Contaminant profiles were related to surrounding land-use. Temporal trends are poorly defined while chemical loadings followed rainfall levels. Abstract The Lower Columbia River in Oregon and Washington, USA, is an important resource for aquatic and terrestrial organisms, agriculture, and commerce. Keywords.

Irp 3 cell respiration. Living Factories. Microbiology Lab : MOLB 2210. Tests used to identify Gram Positive Bacteria Tests used to identify Gram Negative Bacteria Mannitol Salt Agar (MSA) This type of medium is both selective and differential.
The MSA will select for organisms such as Staphylococcus species which can live in areas of high salt concentration (plate on the left in the picture below). This is in contrast to Streptococcus species, whose growth is selected against by this high salt agar (plate on the right in the picture below). Glucose broth with Durham tubes This is a differential medium.
Blood Agar Plates (BAP) This is a differential medium. What type of hemolysis is seen on each one of the following plates? Streak-stab technique Often when inoculating a BAP to observe hemoloysis patterns, investigators will also stab several times through the agar using an inoculating loop. Bile Esculin Agar This is a medium that is both selective and differential. Sulfur Indole Motility Media (SIM) This is a differential medium. Kliger’s Iron Agar (KIA) CAMP Test.

To find the ability of microorganisms to ferment the given Carbohydrate.
To determine the ability to degrade amino acids. To determine the ability of microorganism to produce gaseous end products in fermentation. A metabolic process performed by almost all types of bacteria is known as fermentation. This will result in the production of ATP, the ultimate energy source of the organism. This will happen either in the presence or absence of atmospheric oxygen. Lab - General Biology. Biology 211 Labs.
