We suggest that culture 16 is an example of Escherichia coli. Background: Techniques used were in accordance with NMU Professor Dr. D. Becker’s lab manual (ISBN 0-390-53911- 2; McGraw Hill). Changes in protocol or interpretation are noted where they were implemented‚ but strict adherence to the manual

observed the granules in the microscope as highly refractive inclusions. However‚ the first example of PHA came in existence until almost four decades later in 1926 when a French microbiologist Maurice Lemoigne discovered that a gram negative bacterium Bacillus megaterium accumulated intracellular granules of a polyester called polyhydroxy-3-butyrate (PHB) (Amara et al.‚ 2011). PHA accumulation ability has been reported for many microorganisms including Gram-negative and Gram-positive species (i.e. autotrophic

The steaks that were done on this plate seemed to show that E. coli did not have lipases because it did not have clear zones. Staphylococcus aureus seemed to have these clear zones meaning it can secrete lipases. The bacteria Bacillus subtilis did not grow well to see if there was a clearing. After doing some research‚ it was shown that B. subtilis is lipase positive so there should have also been some clear sones like the Staphylococcus aureus (Watson). The DNAse agar could not

2.4 Mechanism Of Phosphate Solubilization: In contrary to Nitrogen soluble Phosphorous is not supplied to plants by atmosphere . Due to this reason the primary and secondary minerals and/or organic compounds are the source of P to great extent. In soil solution concentration of phosphorous is least as compare to other nutrients and ranges from0.001 to 1mg/ml Brady and Weil (2002 ).There are widely three categories of P compounds in soil: (i) compounds which are inorganic‚ (ii) organic compounds

Bacterial Smears Are Fixed before Staining to? Answer It is important to heat fix the bacterial smear before staining so as to‚ kill the bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without
