 A Practical Introduction to Turbidostat-Based E. coli Cultivation
Precise growth control is critical for reproducible microbial processes. This technical note shows how the BioXplorer 100 operates as a turbidostat using real-time turbidity feedback to maintain stable, high-density E. coli cultures. A calibrated non-linear approach supports continuous cultivation, consistent physiology, and high-productivity bioprocess development.

| | | | |  Breast cancer remains a predominant global health challenge for women, with late-stage diagnosis being a key contributor to its high mortality. | | | | |  Researchers at Oregon Health & Science University have identified a type of enzyme with a complicated name - cell migration inducing and hyaluronan-binding protein, or CEMIP - is associated with disorders ranging from multiple sclerosis to stroke to neurodegenerative conditions like Alzheimer's disease. | | | | | __639050909708546447_multisizecolor_150_custom.jpg) By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of Wisconsin–Madison have created a new way to improve our understanding of the origins of life on Earth and possibly recognize signs of life elsewhere. | | | | |  By reconstructing a non-natural metabolic route in Escherichia coli, the researchers demonstrated that simple sugars can be biologically converted into lauryl glucoside through the coordinated production of its fatty alcohol precursor and a final glycosylation step. | | | | |  Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S. | | | | |  Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation cycle of the Sir2 enzyme, reveal researchers from Science Tokyo. | | | | |  The emergence of cancer drug resistance remains one of the most pressing problems in cancer care and there is a critical need to devise approaches to mitigate it. | |
