Micro lab report 1 Blood and Bacteria Essay

The colonies were smooth, translucent, and had a white brownish color. The Gram stain resulted in Gram positive cocci. After the Gram stain was completed, the bacteria were streaked on a Mannitol-Salt Agar plate and a Catalase test was performed. After these test were completed a Phenol Red Dextrose Fermentation tube was inoculated, and a SIM Tube inoculated.

4. Compare and contrast the structure of a fungal mycelium with the structure of a filamentous alga.

They occur as single bacterium, which uses the names cocci, bacillus, spirillum, vibros. They occur as pairs, which add the prefix diplo, such as diplococci. They appear as linked chains, with the prefix strepto, as in streptobacillus, and they occur in clusters with the prefix staphlo, as an example, staphylococci.

Purpose: The purpose behind this unknown project is to help us determine the identity of the liquid culture we have selected. With the freedom we’ve been granted, we are permitted to use any of the tests that we have performed in our previous labs to assist us with identifying the organism. This project is intended to push us to use the knowledge we have acquired, using proper staining techniques and thorough understanding of testing techniques and results to draw conclusions.

Plate B incubated at 25oC produced a white, opaque, waxy, and spreading bacteria colonies while plate A incubated at 37oC produced a white, thin spreading bacteria colonies (Figure 1.). Gram staining revealed that plate B contained a rod-shaped bacterium having partial pink and purple coloration with endospores. This suggests that the bacteria is a gram positive bacteria. Gram positive bacteria typically have a thick cell wall which traps the crystal violet making them appear purple. Conversely, plate A is a rod-shaped bacterium but with pink coloration.

The shape of the S. aureus is a Gram-positive spherical bacterium that occurs in grape like clusters, which are golden. The golden color is the result of a carotenoid pigment that protects the bacteria against host-immune system reactive oxygen species, and adds to the bacteria's virulence. Staphylococcus aureus is a gram-positive bacterium, which means that the cell wall of these bacteria consists of a very thick peptidoglycan layer. Whereas NM is a gram-negative, coffee bean shaped aerobe bacterium. The bacterium

The bacteria cell looks like a pill capsule with a long tail called a flagella. Attached to the outside of the capsule like cell are spaghetti like pili. Around the cell is a cell wall. The cell wall, capsule cytoplasmic membrane are all like a wall around the cell. The Ribosomes are like a bunch of tiny little dots within the cell wall. In the middle of the cell is the nucleoid. The cytoplasm is a jell like structure contain of the cells interior parts. The nucleoid is scattered strands of DNA. I looks a lot like pieces of hair woven

Streptococcus pyogenes is categorized on the origin of colony morphology, hemolysis, and biochemical reactions. .Streptococcus pyogenes is a sphere-shaped bacterium or cocci that appear in chain-like constructions. It stains purple when the Gram stain system is used. This indicates that S.pyogenes is a gram positive bacterium. When the bacterium is grown on agar with sheep blood, it appears as a glowing colony with a region of hemolysis surrounding the colony. This is a result to the precise enzymes that are produced by Streptococcus pyogenes. S.

Macroscopically spore surfaces are usually smooth with downy to wooly texture. It has a light gray to olive brown on its surface and can become covered aerial hyphae that are short and gray.

The genus of Pseudonocardia suggested for mycolate-less and nocardioform actinomycetes that had a type IV cell wall. Members of this genus have no motility and their aerial mycelium section to shape chains of straight or zigzag spores. The organisms contain MK-8 (H%) as the main monoquinone and iso-branched hexadecanoic acid as the major fatty acid. The pattern of phospholipids is either type pII or pIII.

We can see the tornadoes thanks to the dust sucked upwards and the condensed drops of

Bacteria cells are classified according to their size, shape, the compounds they digest, and in some cases their gram stain. There is some bacterium, that the only differentiating factor is the size of the bacterium. In the case of these bacterium, it is important to be able to identify them to determine their possible effects in their environment. This is especially true in the medical world, with many conditions caused by an influx of infectious bacteria. An accurate identification of the bacteria is required to determine the proper course of treatment.

Size, small to medium; shape, dorsoventrally flattened, typically rigid, oval to rectangular; freeswimming; alveoli well-developed and, at least in euplotids, filled with a protein, called platein; somatic ciliature commonly represented by rows or localized groups of polykinetids, called cirri, conspicuous on the ventral surface; dorsally, files of widely spaced dikinetids with short cilia (“sensory bristles”) and retention of a laterallydirected kinetodesmal fibril ; files of marginal cirri, incomplete or absent; somatic infraciliature typically retained during encystment ; prominent adoral zone of generally numerous oral polykinetids, as paramembranelles, on left-anterior portion of the ventral surface, bordering a broad, non-ciliated peristomial field and sometimes continuing over apical end of body onto the dorsal surface; paroral as paroral and/or endoral in diploor polystichomonad condition; stomatogenesis, generally apokinetal, beginning in a cortical pocket in some forms, but sometimes parakinetal; macronucleus, ellipsoid to band-shaped or in fragments, with replication bands moving from ends to middle when the nucleus is elongated; micronucleus, one to several; conjugation, temporary; contractile vacuole, at least present in freshwater forms; cytoproct, present; microphagous and macrophagous; in marine, freshwater, and terrestrial habitats, widely distributed as free-living forms, but a few species as ectocommensals on various invertebrates and one inquilinic in an echinoid; two orders.

Bacteria vary greatly in terms of their characteristics and morphology. Colonies can be classified according to their colour, form, elevation, margin and size. Pure cultures of microorganisms
