Anaerobic Digestion of Microalgal Biomass Acutodesmus dimorphus (Turpin) P. Tsarenko as a Substrate for Biogas Production

Abstract

It is only a matter of time for when fossil fuels will not be accessible at low cost, which is the major reason why it is obligatory for researchers to find an alternative feedstock to replace the currently stable position of fossil fuels in the world. The objective of this study was to review the potential of green microalgae Acutodesmus dimorphus (Turpin) P. Tsarenko, which can become the replacement for the commonly used raw materials for anaerobic digestion. Recent scientific focus has targeted the research of alternative renewable energy sources. Green microalgae are the alternative raw material for generating bioenergy due to high photosynthetic efficiency. Many modern solutions for cultivation systems of microalgae, maintenance, and harvesting techniques are currently under development all over the world. It is necessary to find the proper technology for algae cultivation and that will deal with all environmental and economic issues. The innovative process can provide the prerequisite scale for increasing commercial use of bioenergy from microalgae. The interim research results presented in this study show that microalgae are a suitable alternative material for biogas production in the method of anaerobic fermentation.

Anaerobic digestion of microalgal biomass for bioenergy production, removal of nutrients and microcystin: current status

“…The research has revealed elevated methane yield (0Á9143 m 3 kg À1 dry matters (DM)) in the AD of Acutodesmus dimorphus (Turpin) P. Tsarenko is an alternative resource due to their photosynthetic efficiency. In addition to the various potentials of AD, the digesters release CO 2 , which could cultivate microalgae (Głowacka et al 2018).…”

Practical and Theoretical Modeling of Anaerobic Digestion of <i>Sargassum</i> spp. in the Mexican Caribbean

“…The need to dispose of this biomass and wastewater treatment sludge on the Caribbean coast, provides the opportunity for its energy harnessing via AD. Furthermore, according to Głowacka et al [48] which at the same time can be used as a raw material in the AD process. Studies agree that the success of the marine algae fuel industry depends on the energy balance of the processes, and so evaluations are required that along with identifying the viability of the implementation, also enable the commercialization of the biofuels generated [22,33].…”

High-Rate Algae Pond Coupled with Polyester Fiber Strips for Organics and Nutrient Removal in a Cold Climate

“…High-rate algae ponds (HRAP) are an efficient and inexpensive technology for algae biomass production, and in which a large quantity of wastewater can be treated [3]. Algae growth is considerably influenced by climatic conditions, particularly temperature [4][5]. Low temperature restrains algae photosynthetic activities and reduces algae growth, resulting in low purification efficiency.…”
