What BT612P Assignment 1 asks
This assignment requires students to perform calculations and quality audits based on three laboratory practicals: media preparation, conidial inoculum verification, and wheat-bran solid-state fermentation. Students must use their specific VU ID digits to determine assigned values for volumes, counts, and experimental results. The final submission must demonstrate accurate calculations, identify specific procedural faults based on an assigned incident, and critically evaluate enzyme yield claims. The work must be submitted directly into the VULMS inline response field.
-
1
Formulate both media
4 marksCalculate the required mass in grams for peptone, yeast extract, and glucose for a YPD batch, and the mass of dehydrated PDA powder for a specific volume. Show one mL-to-L conversion and specify the correct timing and method for recording the YPD pH before sterilization.
-
2
Verify the inoculum
6 marksList five haemocytometer counts and their mean, then correct for chamber volume and a 1:10 dilution to estimate the original stock conidia/mL. Use the C1V1 = C2V2 formula to determine the stock and diluent volumes needed to prepare 10.0 mL of target suspension. Propose one independent check for the count or pipetting process.
-
3
Audit your assigned incident
4 marksIdentify the specific faulty record or control based on an assigned incident number. Explain the consequence of this fault for experimental interpretation and propose a corrective action. Include a description of a notebook entry or measurement that would make the correction auditable.
-
4
Qualify the amylase claim
6 marksCalculate the net enzyme activity by subtracting the matched control from the inoculated reaction product, then convert this to U/mL for the original extract and total apparent U in 100.0 mL. Challenge the claim that this result proves absolute alpha-amylase yield per gram of bran by identifying necessary additional measurements or validations.

Lesson covered
The questions in this assignment come from this lesson. Read it in the BT612P handout before you open the assignment file, then practise it with the MCQs and past papers.
Solution
The solution has not been added yet. Request it from the download box and it will be added to this page, usually within a day.
Before you submit on VULMS
- 1 Start on the questions in the assignment file now. The solution will be added to this page once it is written.
- 2 Write the final answer in your own words. VU checks assignments for copying, and copied work gets zero marks.
- 3 Save your answer in the file type the assignment file asks for, and name it with your student ID, for example BC260012345.
- 4 Open the file once more to check it is not empty or corrupted, then upload it on VULMS before 11:59 pm on Tue 17 Nov.
Questions about this assignment
When is BT612P Assignment 1 due?
Tuesday 17 November 2026 at 11:59 pm. VULMS does not accept files after the deadline.
When will the solution be added?
Most solutions are up within a day of a request. Requests tell us which ones to write first, and 0 students have asked for this one so far.
Can I submit the solution as it is?
No. VU checks assignments for copying, and copied work gets zero marks. Use the solution to check your method, then write your own answer.
What file do I submit?
The assignment file says which file type to upload and lists any extra instructions from your instructor. Name the file with your student ID before you upload it on VULMS.
