Microalgal biofuels in China: The past, progress and prospects

“…Optimized one-step sulfuric acid saccharification improved ethanol levels and fermentation efficiency Wu et al, (2014) Biohydrogen Chlamydomonas reinhardtii Culture in advanced solid-state fermentation wastewater increased photosynthetic H 2 evolution Chen, Zhang, Li, et al (2014) C. pyrenoidosa Two novel systems for production of hydrogen by photosynthesis in green algae cells have been reported Ma et al (2011), Wei et al (2017Wei et al ( , 2020, Xiong et al (2015) Algae bloom in Taihu Lake Biomass waste from algal bloom in Taihu Lake was efficiently utilized for hydrogen production Arthrospira platensis Two-stage continuous fermentative hydrogen and methane co-production offered better performance than one-stage anaerobic co-digestion Ding et al (2018) Scenedesmus obliquus Piggery anaerobic digestate liquid could be used for biogas production Xu et al (2015) Blooming cyanobacteria Anaerobic digestion of blooming cyanobacteria generated biogas and reduced microcystin production Yuan et al (2011) the oleaginous model alga C. subellipsoidea using various techniques to manipulate N levels, including one-stage continuous N-sufficiency, N-deprivation, N-limitation (OCNL), and two-stage batch N-starvation, suggesting that OCNL could be used for algal lipid production on a commercial scale. A two-step regime was also developed to enhance lipid accumulation in oleaginous microalgae.…”

“…High levels of polysaccharides can accumulate in the complex multi-layered cell walls of microalgae, making them a preferred raw material for fermentation to produce bioethanol (Giordano & Wang, 2018). Most microalgal biomass requires enzymatic hydrolysis prior to bioethanol production (Sun & Cheng, 2002).The major drawbacks of first-generation (from food crops such as maize [Zea mays], rice, or sugarcane) and second-generation (from lignocellulosic feedstock) bioethanols are overcome by algal bioethanol (Chen, Zhang, Li, et al, 2014). Under appropriate culture conditions, many algal species accumulate large amounts of ethanol if the substrates can be fermented (Bibi et al, 2017;de Farias Silva & Bertucco, 2016).…”

Microalgal hydrogen production research

“…Heterotrophic H 2 -production by microalgae has received attention, as it holds the potential of waste chemicals biodegradation [127,130,131], generating, in addition to H 2 , a variety of end-products such as acetate, formate, lactate, ethanol, glycerol, butanediol, and carbon dioxide from the intracellular anaerobic waste compound catabolism [21,132e134]. Sources of potentially useful wastewater compounds in the literature are olive mill wastewater [127]; urban wastewater [135]; starch wastewater [136]; corn stalk [137]; sweet sorghum stalks [131]; dark fermentation effluent [130]; and landfill-leachate [138].…”

It was reported that Chlorella vulgaris MSU 01, isolated from a pond sediment, could generate H 2 from corn stalk (1e5 g/L) via anaerobic fermentation, and also elevate the butyrate concentrations of the fermentation effluent [137].…”

“…It was reported that Chlorella vulgaris MSU 01, isolated from a pond sediment, could generate H 2 from corn stalk (1e5 g/L) via anaerobic fermentation, and also elevate the butyrate concentrations of the fermentation effluent [137]. C. reinhardtii was also reported to be capable of producing H 2 from wastewater samples derived after the pressing stage of fermented sweet sorghum stalks during an "advanced solid state fermentation" process [131]. The major carbon compounds of this wastewater included sucrose, glucose, fructose, acetic acid and butyric acid.…”
