Optimization of the digestion process of Scenedesmus sp. and Opuntia maxima for biogas production

Algaculture integration in conventional wastewater treatment plants: Anaerobic digestion comparison of primary and secondary sludge with microalgae biomass

“…When taking a closer look to which co-substrate is contributing to enhance the methane yields, most of the times microalgae is not the main contributor. In this manner, in addition to the study of Park and Li (2012) where the synergy was attributed to the lipid fraction, Ramos-Suárez et al (2014) reached the same conclusion. In this later study, the follow up of nitrogen mineralization evidenced low microalgae biodegradability and highlighted the need of pretreating microalgae biomass prior anaerobic codigestion.…”

“…This is the case of the mixture Scenedesmus sp. and Opuntia maxima (Ramos-Suárez et al, 2014). Out of several combinations, those authors reported that the feedstock composed of 75% O. maxima and 25% Scenedesmus sp.…”

“…The importance to study nitrogen mineralization was highlighted by Ramos-Suárez et al (2014), since codigestion of substrates may result in misleading conclusions. Furthermore, given the high content of proteins of activated sludge and microalgae biomass (Table 1), special attention should be given to the degradation of this macromolecule.…”

Enhancement of anaerobic batch digestion of spineless cacti (Opuntia ficus indica) feedstock by aerobic pre-treatment

“…There is an increasingly interest in evaluating the potential of O. ficus indica as feedstock for anaerobic digestion and biogas production (Jigar et al, 2011;Egigu, 2014;Calabr et al, 2017;Ramos-Suarez et al, 2014;Yang et al, 2015). Nevertheless, limited studies have dealt with pretreatment of the plant cladodes prior to anaerobic digestion and the effect they could have on both methane production and yield.…”

An integrated approach for biodiesel and bioethanol production from Scenedesmus bijugatus cultivated in a vertical tubular photobioreactor

“…Among the renewable biomass resources, microalgal biomass is rapidly emerging as a promising third generation feedstock for the production of biofuels such as biodiesel and bioethanol [5][6][7]. Microalgal biomass are environmentally sustainable [8,9], because they do not compete with other food crops for arable land and water [10,11]. Compared to first and second generation biofuel feedstocks, algae can produce more energy per hectare [12].…”
