Once a protein purification scheme has been developed, the purification, characterization, and use/structure of a target protein are usually published. It is highly desirable to present the major steps in the purification and the corresponding features of the protein at each step summarized in the form of a purification summary table. In considering whether to repeat a published protein purific...

Citric acid is the most widely used organic acid in the field of foods and beverages as an acidulant as well as in pharmaceutical and chemical products. Generally, surface or submerged fungal fermentation mainly with aspergillus niger is utilized for citric acid production. However, the submerged fermentation method is the most used method for citric acid production.1,2 The method of calcium sa...

The production of bio-based chemicals has received tremendous attention in recent years, but little has been done to understand the broad patterns of the economics of different processes for making these molecules. The diversity of potential chemicals simultaneously makes such an understanding both important and difficult to glean during these early-stages. By using cost correlations and standa...

As a production platform for recombinant proteins, plant leaf tissue has many advantages, but commercialization of this technology has been hindered by high recovery and purification costs. Vacuum infiltration-centrifugation (VI-C) is a technique to obtain extracellularly-targeted products from the apoplast wash fluid (AWF). Because of its selective recovery of secreted proteins without homogen...

Although schizophrenia affects only about 1% of the worldwide population, it is costly to patients, their families, community care centers, hospitals, and society. International cost of illness studies show a wide variation, with annual costs ranging from Australia's $139 million US dollars (1975) to the cost in the United States of $65.2 billion US dollars (1991). Since methodology and assumpt...

This research aims to study the relationship between the components of quality costs and quality in company. The relationship between the components of quality costs and quality in company has been studied separately for materials, manpower, machinery, and whole of company. In this study, traditional method was used to collect quality costs and PAF model was used to determine the components of ...

background: the presence of lead in natural waters has become an important issue around the world. lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. the aim of this work was to evaluate the adsorption of lead (pb(ii)) on waste tea leaves as a cheap purification method. methods: in this...

background and objectives: recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...
