Circular utilization of food waste to biochar enhances thermophilic co-digestion performance

Advances, trends and challenges in the use of biochar as an improvement strategy in the anaerobic digestion of organic waste: a systematic analysis

“…[ 64 ] In contrast, sludge or manure is less used. [ 40 ] This is associated with the fact that the lignocellulosic waste used has a low moisture content, which facilitates the production of BC. In addition, during the obtaining process, a BC of very good quality is achieved [ 99 ], which is characterized by the generation of high molecular weight polycyclic aromatic hydrocarbons (PAH), a characteristic that helps to achieve a BC with a higher specific surface; in addition to the presence of minerals and a variety of functional groups, which makes it an effective adsorbent.…”

H2 mediated mixed culture microbial electrosynthesis for high titer acetate production from CO2

“…Genomic DNA was extracted from the samples using DNeasy PowerSoil Pro kit (QIAGEN). The preparation of the library and the paired-end amplicon sequencing of the V4 region of the 16S rRNA gene were carried out according to previously described methods [ 28 ]. Sequencing analyses were conducted in R using the DADA2 pipeline to obtain amplicon sequence variants (ASVs) [ 29 ].…”

Molecular transformation and metabolic insights of microbial electrolysis treatment and valorization of post-hydrothermal liquefaction wastewater

“…Prior to imaging, the carbon brush samples were dried and then sputter coated with approximately 3 nm of iridium (Leica EM ACE600). 19…”

“…Prior to imaging, the carbon brush samples were dried and then sputter coated with approximately 3 nm of iridium (Leica EM ACE600). 19 When conducting MEC experiments using PHW as feedstock, we first diluted PHW using PBS with different dilution ratios (10×, 20× and 40×) as noted in the results section. Different concentrations of PBS ( pH = 7.05 ± 0.05) were tested: 20 mM, 50 mM, and 100 mM.…”
