“…Some competitive advantages offered by camelina are its short growth cycle, low fertilizer input requirements for optimum grain production (Putnam, Budin, Field, & Breene, ), low water requirements relative to canola (Gao, Caldwell, & Jaing, ), its unique oil composition and properties (Berti, Gesch, Eynck, Anderson, & Cermak, ), its ability to thrive successfully on marginal lands (McKenzie, Smallfield, Fasi, & Martin, ), and therefore diminish competition for traditional agricultural farmlands needed for food and feed production (Chen, Bekkerman, Afshar, & Neill, ). First‐generation biofuel crops like corn, canola, and soybean are under scrutiny because of their direct competition for food and feed production (Mohr & Raman, ; Ziolkowska, ). Therefore, camelina, a crop not widely utilized for its food value, can minimize the negative impact on the food production chain (Yang, Caldwell, Corscadden, He, & Li, ) and may be deemed less controversial in the food versus fuel debate (Naik, Goud, Rout, & Dalai, ).…”

Sowing date and sowing method can have a profound influence on the productivity of alternative crops like camelina in semiarid agroecosystems. The objective of this study was to determine the effects of sowing date, sowing method, and cultivar on morphology, phenology, grain yield, oil concentration, oil, and biodiesel production of camelina. A 2‐year study was carried out at the University of Nevada, Reno Main Station Field Laboratory, during the spring to early summer of 2016 and 2017. Treatments were two sowing dates (SD) of 18 March 2016 (early SD) and 17 April 2016 (late SD) in Year 1 and 11 April 2017 (early SD) and 11 May 2017 (late SD) in Year 2. The change in SD in the second year was due to the excessively wet field condition preventing land preparation and sowing. There were two sowing methods (SM) imposed (broadcast and drill) and three cultivars of camelina (Blaine Creek, Columbia, and Pronghorn) arranged in a 3 × 2 × 2 factorial in a randomized complete block design experiment with four replications. Responses were considered different if p < 0.05. Grain yield of camelina was influenced by SD in Year 1 and SD × SM interaction in Year 2. In Year 1, grain yield was greater for early (921 kg/ha) compared to late SD (503 kg/ha, SE = 101). In Year 2, for early SD grain yield was not different between SM (average = 594 kg/ha), but for late, it was greater for drill (676 kg/ha) than broadcast (130 kg/ha, SE = 75). For broadcast SM, grain yield was greater for early (587 kg/ha) compared to late SD (130 kg/ha, SE = 75), but for drill SM, grain yield was not different between SD (average = 639 kg/ha). Oil concentration was affected by SD in both years, and in Year 1, for example, it was greater for early (295 g/kg) versus late SD (284 g/kg SE = 2.7). Both oil and biodiesel production followed a similar pattern to grain yield in this study. Based on the magnitude of differences observed in both years of this study, late SD and broadcast sowing are not viable options for farmers who want to venture into camelina production in Nevada.

“…They can easily capture CO 2 gas and convert it to high value by‐products like carbohydrates, lipids, and vitamins , . Although, the cultivation of microalgae is not economically feasible, partly as a result of temperature, photosynthesis, and significant growth and harvesting costs , the multitude of research reports that, in comparison to alternative feedstocks, microalgae have great potential for biofuel production , . Microalgae have higher growth rates and biomass productivity compare to agricultural crops and land plants.…”

Macro and Micro Algae in Pollution Control and Biofuel Production – A Review

Microalgae are biological sources with an extensive range of biotechnological applications, e.g., for bioremediation of industrial and municipal wastes. Microalgae are used to monitor environmental toxicants like pesticides, heavy metals, and pharmaceuticals and in the final stage of wastewater treatment when organic pollution should be removed. CO 2 capturing is also important due to the environmental issues. Macro/microalgae cultures, depending on their growth stages and life cycles, have great poten-tial for CO 2 fixation. They are a dominant group of microorganisms for biological treatments with regards to their substantial biosorption ability to deactivate toxic heavy metals. Actual carbon biofixation can be employed in the direction of environmental sustainability and economic facility. Besides, algae are sustainable feedstock to produce a wide range of biofuels by applying thermochemical or biological conversion methods.

“…Crystalline cellulose is the largest component of lignocellulosic biomass—the most abundant form of biomass on earth. Its direct catalytic hydrolysis to glucose has been historically recognized as a central bottleneck in the transformation of biomass into value‐added fuels and chemicals 1–3. There is great interest in the development of solid synthetic catalysts that depolymerize crystalline cellulose through solid–solid interactions 4–11.…”

The direct hydrolysis of crystalline cellulose to glucose in water without prior pretreatment enables the transformation of biomass into fuels and chemicals. To understand which features of a solid catalyst are most important for this transformation, the nanoporous carbon material MSC‐30 was post‐synthetically functionalized by oxidation. The most active catalyst depolymerized crystalline cellulose without prior pretreatment in water, providing glucose in an unprecedented 70 % yield. In comparison, virtually no reaction was observed with MSC‐30, even when the reaction was conducted in aqueous solution at pH 2. As no direct correlations between the activity of this solid–solid reaction and internal‐site characteristics, such as the β‐glu adsorption capacity and the rate of catalytic hydrolysis of adsorbed β‐glu strands, were observed, contacts of the external surface with the cellulose crystal are thought to be key for the overall efficiency.
