Introduction: The effectiveness of Antimicrobial agents against Microorganisms Population of microorganisms or growth are killed and/or inhibited by natural or synthetic chemical antimicrobial controls (Madigan, et al 2012). Antimicrobial agents are grouped according to their efficacy against microorganisms. Bactericidal that kill and bacteriostatic prevent and/or reduce growth (Madigan et al, 2012). Harmful pathogens are targeted with different antimicrobial agents according to their toxicity…

The purpose of the research was to potentially find a new bacteria that is capable of producing an antibiotic against one or more of the six ESKAPE pathogens (a group of pathogens that are resistant to most if not all current antibiotics). All research protocol was based on the Yale Small World Initiative and the third edition of Microbiology Laboratory Theory & Application. One bacteria from a sample of soil collected (colony #18) was tested for its ability to produce antibiotics against two of…

This rod-shaped bacterium is gram negative which makes it a facultative anaerobe which grew perfectly in 37-degree temperature. This species was motile and therefore it can synthesize an enzyme known as ornithine decarboxylase. This bacterium is prevalent in the intestines of animals…

Abstract: This experiment was meant to look and find gene linkages and determine the crosses of the tan x wild type (black), gray x wild type (black), and tan x gray spores of the Sordaria fimicola. To accomplish the crossing, the plates filled with auger had to be set up with each individual kind of spore. Three plates with two different spore colors of sordaria in each. One plate was black and tan, black and gray, and gray and tan. For gene to centromere distance the standard deviation was…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…
