Crop yield and quality improvements, building of resistance toward biotic and abiotic stresses and enhancing nutrient use efficiency are some of the demonstrated benefits of seaweed extracts when they applied on the crops.In the present study, a concentrated seaweed extract (CSW) was produced by a blend of red (Gracilaria salicornia) and brown seaweed (Sargassum swartzii) extracts and evaluated its biostimulant and salt mediated stress alleviating activities by using a green gram (Vigna radiata) seedling method.The CSW (soluble solids: 29.93 ± 0.84%) was tested to contain macro- and micronutrients, plant growth regulators (auxins, cytokinins, and gibberellic acid), amino acids, and alginic acids.The biostimulant activity was evaluated by growing the stem cuttings of green gram seedlings in different concentration of CSW for 10 days and roots developed were measured by a WinRhizo Pro root imaging system.The salt-mediated stress-alleviating activity of CSW was studied by growing the green gram stems in different concentration of sodium chloride, i.e., 25, 50, and 75 mM along with 0.1% of CSW and control experiment was run in parallel to compare the results.It was observed that CSW at 0.1% mitigated the salt stress up to a 50 mM concentration level and promoted the normal root growth and increased the plant biomass by 18.86% over the control (p = .01).The entire assay work, except pot trial, was completed in 21 days, hence it could a useful test method to assess the biostimulant and or salt mediated stress alleviating activities of biostimulants.

Phycoerythrin (PE) is a photosensitive red pigment from phycobiliprotein family predominantly present in the red algae. The concentration of PE depends on photon flux density (PFD) and the quality of light absorbed by the algae tissue. This necessitates robust techniques to extract PE from the embedded cell-wall matrix of the algal frond. Similarly, PE is sensitive to various factors which influence its stability and purity of PE. The PE is extracted from Red algae through different extraction techniques. This review explores an integrative approach of fractionating PE for the scaling-up process and commercialization. The mechanism for stabilizing PE pigment in food was critically evaluated for further retaining this pigment within the food system. The challenges and possibilities of employing efficient extraction for industrial adoption are meticulously estimated. The techniques involved in the sustainable way of extracting PE pigments improved at a laboratory scale in the past decade. Although, the complexity of industrial-scale biorefining was found to be a bottleneck. The extraction of PE using benign chemicals would be safe for food applications to promote health benefits. The precise selection of encapsulation technique with enhanced sensitivity and selectivity of the membrane would bring better stability of PE in the food matrix.
