Whilst foods such as ‘meat’ form relatively well -defined groups of raw materials‚ ‘fish’ constitutes a large range of types (some sources recognise over 20‚000 identified species)‚ caught over

economical project. In this we want to show how to reduce the harmful effects of nitrogen which gets mixed with water by natural hazard or else by man-made hazards. With the help of two types of bacteria like thiobascillus and rod shaped bacteria of bacillus species‚ we want to reduce the adverse effects of the dissolved nitrogen in the water bodies. HYPOTHESIS:- Nitrate-rich water containing denitrifying bacteria will exhibit a faster rate of reduction in nitrate levels. OBJECTIVE:- To denitrify

DEBATE REGARDING GENETICALLY MODIFIED CROPS INTRODUCTION:- For thousands of years‚ human beings have modified nature’s organisms for usage in agriculture. New technology has furthered this trend: recombinant DNA technology allows biotechnology firms to insert DNAs into plant genomes‚ thereby creating plants that express the desired traits. Use of such genetically modified organisms (GMOs) has prompted controversy‚ especially for its role in ensuring food security. As such‚ the use of

Unknown Lab Report Unknown Organism #6 Ann Le (Phuoc) May 6‚ 2010 Dr. Carrington Microbiology Lab- MW 12:50 Le 1 I. Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

History of Medicine as well as Medical technology in Japan The most interesting features of Japanese medicine‚ including Japanese Medical Technology are the extent to which it was derivative and the rapidity with which‚ after a slow start‚ it became Westernized and scientific. In early times disease was regarded as sent by the gods or produced by the influence of evil spirits. Treatment and prevention were based largely on religious practices‚ such as prayers‚ incantations‚ and exorcism; at a later

used in the experiment is Aspergillus oryzae and Bacillus licheniformis. B. lichenformis is classified as bacteria that can be seen in soil‚ and is usually transported through a bird’s feathers or plumage. A. oryzae is a type of mold‚ or fungi‚ that is utilized for Asian food production‚ which could include the fermentation of soybeans. The student is required to discover the optimal temperatures for both‚ Aspergillus oryzae (Fungal) and Bacillus licheniformis (bacteria). For this case‚ the student

Examples of transgenic species are commercial crops‚ such as corn‚ potatoes and cotton that contain the gene for the toxin from the bacterium B. thuringiensis. This toxin protects the crops against damaging pests however does not harm their natural predators. Recent work has involved the production of transgenic cows and goats. The cloned transgenic goats Mira‚ Mira and Mira produce milk that contains

These were treated with Bacillus pumilus and Variovorax paradoxus under water and salt water (100mM‚ NaCl) conditions. 14 seeds were treated for each sample data set‚ but not all germinated. The sections where no results are shown‚ was due to dehydration of the petri dishes. Standard
