The iodine in this staining technique is used after the crystal violet is applied. The iodine then affixes this and then a decolorizer is applied to take away the primary stain. Why is it important to heat fix the bacteria prior to the staining procedure? It is

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

During my senior year of high school I applied to Millersville University to pursue a Bachelor of Science in Biology‚ with a concentration in marine biology. Through my undergraduate studies‚ my interest in biological oceanography developed. There are many overlapping aspects of biological oceanography and marine biology that interest me and why I want to pursue a graduate degree in this field. I am particularly interested in marine phytoplankton‚ their role in primary productivity‚ harmful algal

Stem Cell Research Adult stem cell research is providing opportunities to treat people with a various diseases and conditions. In 2010‚ a man’s ankle refused to heal so the doctor took bone marrow from the man’s pelvic bone with a needle‚ condensed it to about four teaspoons of rich red liquid‚ and injected that into his ankle. Four months later‚ the ankle was healed! Adult stem cells are found in all tissues of the growing human being and‚ according to latest reports‚ also have the potential
