Biomass of the blue–green alga Spirulina maxima was converted to methane using continuous stirred tank digesters with an energy conversion efficiency of 59%. Digesters were operated using once‐a‐day feeding with a retention time (θ) between 5 and 40 days, volatile solid concentrations (Sto) between 20 and 100 kg VS/m3, and temperatures between 15 and 52°C. The results indicated a maximum methane yield of 0.35 m3 (STP)/kg VS added at θ 30 days and Sto 20 kg VS/m3. Under such conditions, the… 
Anaerobic Digestion of Laminaria digitata: The Effect of Temperature on Biogas Production and Composition
A drop in pH in the mesophilic and thermophilic reactors was identified as an inhibitory factor during the first days of digestion, and psychrophilic reactors were better able to withstand the observed changes.
Anaerobic digestion of the microalga Spirulina at extreme alkaline conditions: biogas production, metagenome, and metatranscriptome
Metagenomic and metatranscriptomic analysis showed that the hydrolysis of the supplied substrate was mainly carried out by Bacteroidetes of the “ML635J-40 aquatic group” while the hydrogenotrophic pathway was the main producer of methane in a methanogenic community dominated by Methanocalculus.
Anaerobic digestion of microalgal biomass : effects of solid concentration and pre-treatment
Microalgae have recently attracted considerable attention as a potential substrate for biofuel production. Through the anaerobic digestion process, microalgal biomass can be converted to biogas.
Downstream application of a microbial fuel cell for energy recovery from an Arthrospira maxima fed anaerobic digester effluent
Anaerobic digestion of Arthrospira maxima biomass produced an effluent stream that consisted of residual organic compounds not converted into biogas. Further polishing of the effluent presented the
Anaerobic digestion of Spirulina sp. and Scenedesmus sp.: a comparison and investigation of the impact of mechanical pre-treatment
Spirulina, possibly due to a combination of osmotic shock, the filamentous nature of the cells and lower mechanical strength of the non-cellulosic cell wall, was more readily degraded by hydrolytic and acidogenic microorganisms, resulting in the generation of a greater amount of acetic acid which provided greater substrate for methanogens and hence higher methane yields.
Cyanobacterial Biomass Produced in the Wastewater of the Dairy Industry and Its Evaluation in Anaerobic Co-Digestion with Cattle Manure for Enhanced Methane Production
The unique perspective that microalgae biomass presents for bioenergy production is currently being strongly considered. This type of biomass production involves large amounts of nutrients, due to


Thermophilic methane production from cattle waste
It is indicated that loading rates can be much higher than those previously thought useful for maximizing methanogenesis from cattle waste, and methane production from waste of cattle fed a finishing diet was investigated, using four 3-liter-working volume anaerobic digestors.

Results on the anaerobic inoculum development by the adaptation technique were presented, and it appeared that the fermentability of S. maxima algal biomass is significantly higher than other microscopic algae.
Multistage continuous cultivation of blue‐green alga spirulina maxima in the flat tank photobioreactors with recycle
Spirulina maxima was continuously cultivated in four 64-liter flat tank photobioreactors in cascade, under continuous 30 klx fluorescent light and nonaseptic condition, in an industrial grade

Batch fermentations showed that the ultimate CH4 yield (B0) of straw–manure mixtures was directly proportional to the relative proportion and B0 of the individual components, and hammer or ball milling did not increase the B 0 of straw.
Utilization of seawater-urea as a culture medium for Spirulina maxima.
The possibilities of utilization of seawater enriched with ureas as the culture medium for a blue-green alga, Spirulina maxima, were investigated and growth of S. maxima was inhibited at higher concentration of urea in the culturemedium.
Temperature effects on anaerobic fermentation of domestic refuse
Anaerobic fermentation of organic solid waste can provide a significant source of fuel gas (methane). Application of this process requires a better understanding of the kinetics of the biological
Use of pH and pE measurements during methane biosynthesis
Experimental evidence is presented which supports the possible use of pH and pE determinations for process evaluation and control and theoretical and practical limitations are discussed.
An enzyme coimmobilized with a microorganism: The conversion of cellobiose to ethanol using β‐glucosidase and Saccharomyces cerevisiae in calcium alginate gels
The coimmobilized preparation was superior to a combination of separately immobilized biocatalysts, however, in this preparation, one‐half the enzyme activity was lost within a week when incubated at the operational temperature in the absence of substrate.
