Clostridium sporogenes; an obligate anaerobe. During an infection, large amount of gas accumulates in the infected tissue. Would you expect this gas to be CO2? Explain?
2. You are given a mixed broth culture of Pseudomonas fluorescence (Gram-negative) and Clostridium sporogenes (Gram-positive). You are instructed to isolate and purify each bacterial species. How are you going to do it? Your goal is to have a plate of pure P. fluorescence with isolated colonies and a plate of pure C. sporogenes with isolated colonies. Explain in detail how you are going to perform the exercise. You can use any media you like such as nutrient agar plate,...
1. Draw a graph of growth rate vs temperature for a mesophile. 2. Why do halophiles produce compatible solutes?
the bacteria Clostridium botulinum and Clostridium perfringens cause such severe food poisonings that commonly result in death. You are given a food sample that might contain these bacteria. name the staining procedure you would conduct, the dyes used, and describe what you would see on the slide you prepare if one of these species were present.
1. Please give the name of the exotoxins associated with the following bacteria? a. Clostridium tetani b. Clostridium perfringens c. Clostridium botulinum d. Clostridium difficile e. Bacillus cereus f. Corynebacterium diphtheriae g. Corynebacterium ulcerans a. Clostridium tetani b. Clostridium perfringens c. Clostridium botulinum d. Clostridium difficile e. Bacillus cereus f. Corynebacterium diphtheriae g. Corynebacterium ulcerans 2. Which of the above require that a bacteriophage must be inside.
whats the relationship between toxoids and clostridium tetani and botulinum?
The microbial production of 1-butanol utilizes various species of Clostridium, particularly acetobutylicum. Clostridium acetobutylicum is a Gram-positive anaerobe which also produces byproducts such as butyrate, acetone, and ethanol. As a result, its 1-butanol yield is difficult to control. Its relatively slow growth rate and spore-forming life cycle create additional problems for industrial fermentation. Furthermore, the relatively unknown genetic system and complex physiology of the microorganism present difficulties in engineering its metabolism for optimal production of 1-butanol. Therefore, there is strong...
