Food Microbiology – ONPS1042


ASSIGNMENT 1 – written communication task


Literature review

Each student submit their own literature review. Write a section on each of the following chemicals used for microbial preservation of food. Chemicals to be covered should include:  x Nitrite/nitrate

x sulphur dioxide

x introduce the use of organic acids including sorbic, benzoic, propionic acid and the parabens BUT THEN concentrate your writing in this section on sorbic or benzoic acid

x the use of an organic acid as a surface spray or dip


(please do not review plant derived products such as essential oils from herbs and spices, animal derived products such as lysozyme and lactoferrin and the microbial metabolites bacteriocins and hydrogen peroxide as we will discuss these in lectures).


Criteria for content In your review for each section you should cover the following information:

x The action of the chemical on microbes to kill them (ie their antimicrobial effect).

x The types of microorganisms that are sensitive / resistant to the chemical and the reasons for their specific resistance or sensitivity. Include both spoilage and pathogenic microorganisms.

x The types of foods that use the chemical as an ingredient in formulation and why these food groups choose to use the chemical.

x Safety restrictions on the chemicals use and reasons for restrictions.

x Dose allowed in food (see additives and processing aids in the Food Standards Code of FSANZ web site or EU recommendations or FDA recommendations – AND ENSURE YOU REFERENCE WHICH STANDARDS YOU ARE QUOTING).

Background reading: Adams and Moss Chapter 4.5.

Contents page: An index or contents page should also be included.

Length Literature review should be 1500words (+/- 10%). (hint – put some information in tables to decrease word count as it is not included in the word count), The table and any reference are not included in the word count.

Guidelines Writing of the literature review should be based on Guidelines for a Literature Review. (this document is in online assignment section).

Written font and paragraph format Please use Times New Roman, 10 pt, and double spaced. When using acronyms ensure you first used the full title then the acronym in bracket and then you can use the acronym only for the rest of the report – eg “ the product was made using Good Manufacturing Practice(GMP). There are a number of support systems that are included in a GMP program”.

Tables and figures: Collating some of the information relating to the criteria for content (above) into tables and using figures is encouraged. Tables and figures do not count towards the word count. With a simple explanation in the text referring to what the table is interpreting they are very good for a literature review like this. In particular tables would allow you to set out specific information on efficacy of preservation with respect to a range of organisms and also across different food groups. Ensure your title for tables is above the table and figure title is below the figure. If you copy or modify tables or figures from an article / book ensure you reference them correctly. Use your own numbers either fig1 to eg 10 – or Fig 1.1, 2.1 etc for chapters or subsections. Make sure you explain the relevance of each figure / table in the text.

Word count: 1500 words +-10%. Please register a word count on the front page when you submit your assignment. Go to Tools / Word Count. Do not include contents page, tables, figures and references in the count.


There must be at least 12 references (at least 5 in the last 10 years and definitely not just review books). See Guidelines for Literature Review and Referencing in the online assignment section for details.

Reference formatting: Please use the APA referencing system for citing references in text and reference section;ID=8rwjnkcmfoeez Your . For journal abbreviations go to:

Plagiarism and Turnitin

The review must be submitted via Turnitin in the assignment 1 section of your Blackboard ONPS1042 site. This checks for plagiarised material. Please refer to the document in the online assignment section for details of how to do this.

Your assignment must be <10% similarity index and there should not be any major block of similarity more than 2%. You may submit your review as many times as you like before the final date of submission to Turnitin date ie 24 hours before the close date and time for submission, to check you are not plagiarising but after the final close date and time you cannot resubmit. Please see timetable for relevant dates. Please also read the details of academic integrity and plagiarism at All support information for staff and students is at: Submission for marking Literature review draft – new students in their first semester ONLY can show me a hard copy draft at least 1-2 weeks before final submission. You must submit a hard copy of the final assignment, including the cover sheet and a copy of the turnitin % originality report of your final draft, to reception building 3 level 1 city campus by the due date as requested in the timetable for this course. The cover sheet is at Help with English expression: If your English expression is poor, please get a peer to read the report and help you with any English expression changes and spelling etc BEFORE YOU HAND IT IN or the seek help from RMIT English Worldwide. Things not to do Books like Hocking and Doyle are already literature reviews. Using these extensively for referencing is not a good literature review and will receive low marks – however there are lots of references linked to the chapters in those book that can be searched and referenced if read and used in the review. Do not use references within a chapter or book unless you have sourced the reference. Marks will be allocated in the following categories: 1. Literature review directly related to the topic criteria and directly related to food microbiology and micro-organisms. (see Content criteria dot points above) 2. A GOOD review of the literature – not just a rewrite of the most used references or an already written review. Use you own headings to design content and incorporate material from all the literature you have written. Extra marks will be given to people who think critically about the information they are incorporating and who include a critical comparison of information from their literature search in their literature review. 3. All references used correctly cited in the text and all those cited in the text written in the reference section in correct format in alphabetical order, preferably in APA format. If you have not used APA format please add a copy of an example of a reference format you have used. 4. Accuracy in microbiological terms eg microbiological organisms names in italics and properly spelled. 5. Tables and figures correctly used and numbered, with titles relevant to what you are writing about, and properly explained in the text. 6. Plagiarisms of heading and paragraphs from text will not be tolerated. If students plagiarise they will receive zero for the assignment. For more details please read: GUIDELINES FOR LITERATURE REVIEW AND REFERENCING.

  1. Ebony (black body, b) and apterous (vestigial wings, v) are recessive traits, present on different chromosomes. A cross is performed between an ebony female with normal wings and an apterous male with normal body color.
  1. What are the genotypes of the parental flies? (10 points)
  1. List the genotype(s) and phenotype(s) you expect to see in the F1 offspring. Explain how you arrived at your answer. (10 points)


  1. A cross is performed between an ebony female fly and a sepia (brown eyes; s) male fly. Ebony and sepia are recessive traits. All of the F1 offspring are wild-type.
  1. What are the genotypes of the parental and F1 flies? (10 points)

The F1 flies are crossed, and the following results are obtained:

48 wild-type body color and eyes

26 ebony, wild-type eyes

24 wild-type body color, sepia

2 ebony, sepia

  1. Is this result expected for traits that are not linked? Explain. (10 points)

Cloning, Genetically Modified Foods, or Bioethics

“Cloning, Genetically Modified Foods, or Bioethics”

Because BIOLOGY is an essential element of our everyday lives, we see and hear news reports on a variety of issues that relate to it almost every day. Your assignment is to research and review one article or report on the specified topic or issue related to Biology indicated. Additional information on writing a journal (or newspaper) review or summary can be found in the attachments to these instructions. Your report should be organized as follows:

Title of the article or report pertaining to the specific topic for the week
Author of article
Source of article or report (This includes the name of periodical, newspaper, or other media resource. Include the “URL” for online resources. “Wikipedia,” other encyclopedias, and textbooks are not approved sources. The source must be valid, as I will check the source)
Date of article (this is absolutely required)
“Your summary” in “your own” 200 words or less discussing and/or explaining what the article is about.
Make sure you read the attached files on “Writing a Journal Review” and “Writing Summaries.”
Write an objective summary of the facts presented in the article; therefore, do not use first or second person in your summary. In this summary you are to
discuss (consider as many important elements related to the issue as you can)
explain (tell about something that is complex in a way that makes it clear)
Since the summary should be “in your own words,” avoid directly quoting material from the article, unless absolutely necessary to characterize what the article is about. Also, be mindful of plagiarism.

While it is important for you to demonstrate that you understand the ideas contained in the article, this is not the place for personal commentary. I have tried to align assignments and discussion topics with the chapters covered in the textbook. So an ideal place to share personal commentary on an article that you have read would be the Discussion forums.

The article submitted for the week must be on the specified biology topic or issue listed for the week. The article should come from a source that provides “new” information; therefore, it should not simply define the topic or provide background information that has long been established. See the “Helpful Resources” menu for some websites that offer current biology news articles. The publication date of the article MUST be CURRENT or within 90 days of the assignment due date. Weekly Assignments/Reports will be evaluated based upon the degree of completion and correctness.
