Unlocking 3D printing technology for microalgal production and application.

Microalgae offer a promising alternative for sustainable nutritional supplements and functional food ingredients and hold potential to meet the growing demand for nutritious and eco-friendly food alternatives. With the escalating impacts of global climate change and increasing human activities, microalgal production must be enhanced by reducing freshwater and land use and minimizing carbon emissions. The advent of 3D printing offers novel opportunities for optimizing microalgae production, though it faces challenges such as high production costs and scalability concerns.

Enhancing astaxanthin production from Chromochloris zofingiensis via blue light and exogenous inducers in plate photobioreactors.

This study investigates the photoinduction techniques for the maximization of astaxanthin production in Chromochloris zofingiensis following heterotrophic growth. Leveraging blue light, this study enhanced carbon allocation by suppressing the tricarboxylic acid cycle and activating the methylerythritol phosphate and pentose phosphate pathways to facilitate astaxanthin accumulation. Under blue light, an astaxanthin content of 5.

Heterologous expression of a recombinant ACE inhibitory peptide LYPVK and its potential antihypertensive action mechanism.

Enzymatic hydrolysis approach is commonly employed for preparation of active peptides, while the limited purity and yield of produced peptides hinder further development of action mechanisms. This study presents the biotechnological approach for the efficient production of recombinant angiotensin converting enzyme (ACE) inhibitory peptide LYPVK and investigates its potential antihypertensive action mechanism. DNA encoding sequence of recombinant peptide was designed to form in tandem, which was expressed in Escherichia coli BL21 (DE3).

Construction of a High-Density Genetic Linkage Map and QTL Mapping for Stem Rot Resistance in Passion Fruit ( Sims).

Background: The passion fruit ( Sims) is a diploid plant (2n = 2x = 18) and is a perennial scrambling vine in Southern China. However, the occurrence and spread of stem rot in passion fruit severely impact its yield and quality.

Methods: In this study, we re-sequenced a BCF population consisting of 158 individuals using whole-genome resequencing.

A Microfluidic Biosensor for Quantitative Detection of in Traditional Chinese Medicine.

Microbial contamination is an important factor threatening the safety of Chinese medicine preparations, and microfluidic detection methods have demonstrated excellent advantages in the application of rapid bacterial detection. In our study, a novel optical biosensor was developed for the rapid and sensitive detection of in traditional Chinese medicine on a microfluidic chip. Immune gold@platinum nanocatalysts (Au@PtNCs) were utilized for specific bacterial labeling, while magnetic nano-beads (MNBs) with a novel high-gradient magnetic field were employed for the specific capture of bacteria.
