The functional capacity of plantaricin-producing Lactobacillus plantarum SF9C and S-layer-carrying Lactobacillus brevis SF9B to withstand gastrointestinal transit

Essay Instructions:

Paper Guidelines: You are required to write an article review on a microbiology-related topic with a minimum of 2 pages of content (in addition to title and reference pages) that will be due on Sunday of Week 7 by 11:59 pm. Students will choose one article from a primary peer-reviewed literature source (e.g. Science, Nature, Journal of Microbiology, Virology, etc.) which uses a microbe as a model organism/system. The article review must follow a format used for scientific review articles. This assignment should be in APA format. It should include a title page, at least a minimum of 2 pages of content in which you have reviewed the content, as specified in the assignment's instructions, and a references page. PLEASE NOTE: NO ABSTRACT IS NEEDED FOR THIS ASSIGNMENT. You should include in-text citations of your sources, as required by APA format. Please be sure to review my prior announcements on this assignment or view the assignment's instructions for further details. A MINIMUM OF 5 REFERENCES ARE REQUIRED FOR THIS ASSIGNMENT, OF THOSE FIVE, ONLY TWO CAN COME FROM THE INTERNET. (Please note that your paper is one of your sources and it is NOT considered to be an internet source - it is a scholarly source from a journal - thus you can use as many scholarly journal articles as you want for references). The review should address the following questions: A. Why did the scientists perform the study (i.e. brief description of background)? B. What was the hypothesis (or hypotheses) under investigation? C. What were the major techniques/results and did they support or negate the hypothesis? D. Why are the results significant and do they point to further/future studies? E. Why did you choose this particular article to review? Was it interesting, informative, clearly written, or none of the above? All credit will be given for your honest opinions. - THIS IS THE ONLY CRITERION IN THE ASSIGNMENT WHERE YOU SHOULD WRITE IN THE FIRST PERSON FOR YOUR PAPER. You MUST also check the Global Reference Database plagiarism detection tool box (Turnitin, AI incorporated) BEFORE you submit your assignment in order for it to be graded. Failure to do so will result in your assignment not being graded and you receiving a 10% late penalty until the assignment has been submitted to the plagiarism detection tool. PLEASE NOTE: Your paper should have no more than 25% similarity (please make sure that your "in text citations" are in your own words or Turnitin will catch it as plagiarized). If your submitted assignment is over the maximum 25% similarity, yet it is ONLY the REFERENCES/SOURCE SECTION of your paper that is highlighted in the Similarity Report, YOU DO NOT HAVE TO RESUBMIT IT OR EMAIL ME, as that will NOT be counted against you or seen as plagiarism. Evidence of plagiarism is when you have a high similarity index that shows large portions of the BODY OF YOUR PAPER as being highlighted.

Article Review Paper Student’s Name Institution Course # and Name Professor’s Name Submission Date Study Background Different ecological niches have lactobacillus strains in their food chains, and each of these microbial strains is in constant competition for space and nutrients. The scientists highlight the importance of lactobacillus strains in microbe communities such as those found in sauerkraut fermentation. Bacteriocin-producing lactobacillus possess a competitive advantage in the context of food preservation and probiotic activity. The study by Butorac et al. (2020) borrows previous findings involving spontaneous fermentation studies that were focused on lactobacillus brevis and lactobacillus plantarum. Notably, Lb. Brevis SF9B and Lb. Plantarum SF9C was isolated from these fermentations, with SF9B exhibiting functional properties attributed to its surface-layer proteins (Slps). These proteins were found to play crucial roles in survival in the gut environment, adhesion to host cells, and antimicrobial activity. Scientific studies are meant to inform the current healthcare practices for a better future. Rats were used in these experiments to mimic the actual environmental conditions these microbes will be exposed to in a normal human body. Building upon these previous findings, the study aims to investigate the competitive advantage potential of Lb. Brevis SF9B and Lb plantarum SF9C against pathogens through in vivo and in vitro investigations. This includes evaluating the bacteriocinogenic potential of SF9C against Gram-positive pathogens, as well as assessing antagonistic activity against Gram-negative pathogens. Additionally, the study seeks to explore the colonization potential of SF9C and SF9B strains and their impact on microbiome alterations in rats, particularly in the context of microbiota disturbance induced by AlCl3 exposure. The human body is home to numerous microorganisms, and the bacteria can be classified as either gram-positive or gram-negative (Cleveland Clinic, 2024). In vitro and in vivo investigations will analyze the competitive advantage that these lactobacillus microbes have over other pathogens. Study Hypothesis Lactobacillus strains would withstand harsh conditions in the gastrointestinal tract to exhibit probiotic properties, antimicrobial activity, and neuroprotective function. Main Results The study used a variety of techniques to investigate the probiotic properties and therapeutic effects of lactobacillus plantarum SF9C and lactobacillus brevis SF9B. Polymerase chain reaction gave a positive result for...
