Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industrial use of microalgae is limited to a few species like Chlorella, Euglena, and Spirulina, which are not adaptable to outdoor cultivation and do not meet the requirements of high density growth and environmental resilience, and there is a lack of diverse microalgae strains suitable for industrial applications.
Innovation Solution
The development of novel microalgae strains from the Cyanidiophyceae family, including haploid and diploid forms, which are resistant to environmental changes and can be cultured outdoors, and methods for producing nutrient-rich compositions from these microalgae.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If microalgae are used for industrial cultivation, then productivity and economic value are improved, but the variety of usable species is limited to only a few types
Solution Approach 1:
The patent applies parameter changes by inducing haploid cells from diploid microalgae through controlled environmental conditions (temperature shock, pH changes, nutrient deprivation). This transformation changes the genetic parameter of the algae, enabling them to develop rigid cell walls and survive in outdoor environments, thereby expanding the range of industrially cultivable species while maintaining high productivity
2Productivity
If microalgae are cultured outdoors in large quantities, then productivity is improved, but the algae must meet strict requirements for environmental resistance and high-density growth
Solution Approach 1:
The patent transforms diploid microalgae into haploid forms through environmental parameter changes (temperature, pH, nutrient conditions). This genetic transformation enables the algae to develop rigid cell walls and acquire resistance to environmental stresses, allowing them to meet the reliability requirements for outdoor cultivation while maintaining high productivity
3Adaptability or versatility
If haploid microalgae are produced from diploid cells, then new strains with desired properties are obtained, but the process requires specific induction conditions and time
Solution Approach 1:
The patent applies preliminary action by pre-treating diploid microalgae with specific environmental conditions (nutrient deprivation, temperature stress, pH adjustment) before the actual haploid induction occurs. This preliminary preparation accelerates the induction process and increases the efficiency of haploid cell generation, reducing the overall time required while maintaining strain diversity
