“…Different agricultural wastes (e.g. sugar cane bagasse, corn stover, elephant grass, fruit pomace and straw or bran from wheat, rice or corn) have been applied for enzyme production [28,[57][58][59][60][61][62][63]. These agricultural residues can also be used as potential biomass sources for biorefineries, and are therefore ideal for a CBP setup.…”

“…Even though some reports have commended that cellulases could be produced by Penicillium genera (Zynai et al 2009;Long et al 2009;Picart et al 2007), relatively little information of optimization of solid-state fermentation conditions of cellulases production by Penicillium chrysogenum using response surface methodology is available. Therefore, this work will provide a new reference in this field.…”

“…Most bacteria cannot utilize crystalline cellulose, which can be done by many filamentous fungi strains. Therefore, cellulolytic fungi such as Trichoderma (Rocky-Salimi and Hamidi-Esfahani 2010; Latifian et al 2007), Aspergillus (Soni et al 2010;Gao et al 2008), Penicillium (Long et al 2009), and Fusarium (Panagiotou et al 2003) genera are well known to secrete cellulases in large amounts.…”

Solid-state fermentation conditions for cellulases production by a newly isolated Penicillium chrysogenum QML-2 were investigated using statistical methods. At first, significant variables for cellulases production including (NH(4))(2)SO(4), initial pH and inoculum size were screened by using Plackett-Burman Design. Then the optimal regions of the significant variables were investigated by using the method of steepest ascent. Finally, central composite design and response surface analysis were adopted to determine the optimal values of the significant variables and investigate the combined effects of each variable's pair on cellulases production. The results showed that the optimal ranges of (NH(4))(2)SO(4) concentration, initial pH and inoculum size for three types of cellulases activities were 1.97-2.15 g, pH 4.32-4.41 and 13.3-13.7% (v/w), respectively. Using the mixture of corn stover powder and wheat bran (CSP/WB, 1/1) as carbon source, the optimization resulted in 370.15, 101.76 and 321.56 U/g for maximal endoglucanase activity, filter paper activity and β-glucosidase activity, respectively. Compared with maximum values of cellulases activities (endoglucanase activity 85.21 U/g, filter paper activity 16.62 U/g and β-glucosidase activity 67.68 U/g) obtained under unoptimized conditions, the optimization resulted in 3.34, 5.12 and 3.75 folds improvement for endoglucanase activity, filter paper activity and β-glucosidase activity, respectively. For chitosan hydrolysis, the crude cellulases had the optimal temperature of 55°C, pH of 4.4 and exhibited Michaelis constant (K (m)) value of 8.34 mg/ml and maximum velocity (V (max)) of 2.21 μmol glucosamine/min by 1 ml of the crude cellulases.

“…However, this method cannot guarantee the determination of optimal conditions and is unable to study the interactions between the factors, thus probably leads to unreliable results and inaccurate conclusions. [13] Response surface methodology (RSM), the statistical optimization method, uses the data from a few sets of experiments to determine equations. This method can overcome the limitations of the classical method and has been proved to be a powerful tool for designing experiments, building models, evaluating the effects of factors and analysing optimal conditions of factors for desirable responses.…”

Saccharomyces boulardii preparations are promising probiotics and clinical agents for animals and humans. This work focused on optimizing the nutritional conditions for the production of S. boulardii in solid-state fermentation by using classical and statistical methods. In single-factor experiments, the S. boulardii production was significantly increased by the addition of glucoamylase and the optimal carbon and nitrogen sources were found to be soluble starch and NH 4 Cl, respectively. The effects of the glucoamylase, soluble starch and NH 4 Cl on S. boulardii production were evaluated by a three-level three-factor BoxÀBehnken design and response surface methodology (RSM). The maximal yeast count (4.50 £10 9 CFU/g) was obtained under the optimized conditions (198 U/g glucoamylase, 2.37% soluble starch and 0.9% NH 4 Cl), which was in a good agreement with the predicted value of the model. This study has provided useful information on how to improve the accumulation of yeast cells by RSM.
