Anaerobic Digestion: Feedstock, Inoculum and Experimental Set-Up. In [1,2] we Anaerobic digestion of algal biomass produces a nutrient-rich digestate containing both nitrogen and phosphorus nutrients. Digestate nutrient values of 2940 mg/L ammonia-nitrogen, 390 mg/L of total phosphorous, and 320 mg/L of potassium have been reported by Collet et al. [1]. Algae that are grown in wastewater treatment lagoons could be an important substrate for biofuel production; however, the low C/N ratio of algae is not conducive to anaerobic digestion of algae with economically attractive methane production rates.
Anaerobic digestion of algae requires pretreatment of the biomass and/or codigestion with carbon-rich cosubstrates, as discussed in this chapter. In the absence of pretreatment, the methane yield is reduced apparently because of the recalcitrance of the algal cell wall.

Biogas from Algae via Anaerobic Digestion Abstract. Authors Algae, a photoautotroph which could convert sunlight energy to chemical energy, is a promising feedstock option for anaerobic digestion compared to other organic solid waste due to the high yields without any requiring of use of arable land and fresh water resource showing low threat on food market ( Rodriguez et al., 2015 ).
Anaerobic digestion is the process by which organic matter such as animal or food waste is broken down to produce biogas and biofertiliser. The conditioned algal biomass will then enter the anaerobic digestion section where it will be fermented for 4-6 weeks and subsequently attacked by suitably chosen enzymes which will convert the contained lipids and proteins into methane and CO2. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester. AbstractAnaerobic digestion (AD) of algae biomass has been investigated since long. As a renewable energy, methane can be used for combustion, electricity and transport, reducing dependence on fossil energy ( Novais et al., 2018 ). The conditioned algal biomass will then enter the anaerobic digestion section where it will be fermented for 4-6 weeks and subsequently attacked by suitably chosen enzymes which will

Algae use these nutrients to grow, and in the process, remove them from the digestate. Lake algae can be digested anaerobically to produce hydrogen (H2), but the efficiency of actual processes is limited. Typically, aerobic treatment is applied to treat low strength wastewater (COD <1000 mg/L) when the treatment requires the presence of oxygen.

In this study, raw CM and, subsequently, the anaerobically digested liquid leachate were used as feed for AD and the microalgae cultivation process, respectively. Anaerobic digestion (AD) consists of a series of actions by various groups of bacteria that convert organic materials into methane, carbon dioxide, and bacterial biomass ( Figure 1 ). One particular opportunity, which is the focus of this work, is value-adding to algae residue by using it as a feedstock for anaerobic (co-)digestion. Search: Microalgae Postdoc.

Anaerobic digestion of algal biomass could theoretically reduce costs associated with drying wet biomass before processing, but practical yields of biogas from digestion of many algae are substantially below the theoretical maximum. The anaerobic digestion of microalgae is a prospective environmentally feasible option for creating a renewable source of energy for industrial and domestic needs. Goal 2: Anaerobic digestate is rich in nutrients, especially nitrogen and phosphorus, which are major nutrient pollutants if released directly into the environment.
