a functional microbial community. However, variability of the product profile obtained from these bioreactors… Show more

“…Whether such bacteria are initially present in the incoming feed is a matter of future investigation. Similar observations were made in an earlier study that demonstrated how the incoming feed shapes the microbial community structure in anaerobic digesters [49], through the use of different microbial inoculants. Our study here argues that the microbial community present in the incoming feed is influenced by local environmental conditions, which consequently play important roles in shaping the microbial community in anaerobic digesters.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The three fecal sample used in the experiment evolved differently during the fermentation, resulting in differences in cultured families or genera. The influence of the initial complex microbial community was previously demonstrated in batch fermentation cultures ( Perrotta et al, 2017 ; Van den Abbeele et al, 2018 ). The fermentation led to dissimilarities between the cultured samples and baselines, a phenomenon that was previously observed in a comparable 24-well in vitro fermentation system ( O’Donnell et al, 2018 ).…”

“…The parameter

Y_{{italicCH}_{4} / X_{m}}

also shows high sensitivity on the CH 4 production. It is important to note that the significant change occurs in the yield coefficient

Y_{{italicCH}_{4} / X_{m}}

, and this was expected because the microorganisms adapt their metabolism in each batch, 52 that is, in each batch operation, the methanogenic microorganisms adapt to increase CH 4 production. While the variation of the parameter K A is associated with the affinity that the acidogenic microorganisms present to the substrate S 2 , these variations are reflected in the process performance.…”
