“…Intriguingly, changes in microbiota community structure by application of CHK0059 were detected in the crown endosphere, but not in the rhizosphere, regardless of the strawberry cultivars. The results support a previous finding that the application Chlorella vulgaris did not affect bacterial diversity in the bean rhizosphere [ 20 ]. Unfortunately, no analysis of the endosphere microbiota community of beans was attempted due to the influence of microalgae in the study [ 20 ].…”

Microalgae are photosynthetic cyanobacteria and eukaryotic microorganisms, mainly living in the water. In agriculture, numerous studies have been conducted to utilize microalgae as a biostimulant resource. Scenedesmus has been known to be one such microalga that can promote plant growth by secretion of auxin or cytokinin hormone analogs. However, no research has been performed on the effect of microalgae treatment on plant microbiota communities. This study was conducted to investigate the mode of action of microalgae as biostimulants in a plant microbiota perspective by using Scenedesmus sp. CHK0059 (also known as species Chlorella fusca ), which has been well documented as a biostimulant for strawberries. The strawberry cultivar Keumsil was bred with Seolhyang and Maehyang as the parent cultivars. Using these three cultivars, microbiota communities were evaluated for changes in structural composition according to the CHK0059 treatment. CHK0059-treated Seolhyang, and CHK0059-untreated Maehyang were similar in microbial diversity in the endosphere. From a microbiota community perspective, the diversity change showed that CHK0059 was affected by the characteristics of the host. Conversely, when CHK0059 treatment was applied, populations of Streptomyces and Actinospica were observed in the crown endosphere.

“…Although it is considered that N 2 -fixation is only carried out by prokaryotic organisms like cyanobacteria, Clostridium, and Bacillus among others, this process can also be promoted by the addition of eukaryotic microalgae. It was shown that the application of the biomass of Chlorella vulgaris IPPAS C-1 with a sprinkler into bean crops showed an increased in the fixation of bioavailable nitrogen in the soil below the plant [ 7 , 71 ], making the use of microalgae as a natural source of N for the plants appealing.…”

Due to the constant growth of the human population and anthropological activity, it has become necessary to use sustainable and affordable technologies that satisfy the current and future demand for agricultural products. Since the nutrients available to plants in the soil are limited and the need to increase the yields of the crops is desirable, the use of chemical (inorganic or NPK) fertilizers has been widespread over the last decades, causing a nutrient shortage due to their misuse and exploitation, and because of the uncontrolled use of these products, there has been a latent environmental and health problem globally. For this reason, green biotechnology based on the use of microalgae biomass is proposed as a sustainable alternative for development and use as soil improvers for crop cultivation and phytoremediation. This review explores the long-term risks of using chemical fertilizers for both human health (cancer and hypoxia) and the environment (eutrophication and erosion), as well as the potential of microalgae biomass to substitute current fertilizer using different treatments on the biomass and their application methods for the implementation on the soil; additionally, the biomass can be a source of carbon mitigation and wastewater treatment in agro-industrial processes.

“…In the line of this study, more direct approaches were also attempted. Next-generation sequencing of 16S rRNA amplicons was conducted to determine the effect of C. vulgaris application on bean root microbiota ( Kublanovskaya et al, 2019 ). Interestingly, no significant changes were detected in bacterial diversity in the bean rhizosphere upon the application of C. vulgaris .…”

Previously, algae were recognized as small prokaryotic and eukaryotic organisms found only in aquatic habitats. However, according to a recent paradigm shift, algae are considered ubiquitous organisms, occurring in plant tissues as well as in soil. Accumulating evidence suggests that algae represent a member of the plant microbiome. New results indicate that plants respond to algae and activate related downstream signaling pathways. Application of algae has beneficial effects on plant health, such as plant growth promotion and disease control. Although accumulating evidence suggests that secreted compounds and cell wall components of algae induce physiological and structural changes in plants that protect against biotic and abiotic stresses, knowledge of the underlying mechanisms and algal determinants is limited. In this review, we discuss recent studies on this topic, and highlight the bioprotectant and biostimulant roles of algae as a new member of the plant beneficial microbiome for crop improvement.
