Diverse Microbial Communities Assemble on Both Recalcitrant and Labile Carbon Sources

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Taxonomically and functionally distinct communities assemble on cellulose and its monomer, glucose. Although single carbon sources were provided, high and comparable diversity was maintained in both environments, supported by extensive cross‐feeding and scavenging. However, glucose supported higher biomass than cellulose and selected generalists, while

Proteomic Analysis of Lactococcus lactis FM03 Under Prolonged Alkaline Stress

Environmental Microbiology, Volume 28, Issue 7, July 2026.
Overview of alkaline resistance mechanisms in Lactococcus lactis FM03. Sustained growth at pH 8 triggers extensive physiological remodelling, including activation of general stress response proteins, suppression of acid resistance, elevated amino acid production, altered cell wall biosynthesis, and doubling of the cell wall thickness.

Study of Light Wavelength Dependency in Red-Orange Spectrum on Continuous Culture of Synechocystis sp. PCC6803 [PDF]

Iranian Journal of Chemical Engineering, 2019
In this study, the effect of light wavelength on growth rate and lipid production of Synechocystis was investigated. Continuous cultivation system was used to have uniform cell density and avoid self-shading in order to obtain more precise results. Based

Dynamics of Nonautonomous Chemostat Models [PDF]

, 2015
Chemostat models have a long history in the biological sciences as well as in biomathematics. Hitherto most investigations have focused on autonomous systems, that is, with constant parameters, inputs and outputs. In many realistic situations these quantities can vary in time, either deterministically (e.g., periodically) or randomly. They are then non-

In Vivo Enzyme Catalytic Rates in Formate‐Growing Methanococcus maripaludis

Microbial Biotechnology, Volume 19, Issue 7, July 2026.
In vivo catalytic rates of Methanococcus maripaludis enzymes during C1 carbon source limited growth were determined from metabolic model estimated fluxes and proteomics data. They showed weak agreement with turnover numbers predicted from sequences.

Evolutionary Attractors in the Chemostat Model

SIAM Journal on Applied Mathematics
We consider the evolutive chemostat model with a continuous phenotypic trait of the micro-organisms that impacts both the specific growth rate and the yield conversion, and whose evolution is driven by a mutation kernel. We study the evolutionary attractors (EAs) for a general class of non-linear growth functions, without assuming that the dynamics of ...
