Development of a quinic acid-induced CRISPR/Cas9 genome editing system and its application for the activation of ilicicolin H biosynthesis in Trichoderma reesei.

The CRISPR/Cas9 genome editing tool has been extensively utilized in filamentous fungi, including Trichoderma reesei. However, most existing systems employ constitutive promoters for the expression of Cas9 protein within the cells or directly introduce Cas9 protein into the cells, which often leads to continuous expression of Cas9 resulting in undesired phenotypes or increased operational cost. In this study, we identified a quinic acid (QA)-induced qai5 promoter and employed it to express Cas9, thereby establishing an inducible genome editing system in T.

High-Sensitivity Differential Sensor for Characterizing Complex Permittivity of Liquids Based on LC Resonators.

This paper proposes a high-sensitivity microstrip differential sensor for measuring the complex permittivity of liquids. The prototype of the differential sensor was formed by cascading two LC resonators on a microstrip transmission line based on stepped impedance. A strong electric field was found to be distributed in the circular patch of the LC resonator; therefore, a cylindrical micropore was set in the center of the circular LC resonator to measure the dielectric sample, which maximized the disturbance of the dielectric sample on the sensor.

Multifaceted regulation of siderophore synthesis by multiple regulatory systems in Shewanella oneidensis.

Siderophore-dependent iron uptake is a mechanism by which microorganisms scavenge and utilize iron for their survival, growth, and many specialized activities, such as pathogenicity. The siderophore biosynthetic system PubABC in Shewanella can synthesize a series of distinct siderophores, yet how it is regulated in response to iron availability remains largely unexplored. Here, by whole genome screening we identify TCS components histidine kinase (HK) BarA and response regulator (RR) SsoR as positive regulators of siderophore biosynthesis.

The control of dry-out patterns using bubble-containing droplets.

Hypothesis: For an evaporating nanofluid droplet that contains a bubble inside, we suspect the bubble boundary remains pinned during evaporation whereas the droplet perimeter recedes. Thus, the dry-out patterns are mainly determined by the presence of the bubble and their morphology can be tuned by the size and location of the added bubble.

Experiments: Bubbles with varying base diameters and lifetimes are added into evaporating droplets that contain nanoparticles with different types, sizes, concentrations, shapes, and wettability.
