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.

Alternative solutions to chemical fertilizers that can enhance soil fertility, increase crop yield, promote sustainable agriculture and reduce harmful environmental impacts are urgently required. Microalgal bio-inoculants improve plant growth yet the response of native microbiome microalgal application remains largely unexplored. A pot experiment was conducted assess effects microalgae (a consortium cyanobacteria green microalgae) inoculation on yield chili plant, fertility microbiome. Our results showed significantly enhanced morphometric parameters increased dehydrogenase activity (p < 0.05). Similarly, organic carbon , chlorophyll total polysaccharides nutrients such as nitrogen phosphorus potassium manganese were also 0.05) enriched in treatment groups (50% 100%) compared control. Results microbial diversity, with richness being higher treated soils than Metagenomics analysis revealed a shift bacterial fungal community composition firmicutes, chloroflexi, planctomycetes, proteobacteria, bacillariophyta, basidiomycota glomeromycota dominating microalgal- soils, while actinobacteria, bacteroidetes, streptomycota control soils. The findings suggested bio-inoculation diversity microbiomes, growth, plants.

Abstract Microalgae’s adaptability and resilience to Earth’s diverse environments have evolved these photosynthetic microorganisms into a biotechnological source of industrially relevant physiological functions biometabolites. Despite this, microalgae-based industries only exploit handful species. This lack biodiversity hinders the expansion microalgal industry. Microalgal bioprospecting, searching for novel biological algal resources with new properties, remains low throughput time-consuming endeavour due inefficient workflows that rely on non-selective sampling, monoalgal culture status outdated, non-standardized characterization techniques. review will highlight importance bioprospecting critically explore commonly employed methodologies. We also current advances driving next generation smart focusing transdisciplinary methodologies potential enable high-throughput biodiscoveries.
