Clostridium Phytofermentans

Ethanol produced from lignocellulosic biomass is an alternative transportation fuel with the potential to lower greenhouse gas emissions and increase energy security. Source-separated organic waste (SSO) from the city of Toronto was investigated for feasibility as a lignocellulosic ethanol feedstock. Clostridium phytofermentans is a mesophilic, cellulolytic and ethanologenic species with potential application for ethanol production from lignocullulosic biomass. C. phytofermentans was considered for biofuels production through experiments on a variety of substrates including soluble sugars and pure celluloses. Results from this study found that C. phytofermentans produced 73% of the theoretical ethanol yield on cellobiose but grew poorly on glucose and xylose. In addition, C. phytofermentans grew marginally on microcrystalline and ball-milled cellulose, but with supplemental enzymes produced 55% of the theoretical ethanol yield.

The fossil energy sources used in the world are gradually decreasing and limited. Fossil fuels cause environmental pollution, and the unit price is constantly increasing. For this reason, demand for cheaper and renewable energy sources that do not pollute the environment is increasing day by day. The sweet sorghum plant has attracted attention in recent years with its high biomass yield, sugar content and bioethanol yield. In this study, it was aimed to determine the bio-fuel potential of some sweet sorghum genotypes in semi-arid climatic conditions. The experiment was set up in randomized complete block design with 4 replicates. Research was carried out in 2015 under Harran Plain (36o 42’ N and 38o 58’ E) second crop conditions, Sanliurfa, Turkey. In the study 49 genotypes of sweet sorghum were used. Stalk yield, juice yield, syrup yield, brix, sugar yield and theoretical ethanol yield were determined in the study. Significant differences were found between the genotypes for tested characteristics (P≤0.01). Stalk yield ranged from 7110.0 kg da-1 to 24262.5 da-1, juice yield from 2550.0 L da-1 to 12187.5 L da-1, syrup yield from 291.4 L da-1 to 2242.5 L da-1. Also, brix value varied between %7.0 and %18.87, sugar yield between 247.7 da-1 and 1906.1 da-1, Theoretical ethanol yield between 131.9 L da-1 and 1014.8 L da-1. Considering to stalk yield, juice and syrup yield, brix, sugar yield and theoretical ethanol yield; Nebraska sugar, Topper 76, Smith, M81E and Corina genotypes were found as the best. As a result of research, 21 genotypes with better performance than the others were selected for further studies.

Pre Treatment

<p>Lignocellulosic biomasses are promising alternative resource for bio-fuel production. But due to the recalcitrant nature of lignin and hemicellulose, necessitates an efficient pre-treatment process to improve the yield of reducing sugars and maximising the enzymatic hydrolysis efficiency. Catalysed-microwave pre-treatment may be a good alternative as compared to other methods since it can reduce the time and improve the enzymatic activity during hydrolysis. The aim of this study was to evaluate the efficiency of the catalysed-microwave based pre-treatment of lignocellulosic biomass of Camelina sativa straw (CSS) to overcome the recalcitrant nature of cellulosic biomass. The microwave-alkaline (2 % NaOH) pre-treatment of CSS at 250 W for 10 min yields maximum (~422 mg/g) total soluble sugars (TSS) production during hydrolysis. Likewise, the maximum glucose content (~294 mg/g) was measured in 2 % alkaline-microwave pre-treatment for 10 min at RT. However, slight increase in lignin degradation was observed with the increase in alkaline hydroxide concentration and microwave irradiation exposure time. The maximum degradation in lignin content (~83 %) was measured in 3 % alkaline-microwave pre-treatment for 20 min at RT. Our results suggest that the microwave-alkaline pre-treatment approach may be employed for comprehensive utilisation of CSS biomass of Camelina sativa L. cv. Calena (EC643910) for bio-fuel production.</p>

A field experiment was carried out to study the growth characteristics of switchgrass cultivated in saline-alkali lands. The results show that: the survival rate, plant height, tiller numbers per plant and biomass yield of switchgrass significantly reduce with the increasing magnitude of salinity-alkalinity stresses. Switchgrass can grow in saline-alkali environments, the survival rate is more than 85%, and the overwintering rate is more than 95%. Switchgrass plants grow better in mild and moderate saline-alkali lands, and it achieve the highest biomass yield and theoretical ethanol yield of 14.3 t/ha and 5958.8 l/ha respectively, in the third year. With saline-alkali stress, ash and lignin content of switchgrass biomass increase, calorific value, cellulose and hemicelluloses content of switchgrass biomass decrease, and fuel quality of switchgrass biomass reduce to a certain extent.

Waste has become a problem that is really worrying everywhere. If you pay close attention, there are indeed a number of factors that cause waste problems to become serious. First, population growth. Second, more and more instant food with plastic packaging. Third, the habit of littering, the habit of consuming instant food in packaging, to the habit of throwing garbage without sorting between organic and non-organic waste will damage the ecosystem. The same problem is also experienced by Berbek Village in Sidoarjo Regency, the problem of waste and flooding that is always faced by the city cannot only be the responsibility of the government, but the community as one of the producers of household waste should always help reduce the amount of waste. Thisneeds to provide an understanding to the community of environmental concerns, especially regarding household waste management and water conservation for the future based on water conservation. The results achieved from this activity are that the village community is aware of and understands the importance of a clean environment, there is no garbage scattered, puddles or floods can be reduced, and are able to practice independent waste management methods.
