Morphological development of Aspergillus niger in submerged citric acid fermentation as a function of the spore inoculum level. Application of neural network and cluster analysis for characterization of mycelial morphology

open access: yes, 2006
Although the citric acid fermentation by Aspergillus niger is one of the most important industrial microbial processes and various aspects of the fermentation appear in a very large number of publications since the 1950s, the effect of the spore inoculum

IN4MER Biomaterial Ink: A Phosphorescent Biosensing Biomaterial Ink for Multiple Analytes (Glucose, Lactate, Oxygen) Measurements and Temperature Sensing Applications

open access: yesAdvanced Functional Materials, EarlyView.
Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

Application of hypoosmolar medium to fed-batch culture of hybridoma cells for improvement of culture longevity

open access: yes, 1999
Cell culture longevity in fed-batch culture of hybridomas is often limited by elevated medium osmolality caused by repeated nutrient feeding. Shotwise feeding of 10x Dulbeccos modified Eagles medium (DMEM) concentrates elevated the osmolality of medium ...
