Multicriteria Analysis of the Effects of Field Burning Crop Residues
Burning crop residues is frequently used by Romanian land users to clean agricultural fields after crop harvest for ease in post-harvest soil tillage. Huge amounts of crop residues biomass, on very large areas, were burned in Romania in the last twenty ...

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Harvesting crop residues for alcohol production
An estimated 7 to 15 percent of energy now used in California could come from cellulosic biomass, if fully utilized. From 20 to 35 million tons of this underutilized residue from forest and farming operations are produced annually in California ...

Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Growth and yield parameters of white oat and wheat as affected by canola residues
Despite being an important crop option for Brazilian agriculture, canola has some characteristics that may limit its insertion in some cropping systems, such as its allelopathic effects.

Dispersion is essential in crop residue application [PDF]
Background Crop residue application can maintain soil fertility and sustain agriculture. However, the effects of residue application are unstable because of variable weather conditions and the residual effects of crop residue application. Furthermore, residue application often reduces crop yields.

Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Research with nitrogen fertilizer emphasizes fertilize crop—not crop residue
1. Results of field experiments indicate that it is more efficient and effective to apply nitrogen to the crop than to previous crop residues months ahead of planting the crop. 2.

Organic producers have few certified organic options to meet crop nitrogen (N) demand. Poultry-based amendments, including manures and processed fertilizers from livestock waste (e.g., feather meal), are commonly used in these systems, but synchronizing ...
