be either organic‚ meaning from a living organism‚ or inorganic‚ such as carbon dioxide. Prokaryotes split into two lineages known as Archae and Bacteria. The Bacteria are more numerous than the Archae. Bacteria can be endospore-forming bacteria. Bacteria that form endospores are able to survive harsh and severe conditions. Bacteria can also be Enteric Bacteria‚ they inhabit the intestinal tracts of animals. One species is

Aseptic Technique and Culturing Microbes‚ Lab #3 Purpose: The purpose of the this experiment is to learn to transfer microorganisms to a nutrient medium to promote growth using aseptic techniques. which are a method used to prevent unwanted organisms from contaminating a medium. We will also learn about different types of culture media‚ including MRS broth and nutrient broth‚ learn about oxygen and temperature requirements for microbial growth and how to control microbial growth. Procedure:

Aseptic Technique and Culturing Microbes Lab 3 Brittney Case August 4th 2013 Section: Mic 101 Microbiology Session 1 Abstract: The Purpose of this experiment is to gain knowledge of how to properly use aseptic techniques to transfer cultures‚ learning about cultured media and how to distinguish various types of microbial growths as well as what is required for them to grow properly. Hypothesis: This exercise will allow me to gain knowledge of how to properly use aseptic techniques

Morales‚ Marinel M. Dr. Annie Cu Gallardo BSE-Biological Sciences III-3 Microbiology (Lecture) Microbiology Written Report REPORT NO. 1 Prokaryotes: Bacteria Most of us have been conditioned to think of bacteria as invisible‚ potentially harmful little creatures. Actually‚ relatively few species of bacteria cause disease in humans‚ animals‚ plants‚ or any other organisms. In fact‚ all organisms made up of eukaryotic cells probably evolved from bacteria-like organisms‚ which were some

Class‚ Euascomycetes; Order‚ Onygenales; Family Onygenaceae; and the Genus Coccidioides. Coccidioides immitis are thermally dimorphic fungus that reproduces by arhroconidia‚ swelling of arhroconidia in vivo into spherules (which burst and release endospores.) The fungi is found mainly in warm dry areas with low rain fall‚ high summer temperatures‚ and low altitude. C. immitis is geographically limited to the san Joaquin valley region‚ and co exists with C. Posadasii in the desert southwest of the United

I. INTRODUCTION Independent Study Questions 1.) What is the fundamental difference between eukaryotic and prokaryotic cells? Procaryotic cells do not contain a membrane-bound nucleus or any membrane-bound organelles. Eurkaryotic cells contain both a membrane mound nucleus and membrane-bound organelles (making them far more complex). 2.) List and describe the two domains of prokaryotic organisms. a. Bacteria- Most are a specific shape (cylindrical‚ spiral‚ or spherical). Cell

cereus‚ a soil bacterium‚ and B. anthracis‚ the cause of anthrax: the three organisms differ mainly in their plasmids. Zakharyan R.A et al. first reported the presence of plasmids in B. thuringiensis and suggested involvement of the plasmids in endospore/crystal formation. They also described the presence of large plasmid in the Cry+ variant of B. thuringiensis Upon sporulation‚ B. thuringiensis forms crystals of proteinaceous insecticidal δ-endotoxins (Cry toxins) which are encoded by cry genes
