A novel native bioenergy green alga can stably grow on waste molasses under variable temperature conditions
Energy Conversion and Management(2019)
摘要
In the present work, a novel native bioenergy-producing green alga was isolated and purified from a local mountain. Photobiological H2 and lipid metabolism analyses indicated that this alga could serve as a candidate for renewable bioenergy resource. The strain was then defined as Coelastrum sp. strain XNY8011 though morphological and molecular characterization. The significant adaptability to wide range of temperatures for organic waste utilization of this strain is of great interest to the authors. When grew in 0.2% (w/v) molasses at low temperature like 15 °C, Coelastrum sp. strain XNY8011 produced 13.5 folds and 4.2 folds of cell biomass and chlorophylls respectively compared to the model strain Chlamydomonas reinhardtii CC503. Biomass and photosynthetic pigments productivities with temperature resistance strongly suggested this native isolated strain is one of the desired species to develop cost-saving biomass and bioenergy production at large scale.
