Construction of an improved Aspergillus niger platform for enhanced glucoamylase secretion

Microbial Cell Factories, 2018
BackgroundThe lifestyle of filamentous fungi depends on the secretion of hydrolytic enzymes into the surrounding medium, which degrade polymeric substances into monomers that are then taken up to sustain metabolism.

A Microfluidic Multiplex Sorter for Strain Development

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A new multiplex method for high‐throughput screening of yeast strains based on glucoamylase production is presented. Droplets containing single mutant yeast cells are incubated for enzyme production. A sorting platform divides mutants by their high‐ and mid‐activity levels.

Integrated Flexible Zwitterionic Electrochemical Sensor Platform for Real‐Time Salivary Glucose Quantification

Advanced Sensor Research, EarlyView.
A flexible electrochemical sensor platform can enable continuous, real‐time monitoring of salivary glucose for applications confined to spaces such as the oral cavity. Surface modifications with Prussian blue, chitosan, and zwitterionic polymers enhance sensitivity, selectivity, and antiadherent performance.

The fungus Aspergillus niger consumes sugars in a sequential manner that is not mediated by the carbon catabolite repressor CreA

Scientific Reports, 2018
In nature, the fungus Aspergillus niger degrades plant biomass polysaccharides to monomeric sugars, transports them into its cells, and uses catabolic pathways to convert them into biochemical building blocks and energy. We show that when grown in liquid
