Bacillus subtilis

main error was in the second plate where no results could be found for any of the four sections. As can be seen in the photo a small amount of culture did grow around part of the edge of the dish. This means that the error was not due to no Bacillus Subtilis being added to the pour plate. The error could possibly have been not swirling the plate after the agar was poured which would mean…

presence. IV. To learn how to know whether the culture is a selective or differential media. The culture bacteria that will be using are E. coli, Bacillus subtilis, staphylococcus aureus and Proteus vulgaris. V. To learn how to find the extracellular enzyme production by bacteria. The culture bacteria that will be using are E. coli, Bacillus subtilis, and staphylococcus aureus. Result i. The two…

not able to bind and the second dye is observed. Some known Gram-positive genera are Bacillus,…

Gram-negative (fig. 3) due to displaying a predominately red color. Bacteria B was found to be Gram-positive (fig. 4) due to displaying a dominate blue color. Bacteria B was also noticeably a rod, or bacillus, shape which helped to further narrow down the possibilities to two bacteria: Bacillus cereus, and Bacillus…

was made in vitro for compounds which showed antimicrobial activity. Compound 3b has broad spectrum activity against Gram +ve bacteria, Gram -ve bacteria, Yeast and Filamentous Fungus with MICs 150, 150, 75, 312, 625 and 625 µg/mL against (Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 3555, Escherichia coli ATCC 23282 Pseudomonas aeruginosa ATCC 10145, Candida albicans IMRU…

structure are different from the other peroxidases classifications; this can is demonstrated by the ability of this peroxidase to degrade anthraquinone-dyes (Reactive Blue19). Other result showed was the comparison of the specific activity of the Bacillus subtillis peroxidase with the peroxidase of other microorganisms and the results this study was between the results of the other studies. The specific activity of B. subtillis peroxidase was higher than from Thermobifida fusca and lower than…

1. The biggest potential source of contamination of the locations we tested in the Distribution of Microorganisms would have to be the floor of the lab. The reason why this is the biggest potential source of contamination is because multiple people are coming in everyday from the outside world, bringing in microorganisms from the outside into the lab. And although we sanitize the counter and all the spaces that we work around, we don’t take precautions to necessarily clean the floor, making it…

Bacteria also known as prokaryotes are very ancient single-celled organisms; fossils show that they were widespread 1.5 billion years ago. Today bacteria make up the vast majority of prokaryotes on earth due to the unfavorable ability to adapt quickly to the surrounding environment. Bacteria have the capabilities to survive in areas of high heat, extreme cold, or even very acidic or alkaline conditions. This ability is used frequently to fend off the effects of antibiotics and antibacterial;…

1.2 Fungal Plant Pathogens For centuries, Canadian farmers have lost their crops to disease caused by fungal plant pathogens. In agriculture, crop contamination is detected in both pre- and postharvest stages of growth (Bonaterra et al., 2003). During preharvest field preparation, the objective is for farmers to mitigate the negative impacts on biodiversity, improve forest production and minimize impacts on the residual forest stand, soil and water values (Chung et al., 2008). The current use…

against the dracaena leaf spot fungi. The in vitro assays conducted showed that the bacterial biocontrol agents namely, Stenotrophomonas maltophilia, Pseudomonas ultimum, Pseudomonas fluorescens, Pseudomonas putida, Pseudomonas aeruginosa, Bacillus subtilis, Bacillus megaterium, significantly decreased colony growth diameter (76.84%-45.69%) of dracaena leaf spot fungi as well as spore…
