The aim of this study was to use Alpha-amylase termamyl 2-x for maltodextrin production from corn starch and evaluate its industrial uses. Based on the results obtained in laboratory, this process was accomplished in pilot plant scale. The process included preparation of starch suspension, pH adjustment, addition of enzyme, heating under stirring, continuous control of DE and Brix, enzyme inact...
We demonstrated the feasibility of fedbatch operation using Clostridium acetobutylicum suspension culture as a biocatalyst for the continuous production of hydrogen. The optimum operating pH and temperature of the current cultivation system for hydrogen production were pH 6.0 and 37 degrees C, respectively. The volumetric loading of the bioreactor for hydrogen production can be as high as 650 m...
Steel production is an extremely complex process and finding its coherent schedules for the wide variety of production steps in a dynamic environment, where disturbances frequently occur, is a challenging task. In the steel production process, the blast furnace continuously produces liquid iron, which is transformed into liquid steel in the melt shop. The majority of the molten steel passes thr...
Introduction: Iodine deficiency and associated disorders, which lead to a wide range of clinical manifestations, have been raised as one of the health and nutritional problems in Iran. Therefore, this study was aimed to investigate the amount of iodine in distributed salts in Abarkouh city in 2017-2018. Materials and Methods: Random sampling was done by census on all 30 distributed brands in A...
During the federal funding program ‘New Media in Education’, a project group was established, which produces learning contents for two E-Learning offerings of an international virtual university: Process Modeling and Knowledge Management. The continuous improvement and development of the required production processes with the objective of creating professional and competitive learning units lea...
This review is a synopsis of different bioprocess engineering approaches adopted for the production of marine enzymes. Three major modes of operation: batch, fed-batch and continuous have been used for production of enzymes (such as protease, chitinase, agarase, peroxidase) mainly from marine bacteria and fungi on a laboratory bioreactor and pilot plant scales. Submerged, immobilized and solid-...
Micro-economic theory defines productions as the process of transforming inputs (production factors) into outputs (products). In order to explain efficient production and to provide means to select the best alternative from a set of possible production processes, two fundamental theories have been developed: The so called activity analysis [KOOPMANS 51] and the theory of production corresponden...
The French national agency for old age pensions has evolved, along a systemic vision of all the issues to be covered, a generic set of tools to design and process structured file formats. This set of tools has turned into a production grade modeling and validating suite which relies for its distribution on the continuous integration of its various components. As such, continuous integration has...
