identifying bacteria. Other staining techniques such as Acid Fast stain are also useful in determining species. More important in identification of a genus and species of bacteria are biological tests‚ including the determination of the types of nutrients a cell can use‚ the products of its metabolism‚ and the response to specific chemicals. Other factors that can assist in identification of bacteria are their ecological habitats and more advanced methods such as genetic and molecular composition

root ’s axis. The flesh can be chalk-white or yellowish. Cassava roots are very rich in starch‚ and contain significant amounts of calcium (50 mg/100g)‚ phosphorus (40 mg/100g) and vitamin C (25 mg/100g). However‚ they are poor in protein and other nutrients. In contrast‚ cassava leaves are a good source of protein‚ and are rich in the amino acid lysine‚ though deficient in methionine and possibly tryptophan. These components are components of biodegradable plastic. (http://www.studymode.com)

methods of population estimation November 18‚ 2014 BIOL 1121: General Biology II Lab Fall 2014 Abstract Mark and recapture is a method commonly used in ecology to estimate an animal population ’s size. A portion of the population is captured‚ marked‚ and released. This lab provides methods that can be used to estimate a provided additional information for a better interpretation of lichen diversity values in biomonitoring studies of air pollution.

Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The

We will be using a method called Polymerase Chain Reaction (PCR) to amplify the 16S rRNA gene present in all prokaryotic cellular life and also culturing samples onto an agar plate for visual identification. This will allow for the accessibility of comparing the similarity or differences in the DNA sequence‚ which can reveal close/distant connection between various bacterial species in the American River community based
