| Abstract |
Ethanol production from low severity pretreated (85 °C, 1 h) solid household waste was studied using simultaneous saccharification and fermentation (SSF). The aim of the study was to examine typical composition of the organic fraction of municipal solid waste (OFMSW) and to develop a simple method for simultaneous liquefaction and biofuels production. A model waste was prepared based on the composition of the organic waste in Masdar City. Chemical analysis of the OFMSW showed that it contained 37 % total solids with up to 57 g glucan/100 g total solid (TS). Hydrolysis of the wet OFMSW was carried out using a mix of hydrolytic enzymes: amylase, cellulase, protease, lipase, hemicellulase, and pectate lyase. The enzymatic hydrolysis using this enzyme mix was studied using different dilutions of the OFMSW at different enzyme loadings. This study has demonstrated that SSF of low severity pretreated OFMSW can be carried out using Saccharomyces cerevisiae without dilution (addition of water), and liquefaction of the undiluted OFMSW can be achieved in less than 24 h of hydrolysis. Also, SSF of the pretreated waste can be carried out with very low enzyme loading (10 % of the company recommended dosage)-0.1 % cellulase, 0.1 % amylase, 0.02 % protease, 0.02 % hemicellulase, 0.02 % lipase, and 0.02 % pectate lyase (w/w per TS) following mild heat pretreatment conditions of 85 °C for 1 h. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 October 2014.
All research outputs
#13,806,311
of 24,119,703 outputs
Outputs from Applied Microbiology and Biotechnology
#5,185
of 8,034 outputs
Outputs of similar age
#110,575
of 241,616 outputs
Outputs of similar age from Applied Microbiology and Biotechnology
#39
of 99 outputs
Altmetric has tracked 24,119,703 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,034 research outputs from this source. They receive a mean Attention Score of 4.3. This one is in the 35th percentile – i.e., 35% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 241,616 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 53% of its contemporaries.
We're also able to compare this research output to 99 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
