Abstract Background Hydrogen photoproduction from green microalgae is regarded as a promising alternative solution for energy problems. However. the simultaneous oxygen evolution from microalgae can prevent continuous hydrogen production due to the hypersensitivity of hydrogenases to oxygen. Sulfur deprivation can extend the duration of algal hydrogen production. https://echobookmarks.com/story19493413/sovereign-cds-premiums-reaction-to-macroeconomic-news-an-empirical-investigation
