However, there are different factors, which limit the biogas production
such as requirement of larger land area, infrastructure,
and heat for the digesters (Collet et al., 2011; Jones and Mayfield,
2012). The proteins present in algal cells increases the ammonium
production resulting in low carbon to nitrogen ratio, which affects
biogas production through the inhibition of growth of anaerobic
microorganisms. Also, anaerobic microorganisms are inhibited by
the sodium ions. Therefore, it is recommended to use the salt tolerating
microorganisms for the anaerobic digestion of algal biomass
(Yen and Brune, 2007; Brennan and Owende, 2010; Jones and
Mayfield, 2012).
