Genus

contains pertinent information. By using the lab notebook with systematized exercises’ results, one categorized the environmental isolate’s characteristics by morphological, physiological, and biochemical characteristics which allowed one to identify the genus of this…

This genus of bacteria is known to be aerobic, gram-positive, non-motile bacteria. With shapes within colonies varying from rods to cocci (Finnetry 1992). This general knowledge backs up the conclusion and identification of the bacteria cultured in this study. Rhodococci are known to be widely spread throughout soil and sludge (Finnetry 1992) making the discovery of this genus in the tested sample a common find. Infections from this genus of bacteria have increased over…

morphological changes in horse from the Eocene epoch to the Holocene epoch and determine how these changes in characteristics may have a paralleled relation to the species’ environment. Eocene epoch lasted from 55 to 45 million years ago. The horse genus at that time was Hyracotherium, relatively small in size with a…

of cartilage instead of bone. That is, cartilaginous fish such as tiger shark has a very rapid regrowth of lost tissue or whole body parts of their endoskeleton. Tiger shark belonging to the genus Galeocerdo. The genus has lived since the Eocene period, which lasted for about 56-34 million years ago. The genus has always consisted of 11 species, but it is only the modern tiger shark (Galeocerdo Cuvier) that lives on today, making it alone in the race. Unfortunately, we know not so much about…

A sputum sample can be collected and some key tests that help identify just the genus Streptococcus includes: gram staining, mobility tests, oxidative-fermentative tests and endospore tests. The other tests that help identify the species include: capsule tests, catalase tests, hemolysis tests and pyrrolidonearylamidase tests. (2). The genus Streptococcus is a, gram-positive cocci which ferments sugar, but the final product will always be lactic acid (2). Streptococcus…

desired rye or some other species of either grains or wild grasses, it uses the plant as a host in the process of replacing the host’s reproductive organs with a sclerotium, which is created differently for each Claviceps sp. Speaking of species, the genus Claviceps have been narrowed down to sixteen species through RNA-declassifying phylogenetic trees, which Sylvie Pažoutová kindly states in the following: C. paspali, C. zizaniae, C. grohii, C. sulcata, C. fusiformis, and C. purpurea, C.…

flatter tail could help the male on land or in the water. Janzen, Brossman, Arntzen, and Gvodik all either discuss the tails themselves or experiment with the tails of newts and their significances. Halliday’s work also goes into depth of another Genus of newt that has very different mating rituals than Taricha, and I am hoping to get another perspective of how a tail could benefit one newt over…

Diatoms are considered as one of the critical biostratigraphic tools, especially where calcareous fossils are absent or poorly preserved. While diatoms were common both in marine and non-marine paleoenvironment, diatom-based biostratigraphy is widely used in the marine stratigraphic record. Multiple Deep Sea Drilling Projects (DSDPs) made the core samples available from Antarctic, Equatorial Pacific, and High Latitude North Pacific region. The earliest known fossil diatoms are from Lower…

Phylogeny of Sphyrna- Hammerhead Sharks INTRODUCTION I will be investigating the phylogenetic history of Sphyrna, a genus of hammerhead sharks. The eight species that fall under this genus are Sphyrna corona (scalloped bonnethead), Sphyrna gilberti (Carolina hammerhead), Sphyrna lewini (scalloped hammerhead), Sphyrna media (scoophead), Sphyrna mokarran (great hammerhead), Sphyrna tiburo (bonnethead), Sphyrna tudes (smalleye hammerhead), and Sphyrna zygaena (smooth hammerhead). Hammerhead sharks…

Collection and Identification of an Environmental Bacteria to the Genus level Introduction: Bacteria can be found virtually anywhere, and interaction with these organisms occurs daily (Fitzpatrick & Allison, 2014). However, though the interaction between human and bacterium is continual, it is not always known what type of bacteria a person is coming into contact with. Therefore it is important to understand, and to have knowledge about, the characteristics of bacteria in our environment. As…
