Comparisons of existing pretreatment, saccharification, and fermentation processes for butanol production from agricultural residues
Authors: Thirmal Chumangalah , Dahman Yaser 
Published: August 2011

AbstractSome of the most recent, relevant, industrial and academic contributions made in the field of butanol production are reviewed here. The focus on butanol is due to the growing demand for non‐fossil biofuels. In addition, butanol can be mixed with fossil fuels or can be used alone, allowing an alternative to gasoline. Butanol can be synthesised biologically using sugars extracted from biomass such as agricultural waste. This agricultural waste must be pretreated before it is suitable for sugar extraction. Following this stage, enzymatic hydrolysis is employed, before performing fermentation using microorganisms. This article summarises some of the economical methods such as simultaneous saccharification and fermentation (SSF). Different pretreatment and saccharification processes were compared. Acid pretreatment and saccharification achieved the highest sugar concentrations from wheat straw. Monoethanolamine pretreatment achieved highest sugars from hardwood. Comparisons and analysis of different types of fermentation processes illustrated that immobilised reactor provided the best butanol rate of production. Integration of fermentation with product removal process improved butanol production in immobilised reactor. Gas stripping method was illustrated to be the product removal process. © 2011 Canadian Society for Chemical Engineering
Racial variation in tumor stage at diagnosis among Department of Defense beneficiaries

Published: August 2011

AbstractBACKGROUND:Tumor stage at diagnosis often varies by racial/ethnic group, possibly because of inequitable health care access. Within the Department of Defense (DoD) Military Health System, beneficiaries have equal health care access. The objective of this study was to determine whether tumor stage differed between whites and blacks with breast, cervical, colorectal, and prostate cancers, which have effective screening regimens, based on data from the DoD Automated Cancer Tumor Registry from 1990 to 2003.METHODS:Distributions of tumor stage (localized vs nonlocalized) between whites and blacks in the military were compared stratified by sex, active duty status, and age at diagnosis. Logistic regression was used to further adjust for age, marital status, year of diagnosis, geographic region, military service branch, and tumor grade. Distributions of tumor stage were then compared between the military and general populations.RESULTS:Racial differences in the distribution of stage were significant only among nonactive duty beneficiaries. After adjusting for covariates, earlier stages of breast cancer after age 49 years and prostate cancer after age 64 years were significantly more common among white than black nonactive duty beneficiaries (P < .05), although the absolute difference was minimal for prostate cancer. Racial differences in stage for cervical and colorectal cancers were not significant after adjustment. Compared with the general population, racial differences in the military were similar or were slightly attenuated.CONCLUSIONS:Racial disparities in stage at diagnosis were apparent in the DoD equal‐access health care system among older nonactive duty beneficiaries. Socioeconomic status, supplemental insurance, cultural beliefs, and biologic factors may be related to these results. Cancer 2012;. © 2011 American Cancer Society.
