“…In 1992, Kim and Gee published a work in "Water Environmental Research" prospecting the relevant rule of biotechnology for the treatment of hazardous wastes (Kim & Gee, 1992). Approximately 30 years later, we know that bacteria can support the sustainable implementation of a circular economy by increasing the performances of wastewater treatments for water reuse (Choudri, Al-Awadhi, Charabi, & Al-Nasiri, 2020); controlling GHG emissions by the capture and/or sequestration of CO 2 or reducing its global pressures in the atmosphere (Koh & Shaw, 2018); producing hydrogen, biomethane and different forms of bioenergy (Sheehan et al, 2018); and introducing other amazing solutions with promising applications for global sustainability (Chang, DiGiovanni, & Mei, 2019).…”

“…The higher biogas output from the co-digestion of algal biomass and other organic feedstocks has been attributed to the synergistic effects related to optimization of the micronutrients needed for the optimal growth of anaerobic microbes [34]. It should be emphasized that the literature describes the efficiency of co-fermenting microalgae biomass with many organic substrates, including sewage sludge [35], Virginia mallow [36] and various types of waste and wastewater [37,38] as well as maize silage [39]. However, there are no reports on the possibility of anaerobic digestion of the feedstock composed of microalgae biomass and Miscanthus × giganteus silage.…”

Co-Fermentation of Microalgae Biomass and Miscanthus × giganteus Silage—Assessment of the Substrate, Biogas Production and Digestate Characteristics

The development of a sustainable bioenergy market is currently largely fueled by energy crops, whose ever-increasing production competes with the global food and feed supply. Consequently, non-food crops need to be considered as alternatives for energy biomass production. Such alternatives include microalgal biomass, as well as energy crops grown on non-agricultural land. The aim of the present study was to evaluate how co-digestion of microalgal biomass with giant miscanthus silage affects feedstock properties, the biogas production process, biogas yields, methane fractions and the digestate profile. Combining giant miscanthus silage with microbial biomass was found to produce better C/N ratios than using either substrate alone. The highest biogas and methane production rates—628.00 ± 20.05 cm3/gVS and 3045.56 ± 274.06 cm3 CH4/d—were obtained with 40% microalgae in the feedstock. In all variants, the bulk of the microbial community consisted of bacteria (EUB338) and archaea (ARC915).

The new renewable energy source, namely microalgae biomass, which is the third generation in its utilization derivative, has a lipid content productivity that has great potential to be used as raw material for biodiesel production. One species of microalgae, Nannochloropsis sp., is ideal for cultivation and has a higher photosynthetic efficiency than land plants. Methods to obtain microalgae oil from dry raw materials can be carried out from several processes, but the most effective and easy method is extraction with solvents using a Soxhlet device. The purpose of this study was to determine the optimal growth of Nannochloropsis sp microalgae cell density observations in the cultivation process and to see the percent yield of lipids from microalgae Nannochloropsis sp. through the extraction process with the Soxhlet method using n-hexane and ethanol solvents at a ratio of 1:1, 1:2, 1:3, 1:4 and 1:5. The optimal amount of cell density during the cultivation process has obtained an average of 32.206 x 104 cells/ml on day of 9th, and the optimal lipid yield was in the ratio of hexane: ethanol 1:1 with a value of 32.13%. These results show that the optimal conditions for yield can be obtained and also has the potential as a raw material biodiesel production
