Lignin is a heterogeneous polymer of aromatic subunits that major component lignocellulosic plant biomass. Understanding how microorganisms deconstruct lignin important for understanding the global carbon cycle and could aid in developing systems processing biomass into valuable commodities. Sphingomonad bacteria use stereospecific glutathione S-transferases (GSTs) called β-etherases to cleave β-aryl ether (β-O-4) bond, most common bond between lignin. Previously characterized bacterial are...
Organic-rich industrial residues can serve as renewable feedstocks for the generation of useful products by microbial fermentation. We investigated fermenting communities enriched in a mixture ultra-filtered milk permeate (UFMP) and acid whey from cottage cheese (CAW), two dairy coproducts rich lactose. To evaluate how operational pH temperature affect fermentation products, we operated 12 bioreactors 140 days, each fed 1:1 UFMP CAW at either 35 °C or 50 4.8 5.5. The resulted incomplete...
The liquid residue resulting from various agroindustrial processes is both rich in organic material and an attractive source to produce a variety of chemicals. Using microbial communities chemicals these residues active area research, but it unclear how deploy specific products the different residues. To address this, we fed anaerobic bioreactors one several (carbohydrate-rich lignocellulosic fermentation conversion residue, xylose, dairy manure hydrolysate, ultra-filtered milk permeate,...
Fermentative microbial communities have the potential to serve as biocatalysts for conversion of low-value dairy coproducts into renewable chemicals, contributing a more sustainable global economy. To develop predictive tools design and operation industrially relevant strategies that utilize fermentative communities, there is need determine genomic features community members are characteristic accumulation different products. address this knowledge gap, we performed 282-day bioreactor...
Dairy manure (DM) is an abundant agricultural residue that largely composed of lignocellulosic biomass. The aim this study was to investigate if carbon derived from DM fibers can be recovered as medium-chain fatty acids (MCFAs), which are mixed culture fermentation products economic interest. were subjected combinations physical, enzymatic, chemical, and thermochemical pretreatments evaluate the possibility producing carbohydrate-rich hydrolysates suitable for microbial by cultures. Among...
To advance knowledge of microbial communities capable fermenting agro-industrial residues into value-added products, we report metagenomes from six anaerobic bioreactors that were fed a mixture ultra-filtered milk permeate and cottage cheese acid whey. These produced 122 metagenome-assembled genomes represent 34 distinct taxa.
Fermentative microbial communities can be utilized for the conversion of various agroindustrial residues into valuable chemicals. Here, we report 34 metagenomes from anaerobic bioreactors fed lactose-rich ultrafiltered milk permeate and 278 metagenome-assembled genomes (MAGs). These MAGs inform future studies aimed at generating renewable chemicals dairy other residues.
Here, we report the metagenomes from five anaerobic bioreactors, operated under different conditions, that were fed carbohydrate-rich thin stillage a corn starch ethanol plant. The putative functions of abundant taxa identified here will inform future studies microbial communities involved in valorizing this and other low-value agroindustrial residues.
Anaerobic microbiomes can be used to recover the chemical energy in agroindustrial and municipal wastes as useful products. Here, we report a total of 109 draft metagenome-assembled genomes from bioreactor-fed carbohydrate-rich dairy manure hydrolysate. Studying these will aid us deciphering metabolic networks anaerobic microbiomes.
