The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

rest of the solutes are covalent bonds. Iodine and paraffin are both non polar molecules. This can be shown by the eletronegativity difference‚ and the shapes the molecules make‚ which show that they are very balanced molecules. Sugar‚ citric acid‚ urea‚ and borax‚ are all polar bonds. This is known because they have a bigger electronegativity difference than non polar‚ but smaller than ionic bonds. Also‚ the shapes of the molecules show the

Week #1 -autotrophs are organisms that harvest light or chemical energy in organic compounds. They self nutrition -heterotrophs are organisms that get complex nutrients from the environment (by eating other organisms) -Fungi are heterotrophs or predators because they are parasitic. Bread mold secretes digestive enzymes to enter the membrane. Same as foot fungus‚ it extends hyphae (fungal branches) into the cells to absorbs nutrients -One fungus makes traps for nematode worms while another fungus

INTRODUCTION Many infectious diseases caused by infectious agents‚ including bacteria‚ fungi‚ viruses and parasites‚ have plagued human existence CITATION Kon97 \l 1033 (Koneman‚ 1997). Thus the identification of bacteria becomes all the more important in the search for medicines and cure. Identification of bacteria is a multistep process because while some preliminary guesses can be made from the morphology of microbes on various differential agars‚ various other tests need to be done to differentiate
