Cyanobacteria are well known for their biofertilizing capacities, which can enhance soil fertility and plant growth. This study aims to evaluate the effects of indigenous nitrogen-fixing cyanobacterium Anabaena cylindrica on growth, biochemical, physiological responses wheat, as fertility. Medium filtrate, aqueous extract, sonicated culture, crude culture A. at different doses (50%, 25%, 1%, 0.2% v/v) were applied using a drench under greenhouse conditions. After 40 days all cyanobacterial suspensions significantly increased wheat biochemical properties, mineral composition compared controls. The greatest improvements observed with application highest concentrations, 25% 50%. These also enhanced nutritional physicochemical properties soil. Among treatments, inoculation (living cells) growth medium filtrate 50% most efficient. growth–promoting effect was attributed intracellular or released bioactive compounds cylindrica, such polysaccharides, proteins, indole acetic acid phytohormone, nitrogen, phosphorus, potassium. demonstrates that terrestrial cylindrica-derived promote be used an effective eco-friendly biofertilizer crop productivity.

This study aimed to evaluate the impact of a more cost-efficient strigolactone mimic SL-6 on Chlorella sorokiniana NIVA-CHL 176 growth in comparison with analog GR24 and plant biostimulant functions microalgal extracts. Three molar concentrations were tested: 10-7 M, 10-8 10-9 respectively. Five parameters assessed: optical density, turbidity, biomass production, chlorophyll fluorescence, pigment concentration. Results after 15 days culturing revealed that treatments significantly enhanced production (13.53% at M), synthesis, photosystem II activity (14.38% M). The highest increases pigments induced by 15.7% for (at M SL-6), 12.87% b 2.3% carotenoids 10.78% total SL-6) per gram compared solvent control (DMSO).

Physiological Effects and Mechanisms of Chlorella vulgaris as a Biostimulant on the Growth and Drought Tolerance of Arabidopsis thaliana

Plants, Journal Year: 2024, Volume and Issue: 13(21), P. 3012 - 3012

Published: Oct. 28, 2024

Microalgae have demonstrated biostimulant potential owing to their ability produce various plant growth-promoting substances, such as amino acids, phytohormones, polysaccharides, and vitamins. Most previous studies primarily focused on the effects of microalgal biostimulants growth. While biomass extracts are commonly used biostimulants, research use culture supernatant, a byproduct culture, is scarce. In this study, we aimed evaluate Chlorella vulgaris assess its growth drought tolerance Arabidopsis thaliana, addressing gap in current knowledge. Our results that cell-free supernatant (CFS) significantly enhanced root shoot development both seedlings mature plants, suggesting presence specific compounds CFS. Notably, CFS appeared improve plants by increasing glucosinolate biosynthesis, inducing stomatal closure, reducing water loss. Gene expression analysis revealed considerable changes drought-responsive genes, IAA5, which involved auxin signaling, well biosynthetic including WRKY63, MYB28, MYB29. Overall, C. culture-derived could serve alternative chemical products, enhancing tolerance.

Effects of Microalgae as Biostimulants on Plant Growth, Content of Antioxidant Molecules and Total Antioxidant Capacity in Chenopodium quinoa Exposed to Salt Stress

Plants, Journal Year: 2025, Volume and Issue: 14(5), P. 781 - 781

Published: March 4, 2025

Chenopodium quinoa Willd. is a halophytic plant valued for its nutritional and nutraceutical properties, as well adaptability to diverse soil climatic conditions. Biostimulant application enhances quality resilience under adverse environmental The effects of microalgae extracts (Ettlia pseudoalveolaris Chlorella vulgaris) salt stress (NaCl 100, 200, 300 mM) were evaluated on 7-day-old seedlings two varieties, ‘Tunkahuan’ ‘Regalona’. analysis focused the content antioxidant molecules (total phenolics flavonoids), total capacity (measured by DPPH, 2,2-Diphenyl-1-picrylhydrazyl, FRAP, Ferric Reducing Antioxidant Power, assays), reactive oxygen species (ROS), levels lutein, β-carotene, chlorophyll b. Microalgae treatments significantly increased in both varieties. highest activity, measured DPPH assay, was observed ‘Regalona’, while dose-dependent increase capacity, FRAP evident treated with Ettlia. ROS level reduced Ettlia but not Pigment higher concentrations decreased addition biostimulants. These findings suggest that bioactive compounds, improving salinity resistance increasing value sprouts.

Biofertilizers derived from microalgae are increasingly used as promising materials for improving crop growth and development, producing fewer catastrophic environmental effects. Hence, the large-scale production of eco-friendly broad-spectrum biofertilizers is mandatory. Therefore, this study was designed to examine potential efficacy isolated algae strains, such Spirulina platensis, maxima, Chlorella vulgaris, improve development Pak Choi.
