Abstract :

Global warming is caused due to the increasing amount of green house gases to the atmosphere. About 73% of the CO2 is liberated due to fossil fuel. So, there is an urgent need for the alternative energy to solve the above problems. Recently, bioethanol, biodiesel and biogas have been used worldwide. Among them, bioethanol is the leading alternative energy derived from the various lignocelluloses substrates such as vegetable wastes, fruit peels, wheat straw, sugar beet, corn, paddy straw, wood and agricultural wastes. Large amount of seagrass has been deposited in the Palk Strait region when compared with the other coastal regions of Tamil Nadu. The deposited seagrass on the shore produce unpleasant odour along the coast which may create an anoxic condition to the marine organisms. The present study made an attempt to find out the possible bioethanol production from seagrass wastes by using marine microbes and thus it also helps to clean-up the coastal areas. The present study has surveyed seagrass resources along the coastline of 168 Km long by considering several coastal land forms. Experiments were conducted with pretreated seagrass biowastes as substrate at different pH and incubation time for the ethanol production by isolated marine yeasts. The potential isolates were identified through molecular techniques and deposited in the GenBank under the accession number JF922862, JF922863, JF922864 and JF922865. The pretreated biomass were characterised through FT-IR, XRD, TGA- DTA, SEM and thermal stability analysis. The spent wastes were also reutilized for the cultivation of milk mushroom Calocybe indica
