“…Based on the obtained experimental data, six factors having significant influence on the 2,3-butanediol production were selected for the present Taguchi DOE study to optimize the submerged culture condition. Six factors (temperature, pH, agitation, inoculum's size, acetic acid and succinic acid) which showed significantly influence on the 2,3-butanediol production (Perego et al, 2000;Ghosh and Swaminathan, 2003;Perego et al, 2003) were considered in the present experimental situation ( Table 1).…”

2,3-Butanediol production parameter optimization using Klebsiella pneumoniae PTCC 1290 was performed using the design of experiments available in the form of an orthogonal array and a software for automatic design and analysis of the experiments, both based on Taguchi protocol. Optimal levels of physical parameters and key media components namely temperature, pH, inoculum size, agitation, acetic acid and succinic acid were determined. 2,3-Butanediol production obtained from the 18 sets of fermentation experiments performed with the selected factors and levels were further processed with Qualitek-4 software at bigger is better as quality character. The optimized conditions showed an enhanced 2,3-butanediol production of 35.8% (from 11.856 to 18.459 g l -1). The optimal combinations of factors obtained from the proposed design of experiments methodology was further validated by conducting fermentation experiments and the obtained results revealed an enhanced 2,3-butanediol production of 25.8%. Taguchi approach of design of experiments resulted in evaluating the main and interaction effects of the factors individually and in combination.

“…With B. licheniformis corn starch hydrolysates were applied to 2,3-BDO production (Perego et al, 2003). With E. aerogenes, food industry wastes such as starch hydrolysates, raw and decoloured molasses, and whey permeate were used for the fermentation of 2,3-BDO (Perego et al, 2000). The use of lignocellulosic compounds for 2,3-BDO has also been reported, e.g.…”

In Chapter 1 it is reported the cellulase production by 4 marine-derived fungi strains (Aspergillus sydowii CBMAI 934, A. sydowii CBMAI 935, Penicillium citrinum CBMAI 1186 and Mucor racemosus CBMAI 847) and 1 terrestrial fungi strain (Aspergillus sp. CBMAI 1198). They were grown in solid state fermentation using wheat straw as substrate (5 g) and with addition of peptone solution (0,75 g.L -1 ) enriched with inorganic salts. It was performed the enhancement of the growth conditions by changing the temperature, initial pH and moisture. The optimum temperature for all strains varied between 25-35 °C but A. sydowii CBMAI 935 with 40 °C. The optimum pH was different for each strain, varying from acidic to alkaline conditions. The optimum moisture content also varied accordingly the studied strain. In order enhance the cellulose hydrolysis performed by the produced cellulases, it was varied the pH, temperature and amount of the crude cellulase extract during the filter paper hydrolysis reaction. The obtained optimum values were different among strains and, in some cases, there were two optimum pH and temperature for the hydrolysis of the filter paper. Then, the obtained cellulases, using the best conditions for hydrolysis, were used in the sugarcane bagasse hydrolysis (10 FPU/g of sugarcane bagasse). The cellulases from the strains Aspergillus sp. CBMAI 1198 and A. sydowii CBMAI 934 were capable of degrading 75% and 78% of the sugarcane bagasse, respectively, generating reducing sugars. In Chapter 2, the capability of 6 strains (Bacillus subtilis LQOB-SE1, B. coagulans LQOB-SE2, B. pumillus LQOB-SE3, Brevibacillus brevis LQOB-SE4, Lysinibacillus sp. LQOB-SE5 and Serratia marcescens LQOB-SE6), isolated from peat soil, of producing 2,3-butanediol from glycerol fermentation. The only strain that produced 2,3-butanediol was S. marcescens LQOB-SE6, which was also applied in 2,3-butanediol production from glucose fermentation. Therefore, wastes from biodiesel and bioethanol production can be reused in industrial scale. The best conditions for glycerol fermentation: initial pH 7, Nutrient Broth (8 g. Tabela 3.
