The economic feasibility of the next-generation algal biofuels rely largely on the simultaneous production of high-value-added bioproducts (HVABs) in these photosynthetic cell factories. In this study, a newly isolated indigenous microalga belonging to the selenastraceae family Monoraphidium sp. (designated as CABeR41) has been isolated and characterized for its relevant biofuel precursors along with other HVABs, i.e., tocopherols. Our preliminary data sets demonstrate accumulation of higher amounts of lipids (266.6 mg g–1 dcw) along with antioxidant molecules, such as α- and δ-tocopherols (456 μg g–1 dcw and 974 μg g–1 dcw), simultaneously when subjected to nutrient deprivation. The total tocopherol content has been increased in nitrogen-deplete conditions to 1450.24 μg g–1 dcw from 638.2 μg g–1 dcw. In conclusion, bioprospecting of new isolates from natural habitats and fine-tuning of specific conditions without compromising growth has potential for developing into a sustainable industrial strain for concomitant production of biofuels and bioproducts.

营养缺乏促进了独特生育酚的产生，作为一种新的本土分离物 Monoraphidium sp. 的应激促进反应。

下一代藻类生物燃料的经济可行性很大程度上取决于在这些光合细胞工厂中同时生产高附加值生物产品 (HVAB)。在这项研究中，一种新分离的本土微藻属于 selenastraceae 家族 Monoraphidium sp。（指定为 CABeR41）已被分离并表征其相关的生物燃料前体以及其他 HVAB，即生育酚。我们的初步数据集表明，大量的脂质（266.6 mg g-1 dcw）以及抗氧化剂分子（例如 α- 和 δ-生育酚（456 μg g-1 dcw 和 974 μg g-1 dcw）同时在遭受营养缺乏。在贫氮条件下，总生育酚含量从 638.2 μg g-1 dcw 增加到 1450.24 μg g-1 dcw。综上所述，
