Symbiotic microalgae and microbes: a new frontier in saline agriculture

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: April 22, 2025

With the growing human population worldwide, innovative agricultural development is needed to meet food security needs. However, this has inadvertently led problematic irrigation practices and overuse of agrochemicals. Such can exacerbate soil salinization, which prevents plant growth. As a progressively widespread escalating problem, salinization poses major threat global security. Compared with traditional use microalgae or microorganisms that act on growth, microalgae–microorganism symbiosis significant advantages in promoting Microalgae work together provide wide range nutrients required by plants, they exhibit nutrient complementarity, supports Here, potential microalgae–microbial for enhancing salt tolerance was investigated. Our review demonstrated metabolic complementarity between enhance tolerance. The diversity symbiotic system improve ecosystem stability resistance reduce incidence disease under stress. These systems produce bioactive substances (e.g., phytohormones) promote crop yield, structure increasing organic matter improving water storage capacity fertility. Exploiting synergistic effects beneficial biotechnological applications offer novel solutions saline agriculture mitigate deleterious salinity health yield. there are several implementation challenges, such as allelopathic interactions autotoxicity. To make microalgae–bacteria consortia economically viable applications, optimal strains species need be identified strategies employed obtain sufficient biomass cost-effective manner. By elucidating mechanisms, ecological stability, resource utilization systems, clarifies stress responses promotes shift saline–alkali from single bioremediation systematic engineering.

Applications of the Microalgae Chlamydomonas and Its Bacterial Consortia in Detoxification and Bioproduction

Life, Journal Year: 2024, Volume and Issue: 14(8), P. 940 - 940

Published: July 27, 2024

The wide metabolic diversity of microalgae, their fast growth rates, and low-cost production make these organisms highly promising resources for a variety biotechnological applications, addressing critical needs in industry, agriculture, medicine. use microalgae consortia with bacteria is proving valuable several areas biotechnology, including the treatment various types wastewater, biofertilizers, extraction products from biomass. monoculture microalga Chlamydomonas has been prominent research model many years extensively used study photosynthesis, sulphur phosphorus metabolism, nitrogen respiration, flagellar synthesis, among others. Recent increasingly recognised potential Chlamydomonas-bacteria as tool applications. detoxification wastewater using its bacterial offers significant sustainable reduction contaminants, while facilitating resource recovery valorisation microalgal biofertilizers can offer benefits, such increasing crop yields, protecting crops, maintaining soil fertility stability, contributing to CO2 mitigation, agricultural practises. Chlamydomonas-bacterial play an important role high-value products, particularly biofuels enhancement H2 production. This review aims provide comprehensive understanding identify current applications propose new development directions maximise potential.
