        Hypolipidemic and Antiatherosclerotic Potential of Pleurotus ostreatus, Cultived by Submerged Fermentation in the High-fat Diet Fed Rats

        Leandro Freire dos Santos,Ana Lucia Zanatta,Vanete Thomaz Soccol,Maria Fernanda Torres,Sandro José Ribeiro Bonatto,Rosália Rubel,Carlos Ricardo Soccol 한국생물공학회 2013 Biotechnology and Bioprocess Engineering Vol.18 No.1

        The ability of Pleurotus ostreatus biomass,cultived by submerged fermentation, to produce beneficial effect on lipid profile and macrophages activity during a high-fat diet (HFD) for a long-term intake was investigated. Blood samples were collected through cardiac puncture to measure the plasma cholesterol, triglycerides, low-density protein (LDL), high-density protein (HDL), aspartate aminotransferase (AST) activity, urea– blood urea nitrogen (BUN)/creatinine ratio of rats fed on an HFD for 4 months. Dosage of lipid hydroperoxides was carried out on methanolic extract of liver tissue. Peritoneal macrophages activity was evaluated in relation to the superoxide anion,hydrogen peroxide and nitric oxide production, phagocytosis and lysosomal volume. The administration of P. ostreatus significantly altered the lipid profile and oxidative stress as related to the LDL and triglycerides decrease and inhibitory effects on superoxide anion and hydrogen peroxide production. All findings of this study lead us to suggest that the P. ostreatus maybe a beneficial agent in the hyperlipidemia and atherosclerosis treatments.

        Soybean Molasses-based Bioindicator System for Monitoring Sterilization Process: Designing and Performance Evaluation

        Sandra Regina B. R. Sella,Carla Masetti,Luis Felipe M. Figueiredo,Luciana P. S. Vandenberghe,João Carlos Minozzo,Carlos Ricardo Soccol 한국생물공학회 2013 Biotechnology and Bioprocess Engineering Vol.18 No.1

        A novel cost-effective Bacillus atrophaeus Sterilization Bioindicator System (BIS) with a high quality and performance was developed from a soybean byproduct and compared with the commercial BIS. It was composed of recovery medium and dry-fermented spores with sand as the support. The BIS was developed and optimized using a sequential experimental design strategy. The recovery medium contained soluble starch (1.0 g/L),soybean molasses (30.0 g/L), tryptone (40.0 g/L), and bromothymol blue (0.02 g/L) at pH 8.5. The solid-state fermentation conditions of the bioreactor and environmental humidity had no significant effects on the spore yield and dry-heat resistance. The only substrate mineral that showed a positive effect was Mn2+, allowing Mg2+, K+, and Ca2+ to be eliminated from the formulation. Validation of optimized medium indicated D160°C = 6.8±1.0 min (3.6 min more than the minimum) and spore yield = 2.3 ± 0.5 × 109 CFU/g dry sand (10,000 × initial values). BIS performance resulted in D160°C = 6.6 ± 0.1 min. Sporulation and germination kinetics allowed the sporulation process to be reduced to three days, and the growth of heat-damaged spores was sufficient to achieve visual identification of a non-sterile BIS within 21 h. Process economics was a minimum of 23.9%, and process cycle time was reduced from 29 to 15days. The new BIS parameters demonstrated compliance to all regulatory requirements. No studies have yet described a BIS production from soybean molasses.

        Study of Some Parameters which Affect Xylanase Production: Strain Selection, Enzyme Extraction Optimization, and Influence of Drying Conditions

        Giselle Maria Maciel,Luciana Porto de Souza Vandenberghe,Ricardo Cancio Fendrich,Bianca Eli Della Bianca,Charles Windson Isidoro Haminiuk,Carlos Ricardo Soccol 한국생물공학회 2009 Biotechnology and Bioprocess Engineering Vol.14 No.6

        Xylanases are glycosidases mainly responsible for the hydrolysis of β-1,4 linkages in xylan. Xylanase was produced in this work by solid-state fermentation using agro industrial residues with Aspergillus niger strain, which was screened through qualitative and quantitative methods. Extraction processes with different solvents were evaluated. Solvent volume, time, and agitation speed (shaker) were optimized using statistical designs. Drying studies of the solid fermented material were also conducted in a laboratory oven where the following conditions were applied: 42oC and 50oC for 20 h and 80oC for 1 h; 50oC and 75oC for 6 and 3 h, respectively. Best extraction conditions were 37 mL of solvent composed by NaCl solution (0.9%) with Tween 80 (0.1%) in 3 g of cultured material with agitation at 133 rpm in shaker for 4 min. Highest xylanase activity was 2,327 IU/gdm. The drying at 42oC for 20 h provided a better maintenance of xylanase activity (58% of xylanase activity).

        Medicinal Mushroom Ganoderma lucidum (Leyss: Fr) Karst. Triggers Immunomodulatory Effects and Reduces Nitric Oxide Synthesis in Mice

        Rosália Rubel,Herta S. Dalla Santa,Sandro J.R. Bonatto,Se´rgio Bello,Luiz Cla´udio Fernandes,Raffaello Di Bernardi,Juliana Gern,Cid Aimbire´ M. Santos,Carlos Ricardo Soccol 한국식품영양과학회 2010 Journal of medicinal food Vol.13 No.1

        This study investigated the effect of Ganoderma lucidum supplementation on lymphocytes and peritoneal macrophages from mice. Our results show that G. lucidum in vivo was able to increase interferon-γ (IFN-γ) concentration but reduced CD3+ and CD8+ spleen lymphocytes. Ex vivo, IFN-γ; and interleukin-10 levels were increased and the tumor necrosis factor-α (TNF-α) level was reduced by peritoneal macrophages from mice fed with G. lucidum. In the absence of stimuli nitric oxide production was reduced in mice fed with G. lucidum, and with lipopolysaccharide stimulation nitric oxide production was increased but was lower than control values (P<.05). G. lucidum was grown by solid-state culture in wheat grain, and a chow containing 10% G. lucidum mycelium was formulated (G10). Swiss male mice were divided into two groups, termed G10 and control groups according to the diet, and were fed for 3 months. Peritoneal macrophages were obtained and investigated with regard to phagocytosis, lysosomal volume, hydrogen peroxide, superoxide anion, and cytokines ex vivo. In the plasma we investigated concentrations of cytokines, and in the spleen we determined subsets of CD3+, CD4+, CD8+, and CD19+ lymphocytes.
