Mixotrophy of Algae: More Algal Biomass and More Biofertilization for Plants

Background: The use of algae as biofertilizers is fast-spreading in order to meet the excessive demands for agricultural products. To achieve this, enough algal biomass needs be supplied year-round. Hence, nutritional components must optimized through mixotrophic conditions. Materials and methods: Two isolates, namely, Phormidium sp. Synechocystis were tested their ability produce growth using different supplementations including molasses, aqueous Lepidium sativum, Trigonella foenum graecum seed extract liquorice root extract, well acetate salt solution. that showed highest under conditions was further used cantaloupe experiments. GC-MS also carried out on one fractions solvent system reveal some dominant novel bioactive compounds biomass. Results: sugarcane molasses significantly enhanced two strains, followed by sativum only case Therefore, it subsequent All parameters addition these sources with being best supplement. rich its content chlorophyll, proteins, sugars revealed GC–MS. germination percentage seeds treated a significant increase over control. growth-related metabolites total soluble all photosynthetic pigment contents seedlings increased this treatment. Discussion: superior enhancing due not but minerals nitrogenous compounds. extracts more than control set are omega-3 fatty acids, phytochemicals other essential nutrients. In experiments seeds, there Conclusion: Mixotrophic achieved better production autotrophy cheap resources such which waste from sugar industry, common herb cost-effective approach. mixotrophically grown blue-green alga biofertilizer plant germination, indicating usefulness eco-friendly strategy achieving both food security environmental sustainability.
