Quantitative Criterion to Predict Cell Adhesion by Identifying Dominant Interaction between Microorganisms and
This study introduces a new way to predict how cells stick to surfaces. The method compares two types of interactions: acid-base and electrostatic. By measuring specific properties of the microorganism and the surface, the model can determine which interaction is stronger. When acid-base interactions dominate, cell adhesion decreases with a specific formula. When electrostatic interactions dominate, adhesion decreases with another formula. The model was tested on microalgae, bacteria, and fungi, and it correctly predicted adhesion behavior. This approach could help in designing surfaces that either promote or prevent cell adhesion in various applications.
Area of Science:
- Microbial adhesion in biotechnology
- Surface interaction modeling in materials science
- Colloidal stability in environmental engineering
Background:
Cell adhesion is a widespread phenomenon with relevance in biotechnology, materials science, and environmental engineering. Prior research has shown that adhesion involves complex interactions between microorganisms and surfaces. However, no prior work had resolved how to distinguish between dominant interaction types in a quantitative way. Established knowledge includes the roles of electrostatic and acid-base forces, but uncertainty remained about how to predict which interaction dominates in specific cases. This gap motivated the need for a predictive model that integrates both types of interactions. No prior work had resolved how to combine electron-donor characteristics with ζ potentials in a unified framework. That uncertainty drove the development of a new quantitative criterion. This gap motivated the need for a predictive model that integrates both types of interactions.

Purpose Of The Study:
The aim of this study was to develop a quantitative criterion to predict cell adhesion by identifying the dominant interaction type. The specific problem addressed is the lack of a unified model to distinguish between acid-base and electrostatic interactions in microbial adhesion. The motivation comes from the need to improve predictions in biotechnology and materials science applications. The researchers propose a framework based on electron-donor characteristics and ζ potentials. This approach allows for the comparison of acid-base and electrostatic interactions in a single model.

This approach allows for the comparison of acid-base and electrostatic interactions in a single model.
Main Methods:
The study used a theoretical framework combining electron-donor characteristics and ζ potentials. The researchers compared two expressions involving γmv-, γsv-, ζm, and ζs. Experimental validation was performed using microalgae, bacteria, and fungi on various surfaces. Data from literature studies were also incorporated for verification. The dominant interaction was determined by comparing the two expressions. The model was tested across multiple microorganism-surface combinations. Data from literature studies were also incorporated for verification. The dominant interaction was determined by comparing the two expressions.
Main Results:
The results showed that adhesion behavior depends on the dominant interaction type. When acid-base interactions were dominant, adhesion decreased with increasing [Formula: see text]. When electrostatic interactions were dominant, adhesion decreased with increasing (ζm + ζs)2. The model was validated using microalgae, bacteria, and fungi. Experimental data confirmed the predicted trends. The criterion was tested on surfaces with varying electron-donor characteristics. The model successfully distinguished between acid-base and electrostatic dominance. The criterion was tested on surfaces with varying electron-donor characteristics.
