Chitosan has received much attention as a functional biopolymer for diverse applications, especially in pharmaceutics and medicine. Chitosan is a positively charged natural biodegradable and biocompatible polymer.In this study, 3 different fungal strains Aspergillus niger NCIM1045, Aspergillus oryzae NCIM645 and Mucor indicus MTCC3318 were used for the production of chitosan. The produced chitosan was characterized by determining degree of dea...

Project Report from the year 2016 in the subject Energy Sciences, grade: 8, University of Petroleum and Energy Studies, language: English, abstract: The Indian subcontinent is blessed with an ample amount of sunlight almost all through the year. There is an urgent need of switching over to a perennial source of energy as an alternative to replace all the quickly depleting fossil fuels. There is much interest in non-conventional energy nowadays...

Cinnamon (Cinnamomum zeylanicum), is one of the highly prized fragrant spice that has been in use since biblical times for its medicinal and culinary properties.This novel spice is native to Sri Lanka but also found in many other countries. It is the bark of the tree from where aromatic essential oil (makes up 0.5% to 1% of its composition) is extracted.Cinnamon or Dalchini or Kirfa has antimicrobial, anti-clotting, anti-inflammatory, antispas...

Project Report from the year 2014 in the subject Biology - Micro- and Molecular Biology, grade: PDF, , course: Personal Research Project, language: English, abstract: Ancient rocks and natural oils are rich with abundant and hidden information of ancient organic matters responsible for earth formation, including molecular and isotopic signatures of the organisms that existed at the time the organic matter was formed. Considering the above fact...

Research Paper (undergraduate) from the year 2012 in the subject Chemistry - Bio-chemistry, grade: "-", , language: English, abstract: Extracellular alpha amylase was produced from Aspergillus oryzae under solid state fermentation. House hold agro-wastes were used as medium which were considered as one of the major pollutants due to unfavorable gas production via natural fermentation beside creating disposal problem. Investigations were carrie...

Thermophillic bacteria was screened from the soils of Jaipur, Jodhpur & Jaisalmer districts of Rajasthan. These bacteria showed a temperature range of 40°C to 78°C for their growth. The bacteria isolated from Jaisalmer soil showed amylase positive raction, whereas from Japiur & Jodhpur soil, negative result at a specific temperature. Bacteria isolated from soils of Jaipur, Jodhpur & Jaisalmer showed negative results for catalase test. Bacteria...

In our present research work a mixture of house-hold agricultural wastes were utilize as fermentation medium for solid state fermentation to make the process more economical. In this study, adsorption property of activated charcoal was utilized, which resulted in maximum decolourization along with retention of an appreciable activities for the produced alpha amylase(11261.5280 U/gds) & amyloglucosidase (193.3217 U/gds ) when compared to contro...

Starch is a polysaccharide molecule consisting of a large number of glucose monomer units, joined together by glycosidic linkage. a-amylase is the enzyme, responsible for the breakdown of the glycosidic linkage of starch. Besides the use in starch hydrolysis, a-amylase enzymes are also used in a number of other industrial applications, such as in laundry and in baking industries. The large scale production of this enzyme has boomed in the last...

Removing sulfur from oil streams and necessary design methodology and basics. From reactor design to optimum criteria for every temperature and pressure conditions. Importance of such unit operations to reduce sulfur content and prevent catalyst poisoning. Material balance and energy balance for all pathways. To obtain low sulfur petroleum naphtha with acceptable limits of sulfur. Every equipment specification for a given pathway is considered.

Project Report from the year 2014 in the subject Biology - Micro- and Molecular Biology, , course: Personal Research Project, language: English, abstract: The aim of the present research work was to study a low-cost production of Lactic acid by fermentation of a non-conventional medium e.g. cheese whey, while considering milk medium as a standard using Lactococcus lactics. The effect of different process parameters such as pH of the medium, ...
