Can cadmium-contaminated rice be used to produce food additive sodium erythorbate?

Cadmium (Cd) in rice is a significant concern for its quality and safety. Currently, there is a crucial need to develop cost-effective and efficient ways to remove Cd or re-utilize Cd-contaminated rice. The food additive sodium erythorbate is produced via 2-ketogluconic acid (2KGA) fermentation by Pseudomonas plecoglossicida and lactonization using starch-rich raw materials, such as rice.

Leaf shape, planting density, and nitrogen application affect soybean yield by changing direct and diffuse light distribution in the canopy.

When attempting to maximize the crop yield from field-grown soybean (Glycine max (L.) Merr.) by means of improving the light conditions for photosynthesis in the canopy, it is crucial to find the optimal planting density and nitrogen application rate.

Proteomic analysis of protein lysine 2-hydroxyisobutyrylation (K) in soybean leaves.

Background: Protein lysine 2-hydroxyisobutyrylation (K) is a novel post-translational modification (PTM) discovered in cells or tissues of animals, microorganisms and plants in recent years. Proteome-wide identification of K-modified proteins has been performed in several plant species, suggesting that K-modified proteins are involved in a variety of biological processes and metabolic pathways. However, the protein K modification in soybean, a globally important legume crop that provides the rich source of plant protein and oil, remains unclear.

Leguminous cover crops and soya increased soil fungal diversity and suppressed pathotrophs caused by continuous cereal cropping.

The enrichment of soil-borne fungal pathogens and a high input of mineral fertilizer in the continuous cropping of cereal crops have raised a concern about soil health deterioration. Conversion of continuous cereal cropping to a legume-involved system alters the soil fungal community. However, when a leguminous cover crop is grown with a succeeding legume grain crop such as soya (), the effects on the soil fungal community when two legumes are involved in the crop system remain unclear.

Pseudomonas tumuqii sp. nov., isolated from greenhouse soil.

A Gram-stain-negative, aerobic, rod-shaped and motile bacterium, named LAMW06, was isolated from greenhouse soil in Beijing, China. In the 16S rRNA gene sequence comparison, strain LAMW06 had the highest similarity with Pseudomonas cuatrocienegasensis 1N. Phylogenetic analysis based on the 16S rRNA and three housekeeping gene sequences (gyrB, rpoB and rpoD) indicated that strain represented a member of the genus Pseudomonas.

Semi-continuous production of 2-keto-gluconic acid by Pseudomonas fluorescens AR4 from rice starch hydrolysate.

2-Keto-gluconic acid (2KGA) was produced in a semi-continuous process using Pseudomonas fluorescens AR4 and rice starch hydrolysate (RSH). The bacterium was cultured in medium with an initial glucose concentration of 170g/L supplied as RSH. Once the glucose level had dropped to 20g/L, 60% of the culture volume was replaced with fresh medium containing 190g/L of glucose in the form of RSH.
