“…and one actinobacterium Kocuria sp.) and two cyanobacteria (Anabaena laxa and Calothrix elenkinii) as plant growth promoting (PGP) agents was evaluated with seed spicescoriander, cumin and fennel, under controlled conditions in potting mix fortified with microbial cultures (Kumar et al, 2013a). Application of mycorrhiza associated bacteria like Pseudomonas putida with Glomus mosseae significantly increased the mycorrhizal colonization and growth of sapota and helped in establishment of healthy seedlings which has a large impact on establishment of seedlings and germplasm maintenance (Panneerselvam 2013).…”

The research efforts in microbiology over last two decades have focussed on assessing the microbial diversity in various soil types and cropping systems in all agro-eco-regions, including extreme environments resulting in creation of a vast repository of microorganisms, free living and endophytes. A marked departure from the past is their identification by both conventional and molecular methods, resulting in discovery of many novel species. The effects of various soil and agronomic management practices were assessed on soil microbial diversity and soil health by both classical and metagenomic approach. The beneficial effects of organic and integrated farming, and adverse effects of chemical intensification have been assessed, leading to the identification of actinobacteria as important players in maintaining soil health. A major impact has been the firm attention received from policy makers on the urgent need to conserve soil biodiversity and improve soil health. Identification of rapid methods of soil biological health assessment, improved rhizobial inoculants, microbial technology for rapid in situ and ex situ residue and waste breakdown, and mitigating climate change effects are the current priorities. Future priorities include assessment of the structure and function of the vast reservoir of unculturable microbes; deleterious microorganisms, assessment of soil-plant-microbe continuum and plant immunity modulation by microbes; rhizosphere engineering, role of archaea in maintaining soil health, microbial methods to improve soil organic matter formation; assessment and quantification of ecosystem services rendered by agriculturally important microorganisms; and improved microbial technology for biofertilizers and delivery systems. The tremendous advances in agricultural microbiology in last two decades in India are a cause for optimism that solutions will be forged for the above challenges using both classical and modern approaches, thereby ushering in the process more sustainable agricultural systems.

“…VICCRI via root-drench application showed greater plant height, leaf length, and grain yield than inorganic fertilizer ( Singh and Datta, 2007 ; Innok et al, 2009 ). Inoculation with A. laxa and Calothrix elenkinii increased the germination of coriander seeds and promoted root and shoot growth in coriander, cumin, and fennel ( Kumar et al, 2013 ). Soaking of seeds in a solution of Spirulina platensis (2 × 10 4 cells/ml) increased the fresh and dry weight, height, and root length of crop plants, including rocket, Bayam red, and Pak choi, by 1.2–3-fold compared with the untreated control ( Wuang et al, 2016 ).…”

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.

“…The use of green microalgae/cyanobacteria as biofertiliser can increase the activity of defence mechanism of the plants and improve their immunity by increasing the plant RNA activity, producing nutrient assimilating enzymes; dehydrogenase, nitrate reductase, acid or alkaline phosphatase, generating antioxidant and plants defence enzymes such as peroxidase, polyphenol oxidase, phenylalanine ammonia lyase and β-1, 3-endoglucanase in root and shoot of the plants [259,269,270]. Different strains of microalgae might provide different levels of defence mechanisms as shown by a study by Babu et al [271].…”

Microalgae are known as a rich source of bioactive compounds which exhibit different biological activities. Increased demand for sustainable biomass for production of important bioactive components with various potential especially therapeutic applications has resulted in noticeable interest in algae. Utilization of microalgae in multiple scopes has been growing in various industries ranging from harnessing renewable energy to exploitation of high-value products. The focuses of this review are on the isolation of bioactive compounds from microalgae regarding different metabolites which are currently used and new possible applications of the compounds in industries and future prospects. Moreover, this work discusses the advantage, potential new beneficial strains, applications, limitations, research gaps and future prospect of microalgae in industry.
