The use of rice straw (RS) was enhanced to produce biobutanol as biofuel, for which the NaOH pretreatment optimized by considering butanol-biomass ratio that quantify mass balance efficiency three sequential stages process: pretreatment, enzymatic hydrolysis and fermentation Clostridium beijerinckii. optimum point (solid loading 5% w/v with 0.75% at 134 °C 20 min) best cost-wise option yielded an biomass 77.6 g kg RS−1. A maximum butanol titer 10.1 L−1 reached after 72 h complete uptake...
Abstract One of the challenges in biofuel production from lignocellulosic wastes is to improve its conversion solvents; therefore, new strategies enhance xylose uptake are required due be secondary abundant sugar. In this context, a novel fermentation strategy integrating co-culture Clostridium acetobutylicum and Saccharomyces cerevisiae with pH control was developed. Initially, two different buffers, ammonium acetate calcium carbonate, were tested under min > 4.8 by fermenting 60 g L −1...
Abstract BACKGROUND: Two peat biofilters were used for the removal of toluene from air one year. One biofilter was fed with pure and other received 1:1 (by weight) ethyl acetate:toluene mixture. RESULTS: The operated under continuous loading: inlet load (IL) at which 80% occurred 116 g m −3 h −1 57 s gas residence time. Maximum elimination capacity 360 obtained an IL 745 . inhibited by presence acetate. Intermittent loading, pollutants supplied 16 h/day, 5 days/week, did not significantly...
A 0.75-m3 pilot-scale biotrickling filter was run for over 1 yr in a Spanish furniture company to evaluate its performance the removal of volatile organic compounds (VOCs) contained emission two different paint spray booths. The first one an open front booth used manually furniture, and second focus automatically operated closed pieces furniture. In both cases, VOC emissions were very irregular, with rapid extreme fluctuations. pilot plant at empty bed residence time (EBRT) ranging from 10...
Microbial biofilms are essential components in the elimination of pollutants within biofilters, yet still little is known regarding complex relationships between microbial community structure and biodegradation function these engineered ecosystems. To further explore this relationship, 16S rDNA tag pyrosequencing was applied to samples taken at four time points from a styrene-degrading biofilter undergoing variable operating conditions. Changes were observed different stages operation, level...
Abstract Three laboratory‐scale peat biofilters were operated at 90 s empty bed residence time (EBRT) for over a year. Biodegradation of ethyl acetate, toluene, or 1:1 mixture investigated. In first stage, inlet concentration was progressively increased from 0.4 to 4.5 g/m 3 . The maximum elimination capacity (EC) found acetate 190 gC/m ·h, and it not affected by toluene. EC toluene as sole contaminant 150 but the presence decreased 80 ·h. From respirometry monitoring, values 3.19 g CO 2 /gC...
BACKGROUND: One of the most important industrial sources volatile organic compounds (VOCs) is related to coating and painting applications. In this sense, photocatalytic oxidation can become an innovative promising alternative for remediation air polluted by VOCs. study UV photodegradation m-xylene, toluene n-butyl acetate, as representative paint solvents, was carried out in annular reactor using a TiO2–glass wool supported catalyst. RESULTS The removal each component their mixture,...
This paper describes a study of fed-batch SSFR (simultaneous saccharification, fermentation and recovery) for butanol production from alkaline-pretreated rice straw (RS) in 2-L stirred tank reactor. The initial solid (9.2% w/v) enzyme (19.9 FPU g-dw-1) loadings were previously optimized by 50-mL batch SSF assays. Maximum concentration 24.80 g L-1 was obtained after three biomass feedings that doubled the RS load (18.4% w/v). Butanol productivity (0.344 L-1h-1) also increased two-fold...
