Response surface methodology was used to enhance the production of α-galactosidase from Fusarium moniliforme NCIM 1099 in solid-state fermentation. Plackett-Burman design was employed for selection of critical media constituents which were optimized by central composite rotatable design. Wheat bran, peptone and FeSO4·7H2O were identified as significant medium components using PB design. Further...
Abstract—The composite flour blend consisting of corn, pearl millet, black gram and wheat bran in the ratio of 80:5:10:5 was taken to prepare the extruded product and their effect on physical properties of extrudate was studied. The extrusion process was conducted in laboratory by using twin screw extruder. The physical characteristics evaluated include lateral expansion, bulk density, water ab...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Chitosan is a biopolymer obtained from shrimp waste mainly by polluting chemical method. In this work, less biological-chemical method to obtain chitosan has been optimized; used successive lactic fermentation and process. Additionally, in the effect of coating on post-harvest behavior fresh-cut papaya was studied as practical application. A rotatable central composite design (CCRD) with two va...
Despite having remarkable features such as low density, ease of fabrication and recyclability, linear low-density polyethylene (LLDPE) has several drawbacks like poor stiffness creep resistance which fortunately can be improved by incorporating with other suitable nanofillers. In this study, graphene nanoplatelets (GNPs) that are well-known for its high surface area superior stability were sele...
Some mechanical and process parameters of a developed millet thresher have been optimized using numerical optimization technique. The machine threshes panicles cleans the grains from straw. speed threshing number pegs attached to drum were investigated, while moisture content was parameter under investigation. Threshing efficiency, cleaning percentage losses used as performance characteristics ...
Mineral carbonation incurs high operating costs, as large amounts of chemicals and energy must be used in the process. Its implementation on an industrial scale requires reducing expenditures consumption. Thus, this work aimed to investigate significant factors involved pH-swing mineral their effects CO2 capture efficiency. A central composite rotatable design (CCRD) was employed for optimizing...
The vegetal species Arachis repens, commonly known as peanut grass, was studied and, for the first time, we detected the presence of the bioactive compound trans-resveratrol (t-RSV). We compared the efficiency of three different methodologies (conventional maceration [CM], ultrasound-assisted extractions [UAE], and microwave-assisted extractions [MAE]) concerning total phenolics (TP) and resver...
Tinctures are medicinal plant extracts obtained by extraction with a hydroalcoholic solution (70%) percolation (PER). This process takes about 26 h to prepare, in addition using large amount of solvent. In our research, passion fruit leaf tinctures were extract the same pressurized as an intermittent process. The objective was demonstrate that this emerging technology can be economical and prof...
Response surface methodology (RSM) was used to study the effect of three factors, sulfur dioxide, ethanol and glucose, on the growth of wine spoilage yeast species, Zygosaccharomyces bailii, Schizosaccharomyces pombe, Saccharomycodes ludwigii and Saccharomyces cerevisiae. Seventeen central composite rotatable design (CCRD) trials were designed for each test yeast using realistic concentrations ...
