ScanGrow: Deep Learning-Based Live Tracking of Bacterial Growth in Broth

open access: yesFrontiers in Microbiology, 2022
Monitoring the growth of bacterial cultures is one of the most common techniques in microbiology. This is usually achieved by using expensive and bulky spectrophotometric plate readers which periodically measure the optical density of bacterial cultures ...

Modeling of the Bacterial Growth Curve [PDF]

open access: yesApplied and Environmental Microbiology, 1990
Several sigmoidal functions (logistic, Gompertz, Richards, Schnute, and Stannard) were compared to describe a bacterial growth curve. They were compared statistically by using the model of Schnute, which is a comprehensive model, encompassing all other models.

Regulation of Iron Storage by CsrA Supports Exponential Growth of Escherichia coli

open access: yesmBio, 2019
The global regulatory protein CsrA coordinates gene expression in response to physiological cues reflecting cellular stress and nutrition. CsrA binding to the 5′ segments of mRNA targets affects their translation, RNA stability, and/or transcript ...

A Single Nucleotide Polymorphism Is Involved in Regulation of Growth and Spore Formation of Bacillus anthracis Pasteur II Strain

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Anthrax toxins and capsules, which are encoded by genes located on pXO1 and pXO2, respectively, are major virulence factors of Bacillus anthracis. Our previous studies demonstrated that exposure to high-temperatures is unable to abolish the pXO1 plasmid ...

Development and validation of a mathematical model for pseudomonads growth as a basis for predicting spoilage of fresh poultry breast and thigh fillets

open access: yesPoultry Science, 2022
: The growth of naturally contaminated pseudomonads on fresh breast and thigh poultry fillets during aerobic storage was studied and modeled as a function of temperature (0–30°C). A statistical comparison of the models for breast and thigh fillets showed
