Transcriptional Analysis Of Lactobacillus Brevis To N-Butanol And Ferulic Acid Responses, James Winkler, Katy Kao
Transcriptional Analysis Of Lactobacillus Brevis To N-Butanol And Ferulic Acid Responses, James Winkler, Katy Kao
Faculty Publications
BackgroundThe presence of anti-microbial phenolic compounds, such as the model compound ferulic acid, in biomass hydrolysates pose significant challenges to the widespread use of biomass in conjunction with whole cell biocatalysis or fermentation. Currently, these inhibitory compounds must be removed through additional downstream processing or sufficiently diluted to create environments suitable for most industrially important microbial strains. Simultaneously, product toxicity must also be overcome to allow for efficient production of next generation biofuels such as n-butanol, isopropanol, and others from these low cost feedstocks.Methodology and Principal FindingsThis study explores the high ferulic acid and n-butanol tolerance in Lactobacillus brevis, a …

With nearly 5,000 students, the Charles W. Davidson College of Engineering (CoE) at San José State University (SJSU) is the largest provider of engineers to Silicon Valley companies and is ranked 12th among engineering programs for master’s-level institutions in the 2009 U.S. News &World Report's listing of "America’s Best Colleges. “Our overarching theoretical model for student retention is based on Tinto’s model. We adapted this model, based on additional research, to address the needs of students at SJSU. According to this model, effective and positive interactions in college should increase the student’s commitment and effort in college, and thereby, increase …

One of the most significant challenges facing this coming generation of engineers is how to fight the complex issue of climate change. One aspect of this that is playing an increasingly important role is alternative and renewable energy technologies. Emerging applications such as solar cells, wind energy conversion devices, and fuel cells involve significant contributions across a range of traditional engineering disciplines. Therefore, for companies to be successful in researching, designing, and manufacturing these products, they must operate in a truly multi-disciplinary environment. To prepare graduates to be successful in this, engineering education must provide students with multi-disciplinary learning environments. …
Genomic Library Screens For Genes Involved In N-Butanol Tolerance In Escherichia Coli, Luis Reyes, Maria Almario, Katy Kao
Genomic Library Screens For Genes Involved In N-Butanol Tolerance In Escherichia Coli, Luis Reyes, Maria Almario, Katy Kao

Backgroundn-Butanol is a promising emerging biofuel, and recent metabolic engineering efforts have demonstrated the use of several microbial hosts for its production. However, most organisms have very low tolerance to n-butanol (up to 2% (v/v)), limiting the economic viability of this biofuel. The rational engineering of more robust n-butanol production hosts relies upon understanding the mechanisms involved in tolerance. However, the existing knowledge of genes involved in n-butanol tolerance is limited. The goal of this study is therefore to identify E. coli genes that are involved in n-butanol tolerance.Methodology/Principal FindingsUsing a genomic library enrichment strategy, we identified approximately 270 genes …

In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are presented. Additionally, the dynamic analysis results consist of the output pressure change versus time, the displacement of the moving parts versus time, the regulator mass flow rate versus time and the output pressure versus mass flow rate in different …
