Reproductive sterility increases the capacity to exploit the green seaweed Ulva rigida for commercial applications

摘要: Abstract Periodic biomass losses caused by reproduction have greatly limited the expansion of land-based cultivation seaweed Ulva. In an attempt to resolve this, we obtained a sterile mutant (SM) U. rigida mutating wild type (WT) strain using ultraviolet radiation (UVC). The SM grew five times faster than WT with 40.0% and 30.9% higher nitrate phosphate uptake rates. Crucially, remained in vegetative state throughout 27-day trial, unlike WT. lipid content was more double that monounsaturated, polyunsaturated, omega-3 omega-6 fatty acids but 26.3% lower protein content. swelling, water holding, oil holding capacities were all rapidly growing showed distinct promise for application carbon capture wastewater bioremediation conventional aquaculture practices. Despite some modified nutritional functional properties, still retained desirable profile.
