Biogas from sea biomass would be a promising source of energy for replacing fossil-based fuels. Sea biomasses such as seaweeds and sea grasses can be used as an alternate feedstock for biomethanation as they have high carbohydrates and water content and low lignin. In this study, sea grasses such as Cymodocea serrulata and Syringodium isoetifoliuma and sea weed viz., Gracilaria salicornia found in Manalmekudi coast, Pudukottai district were collected and their characteristics were studied to assess its suitability for biogas production. Physico-chemical characteristics such as Total Solids, Volatile Solids, Total Organic Carbon and Nitrogen were determined. The C/N ratio of Cymodocea serrulata,Syringodium isoetifoliuma and Gracilaria salicornia were found to be 26.93, 29.19 and 22.81 respectively and hence all the three sea biomasses have very good biomethanation potential.
