Potential and Prospects of Continuous Polyhydroxyalkanoate (PHA) Production

open access: yesBioengineering, 2015
Together with other so-called “bio-plastics”, Polyhydroxyalkanoates (PHAs) are expected to soon replace established polymers on the plastic market.

A new proof of the competitive exclusion principle in the chemostat

open access: yes, 2017
We give an new proof of the well-known competitive exclusion principle in the chemostat model with $n$ species competing for a single resource, for any set of increasing growth functions. The proof is constructed by induction on the number of the species,

Antibiotic residues and R-plasmid selection: are in vitro methods good models? [PDF]

open access: yes, 1987
Three clones of E. coli, one of which was harbouring a tetracycline resistance plasmid were inoculated together into the stomach of axenic mice. Without antibiotic selective pressure, the R-Plasmid bearing strain became dominant in the faeces of mice ...

Complex Dynamics in a Tritrophic Chain Model With Prey Stage Structure

open access: yesJournal of Applied Mathematics, Volume 2026, Issue 1, 2026.
A tritrophic chain model with prey stage structure (reproductive and nonreproductive classes) is analyzed. This model is provided by an ODE system of dimension four and the main premise consists in assuming that the interaction between reproductive population and predator is governed either by a functional response Holling type II or IV (where a ...

The Effect of Pellicle on Biofilm Formation in a Supragingival Biofilm Model

open access: yesClinical and Experimental Dental Research, Volume 11, Issue 6, December 2025.
ABSTRACT Objectives Oral biofilms initiate with the formation of an acquired pellicle on dental surfaces, a thin layer of salivary glycoproteins that provides a substrate for microbial adhesion. This study aimed to assess the necessity of a preformed pellicle for biofilm growth in vitro by analyzing the development of a standardized six‐species biofilm,

Hybrid Modeling for Bioprocesses: Architectures, Applications, and Perspectives

open access: yesEngineering Reports, Volume 7, Issue 12, December 2025.
This review analyzes 270 studies on hybrid semi‐parametric modeling in bioprocess engineering, highlighting dominant architectures, applications, and tools. It emphasizes the potential of hybrid models and process‐systems engineering to improve accuracy, extrapolation, and sustainability, aligning bioprocess development with key UN Sustainable ...

High-pressure continuous culturing: life at the extreme

open access: yesApplied and Environmental Microbiology
Microorganisms adapted to high hydrostatic pressures at depth in the oceans and within the subsurface of Earth’s crust represent a phylogenetically diverse community thriving under extreme pressure, temperature, and nutrient availability conditions.

An Effective Method of Continuous Production of Erythritol from Glycerol by Yarrowia lipolytica MK1

open access: yesFood 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.
