A pathway to improve seaweed aquaculture through microbiota manipulation

Area of Science:

• Marine microbiology
• Aquaculture science
• Eukaryotic host-microbiota interactions

Background:

• Eukaryotic hosts rely on associated microbial communities for essential functions.
• Beneficial microorganisms, such as probiotics and plant growth-promoting microorganisms (PGPMs), enhance host health and performance.
• Seaweed beneficial microorganisms (SBMs) are emerging as key players in seaweed development and disease resistance.

Purpose of the Study:

• To outline a strategy for enhancing commercial seaweed cultivation via microbiota manipulation.
• To emphasize the importance of understanding SBMs for seaweed aquaculture and restoration.
• To discuss challenges and opportunities in identifying and applying SBMs in seaweed farming.

Main Methods:

• Literature review and synthesis of current knowledge on SBMs.
• Analysis of existing and potential approaches for SBM identification and application.
• Discussion of microbiota manipulation strategies in the context of seaweed aquaculture.

Main Results:

• SBMs demonstrate potential to improve seaweed growth and disease resistance.
• Microbiota manipulation presents a viable pathway for advancing seaweed aquaculture.
• Further research into SBMs' modes of action is crucial for optimizing their application.

Conclusions:

• Harnessing SBMs can significantly benefit seaweed aquaculture and restoration efforts.
• A deeper understanding of SBMs is essential for unlocking their full potential in marine ecosystems.
• Strategic application of SBMs offers a promising avenue for sustainable seaweed farming expansion.
