Pectobacterium carotovorum (PBC) is a major plant pathogen responsible for soft rot disease in peppers, and its prevention and control remain highly challenging. In this study, a novel lytic phage targeting Pectobacterium carotovorum subsp. carotovorum (PCC), designated as Pcc_P10, belonging to the Pektosvirus genus within the Autographiviridae order, was isolated and characterized.

In response, phage therapy has reemerged as a promising alternative to conventional antibiotics. In this study, two lytic bacteriophages, Kpn_PImp2 and Kpn_PImp3, were isolated from urban sewage, a rich source of phages owing to its diverse microbial community.

To alleviate this limitation, phosphorus-solubilizing bacteria (PSB) play a crucial role by converting insoluble phosphates present in the soil into soluble forms that are accessible to plants. Wangerin is a representative oil crop cultivated in red soil, holding a prominent position within China's forestry economic system.

- Nitrogen is a crucial nutrient for crop growth, particularly for winter wheat in the North China Plain, where its yield has significantly increased over the past 20 years.
- A field experiment tested five different nitrogen application rates to assess their impact on crop yield and efficiency during the 2017-2019 winter wheat seasons.
- The study found that applying 200 kg N per hectare maximized crop yield and nutrient efficiency, recommending a balanced distribution of nitrogen during key growth stages for optimal results.
Free-Standing Metal-Organic Framework Membranes Made by Solvent-Free Space-Confined Conversion for Efficient H/CO Separation.
ACS Appl Mater Interfaces
April 2023
Article Synopsis
- Metal-organic frameworks (MOFs) are effective materials for membranes due to their adjustable structures and pore sizes, but traditional synthesis methods are inefficient and environmentally challenging.
- A new method called solvent-free space-confined conversion (SFSC) allows for the creation of free-standing MOF membranes without the need for solvents or supports, making the process more sustainable and efficient.
- The resulting membranes demonstrate impressive hydrogen permeance and selectivity, with specific examples showing high performance, indicating that this method could lead to scalable production for gas separation applications.
Room-Temperature Preparation of Covalent Organic Framework Membrane for Nanofiltration.
Macromol Rapid Commun
June 2023
Article Synopsis
- - The unique properties of covalent organic frameworks (COFs), such as customizable pore size and stability, make them ideal candidates for creating effective membrane separations.
- - Researchers have successfully developed a P-COF membrane on a porous alumina substrate at room temperature, achieving 99.7% rejection of rhodamine B and high water permeance, showcasing effective wastewater purification.
- - This new method of fabricating COF membranes at room temperature is more energy-efficient than traditional approaches and enhances the membrane's strength, presenting a significant step towards environmentally friendly and effective nanofiltration solutions.
Article Synopsis
- - Grape hyacinth plants accumulate specific anthocyanins, mainly delphinidin and cyanidin, due to the unique expression of their dihydroflavonol 4-reductase (MaDFR) gene, which helps produce blue pigments rather than red ones.
- - The study found that MaDFR efficiently reduces various dihydroflavonols, especially favoring dihydromyricetin to generate leucodelphinidin, highlighting other genes may influence the absence of red pigments in these flowers.
- - Amino acid mutations in MaDFR showed that specific sites (N135 and E146) are crucial for enzyme activity, and expression of this gene in tobacco enhanced anthoc
Article Synopsis
- A new and effective ZIF membrane was created for removing dyes from solutions.
- The membrane has a unique pore structure and a thin layer that enhances its ability to separate dyes from water.
- It achieved over 99.8% dye rejection and maintained a high water flow rate of approximately 100 liters per square meter per hour.
