The consolidated bioprocessing (CBP) of corn stover pretreated via ammonia fiber expansion (AFEX-CS) into ethanol was investigated in a microbial electrolysis cell (MEC) driven by the exoelectrogen Geobacter sulfurreducens and the CBP bacterium Cellulomonas uda. C. uda was identified in a screening for its ethanologenic potential from AFEX-CS and for producing electron donors for G. sulfurreduc...

Endoglucanase C (CenC), a beta1,4 glucanase from the soil bacterium Cellulomonas fimi, binds to amorphous cellulose via two homologous cellulose binding domains, termed CBD(N1) and CBD(N2). In this work, the contributions of 10 amino acids within the binding cleft of CBD(N1) were evaluated by single site-directed mutations to alanine residues. Each isolated domain containing a single mutation w...

The diversity of bacterial isolates from soil in response to different plants (control, Brachiaria ruziziensis and Cajanus cajan), fertilization (control, simple superphosphate and rock phosphate) and liming (with and without lime) was evaluated. Phenotypic and physiological characteristics of the isolates were recorded and organized in a file to identify the bacteria. Among the isolates, 95% w...

Cellulomonas sp. JZ18 is a gram-positive, rod shaped bacterium that was previously isolated from the root endosphere of perennial desert tussock-grass Panicum turgidum. Genome coverage PacBio sequencing approximately 199X. assembly generated single chromosome 7,421,843 base pairs with guanine-cytosine (GC) content 75.60% 3240 protein coding sequences, 361 pseudo genes, three ribosomal RNA opero...
