Mathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 12102-12115, 30 July 2026.ABSTRACT We investigate some chemostat models incorporating wall growth, competition, random fluctuations on the dilution rate, and different consumption functions (Monod and Haldane). We analyze the asymptotic behavior of the solutions of the corresponding random differential systems to establish conditions on the model parameters under which the ...

An Effective Method of Continuous Production of Erythritol from Glycerol by Yarrowia lipolytica MK1
Food Technology and Biotechnology, 2017 This study demonstrates the potential applicability of the UV mutant Yarrowia lipolytica MK1 for the valorisation of glycerol and erythritol production in a chemostat culture.

On Geometry and Scale of a Stochastic Chemostat [PDF]
Communications in Statistics - Theory and Methods, 2013 A chemostat is a fixed volume bioreactor in which micro--organisms are grown in a continuously renewed liquid medium. We propose a stochastic model for the evolution of the concentrations in the single species and single substrate case. It is obtained as a diffusion approximation of a pure jump Markov process, whose increments are comparable in mean ...

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics
Advanced Science, Volume 13, Issue 37, 3 July 2026.This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

Chemostat dynamics reveals rapid evolution. [PDF]
, 2019 L−A+ (WY1335) cells growing exponentially in excess lysine were washed free of lysine and inoculated into the culturing vessel (triangles: inoculation at near steady-state density in the absence of lysine; circles: inoculation at 1/3 steady-state density

Thermodynamic Evaluation of Dual Substrate Growth
Biotechnology and Bioengineering, Volume 123, Issue 7, Page 1825-1835, July 2026.ABSTRACT Various C₁–C₂ compounds are increasingly available through electrochemical reduction of CO2. Although not always suitable as a sole substrate, these compounds can supplement a primary substrate like glucose to enhance microbial growth. Yet, the mechanisms underlying the effects of dual substrate consumption on growth rate and growth yield ...

Coexistence of poorer competitors for all available resources requires greater niche overlap
Ecosphere, Volume 17, Issue 7, July 2026.Abstract The need for niche differentiation among resource competitors to coexist is a universally accepted principle in ecology. However, this principle is derived from models with one or two resources or no resource dynamics at all. Graphical analysis of a consumer‐resource model including three resources shows that a consumer that is not the best ...

Dynamical analysis of chemostat models incorporating variable yield coefficient and substrate inhibition with recycling process [PDF]
, 2021 This research analyses chemostat models for microbial production. Chemostat is a tool that can be used for the continuous production of microbes under controlled conditions such as pH, temperature, light, and nutrients.
