Bioaugmentation of anaerobic digesters treating lignocellulosic feedstock by enriched microbial consortia

Effect of shear on performance and microbial ecology of continuously stirred anaerobic digesters treating animal manure.

We determined the effect of different mixing intensities on the performance, methanogenic population dynamics, and juxtaposition of syntrophic microbes in anaerobic digesters treating cow manure from a dairy farm. Computer automated radioactive particle tracking in conjunction with computational fluid dynamics was performed to quantify the shear levels locally. Four continuously stirred anaerob...

Anaerobic Decomposition of Switchgrass by Tropical Soil-Derived Feedstock-Adapted Consortia

UNLABELLED Tropical forest soils decompose litter rapidly with frequent episodes of anoxic conditions, making it likely that bacteria using alternate terminal electron acceptors (TEAs) play a large role in decomposition. This makes these soils useful templates for improving biofuel production. To investigate how TEAs affect decomposition, we cultivated feedstock-adapted consortia (FACs) derived...

Biological Conversion of Normal Chain Octadecane by Native Microbial Consortia

"> Long-chain alkanes are a major constituent of crude oils and their conversions into other compounds are of interest depending on the specific application. Here, five <span style="font-size: 9pt; color...

Raman Imaging of Lignocellulosic Feedstock

The main structural plant cell wall polymers cellulose, hemicelluloses, and lignin rank amongst the most abundant biopolymers in Earth’s carbon cycle. These three polymers form the lignocellulose complex and constitute the bulk of the cell wall with 40-50%, 10-40% and 5-30% of biomass by weight, respectively [1, 2]. Its highly ordered structure of cellulose microfibril aggregates, embedded in a...
