Summary
Algicidal bacteria offer sustainable solutions for controlling harmful algal blooms (HABs) and improving microalgal biomass processing. These bacteria demonstrate significant potential in managing aquatic ecosystems and developing eco-friendly biotechnologies.
Area of Science:
- Microbiology and Aquatic Ecology
- Biotechnology and Environmental Science
Background:
- Algae-bacteria interactions are crucial for aquatic ecosystem dynamics, influencing nutrient cycling and species succession.
- Harmful algal blooms (HABs) and inefficient algal biomass processing pose significant environmental and economic challenges.
Purpose of the Study:
- To review the diverse interaction modes between bacteria and microalgae.
- To analyze the biotechnological applications of algicidal bacteria for HAB control and biomass processing.
Main Methods:
- Literature review of algae-bacteria interactions, focusing on algicidal bacteria.
- Analysis of mechanisms, environmental factors, and implications of these interactions.
- Evaluation of algicidal bacteria in HAB control, bioflocculation, and biomass pretreatment.
Main Results:
- Algicidal bacteria effectively inhibit HAB species like *Microcystis aeruginosa* (24.87%-98.8% efficiency).
- These bacteria play roles in bioflocculation and microalgal biomass pretreatment.
- Identified constraints and challenges in biotechnological applications.
Conclusions:
- Strategic use of algicidal bacteria is vital for aquatic environmental health and efficient biomass processing.
- Future research should focus on scalability for both in situ and industrial applications.
