In that respect, it is notable that very low levels of N. aromaticivorans, as detected by PCR, persisted for several weeks after the bulk of the original microbial inoculum was cleared, perhaps providing continuous fuel for NKT cell activation, and that antibiotic treatment during that period prevented the evolution of chronic cellular and humoral autoimmunity.
The microbial inoculum was stabilized over a period of 2-wk on a carbohydrate-based medium and allowed to adapt to the specific environmental conditions of the ascending, transverse and descending colon, in terms of pH range, retention time and available carbon sources [ 14, 15].
The concentrations of microbial inoculums were adjusted to 2.5 × 105 colony-forming units (CFU) per mL as measured with the McFarland turbidity standards using spectrophotometer at 600 nm.
Two samples from digesters fed with NS1 and NS2, respectively, at I/ S ratio of 1 without calcium addition as well as original inoculum were subject to microbial community structure analysis.
The substrates and inoculum were mixed at the ratio of 1 2 in terms of gram VS [17] to avoid potential substrate inhibition and low microbial density.
The effect of temperature on a miniaturized microbial fuel cell with Geobacter sulfurreducens dominated mixed inoculum is investigated in this paper for the first time.
A dual-chambered microbial fuel cell, fed with slaughterhouse wastewater with an anaerobic mixed sludge as a source of inoculum was used.
The above-mentioned microbial suspensions were further diluted to 1 100 in media, and a 100 μl volume of this diluted inoculum was added to each well of the plate, resulting in a final inoculum of 1.5×10 cfu/ml for bacteria, 1.5×10 cfu/ml for A. fumigatus and 1.5×10 cfu/ml for yeasts.
