Enhancing the performance of E. coli-powered MFCs by using porous 3D anodes based on coconut activated carbon

In this study, activated carbon felt (C3P1AC1) fabricated by combining coconut-shell activated carbon powder (CSAC), carbon fiber, and cellulose fiber was used as the anode electrode in an Escherichia coli (E. coli) biofilm-inoculated MFC. CSAC ratio in the C3P1AC1 anodes was varied from 0 to 75 wt%, called C3P1AC1-X (X = 0, 10, 20, 40, 60, and 75), to investigate the effectiveness of CSAC on the performance of the anode. The C3P1AC1 anodes were characterized by XRD, SEM, EDS, and sheet resistance measurement. The maximum power density of the MFC has increased 7.2-fold from 0.53μWcm-2 when using the C3P1AC1-0 anode to 3.8 μWcm-2 when using the C3P1AC1-10 anode; it has further increased 9.1-fold as the CSAC ratio increased from 10 wt% to 60 wt%. However, when the CSAC ratio increased further to 75 wt%, the maximum power density decreased by 32.9 %. This result was attributed to the sheet resistance of the C3P1AC1-75 anode increased by 86 % if compared with that of the C3P1AC1-60 anode.Graphical Abstract

Gut bacterial dysbiosis emerges as a leading cause of post-weaning diarrhea. The present study was aimed to investigate the effect of capsulized fecal microbiota transportation (FMT) on gut bacterial community, immune response and gut barrier function of weaned piglets. Thirty-two were randomly divided into two groups fed with basal diet for 21 days. Recipient group was inoculated orally with capsulized fecal microbiota of health Tibetan pig daily morning duri...

These include gpD-fusions to human and porcine cathelicidins LL37 and PR39, &am...

Potential risk factors for colonization with AMRB/MSSA and the potential effects of colonization with these on the obstetric population were investigated.MethodsFrom October 2013 until December 2015 pregnant women were screened before birth for colonization with AMRB/MSSA from the mammillae, nose, perianal and vaginal area. Before birth, the expectant mother was administered a standardized interview questionnaire by a trained interviewer. Data from the hospi...
