Abstract:

Processing of lignocellulosic biomass for transportation fuels and other biocommodities in integrated biorefineries has been proposed as the future for emerging sustainable economies. Currently bioprocessing strategies are all multi-step processes involving extensive physicochemical pretreatments and costly amounts of exogenous enzyme addition. Consolidated bioprocessing (CBP), or direct microbial conversion, is a strategy that combines all the stages of production into one step, thus avoiding the use of expensive pretreatments and exogenous enzymes that reduce the economic viability of the p

Abstract:

The major objective of this thesis was to investigate and improve a direct microbial fermentation process, using the thermophilic anaerobic bacteria Clostridium thermocellum and Clostridium thermohvdrosulfuricum for the production of fuel ethanol in economically significant concentrations, from cellulose and hemicellulose contained in renewable biomass. Two model substrates representative of readily available lignocellulosic materials were selected for this study. These were wheat straw, which is the largest single biomass resource available in Australia, and waste paper, which is a major comp

Abstract:

The growth of thermophiles during the manufacture of milk powder leads to a progressive increase in the number of thermophilic bacteria contaminating the final product. The limited residence time of the milk in the plant during milk powder manufacture and the concentration effect of converting milk into milk powder cannot explain the number of thermophiles found in the final product. This suggests that thermophiles are attaching to the large surface area of stainless steel found within a milk powder plant and then growing and developing into biofilms, with individual cells and/or biofilm fragm

碩士<br>逢甲大學<br>化學工程學系<br>105<br>This study conducted the investigation of thermophilic hydrogen production from waste syrup used for beverage with CSTR (continuous flow stirred tank reactor) bioreactors by anaerobic mixed cultures. The effects of both hydraulic retention time (HRT) (18, 12, and 8 h) and substrate concentration (18.8-29.5 g ToSu/L; setting value 20, 25, and 30 g ToSu/L; ToSu: total sugar) on hydrogen fermentation were investigated. The results showed that high substrate concentration or low HRT not only resulted in decreasing substrate utilization but also shifting the metabolic

Tese de doutoramento em Engenharia Química e Biológica.<br>The main purposes of this thesis were the optimization of fermentation conditions for the production of biological antifouling agents, namely biosurfactants from probiotic bacteria, in order to develop new strategies for the prevention of microbial colonization of silicone rubber voice prostheses. Probiotic bacteria Lactococcus lactis 53 and Streptococcus thermophilus A were found to be biosurfactant¬producing strains. The improvement of the standard culture medium for biosurfactant production by response surface methodology, using a c
