Question from a student Question on 2012-2013pp Q5

Dear Kkkkkk,

Apple juice: E.coli  (low acidity, it can tolerant to pH4)

A: Correct

Steak: Staphylococcus aureus (have extracellular enzymes to digest the protein, so high protein content is ok )

A: No. E. coli, grow faster.

Beef: pseudomonas (it can grow at low temp and low sugar content food)

A: No. Listeria....Low temperature and high salt

White wine: acetobacter species (low pH)

A: Correct. But the reason is white wine has ~15% alcohol

bagel:  Saccharomyces cerevisiae (low aw, which many bacteria cannot grow) 

A: No. Aspergillus........low Aw and moderate sugar. Yeast can grow but limited in space and may have growth advantage if high sugar.

Best,

HSK

On Wed, May 6, 2015 at 7:25 PM,

Dear Prof. Kwan,

     Good evening. I want to ask whether my answers are correct because my answers are different from my classmates. 

My answer are:

Apple juice: E.coli  (low acidity, it can tolerant to pH4)

Steak: Staphylococcus aureus (have extracellular enzymes to digest the protein, so high protein content is ok )

Beeif: pseudomonas (it can grow at low temp and low sugar content food)

White wine: acetobacter species (low pH)

bagel:  Saccharomyces cerevisiae (low aw, which many bacteria cannot grow) 

                Thank you for answering my questions.

Question from a student 20150506

---------- Forwarded message ----------
From: Prof. HS Kwan (School of Life Sciences) <hskwan@eservices.cuhk.edu.hk>
Date: Wed, May 6, 2015 at 9:23 PM
Subject: RE: 2014R2-FNSC3180 : Food Microbiology: Coverage of topics in final examination of FNSC3180
To: AAAA

Q&A:

Firstly, can E. coil tolerate low temperature, such as 5 degree celcius, such as apple cider and what is the upper, lower limit for its growth temperature and pH?

A: Apple cider after commercial sterilizaion is usually stored at room temperature so E. coli can grow. 5C would be too low for E. coli to grow.

Secondly, can Listeria monocytogenes growth at pH 5.2, such as vegetables?

A: Yes

Thirdly, Viruses can only growth on people but how they can be foodborne pathogens?

A: Viruses cannot grow on food but they can survive on food. When we eat the food with the foodborne viruses that can infect us, they would grow in us and cause diseases.

Best,

HSK

---

Q:

Sorry for bothering. 

I wonder to ask you three more questions. 

Firstly, can E. coil tolerate low temperature, such as 5 degree celcius, such as apple cider and what is the upper, lower limit for its growth temperature and pH?

Secondly, can Listeria monocytogenes growth at pH 5.2, such as vegetables?

Thirdly, Viruses can only growth on people but how they can be foodborne pathogens?

Hope to hearing from you soon.

Question from a student 20150506

Q: 

I am student of your class FNSC4180 and have some questions on past paper during revision, it would be kind of you to help. There are questions on "Hurdle theory” asking whether the conditions and treatments are effective to control the growth and survival of the target organism. I am not sure how to determine whether the method is effective or not. Is it effective once one of the condition out of the tolerance limit of that bacteria?so the explanation just focus on the tolerance limit of the bacteria?

I would like to know if these answers are correct. Thank you very much for your help.

2011-2012. 6

i.                Not effective as Listeria monocytogens is psychrotroph which can grow survive under 4-40^oC

ii.              Same as i.

iii.             Not effective, 0.85 is the minimal aw for germ positive bacteria

iv.             Effective, 11% salt is too high for survival of Staphylococcus aureus ,it can only tolerate up to 10%

v.              Not effective as aw0.9 is not low enough to its growth

vi.             Effective, Clostridium botullinum is obligate anaerobe which can be killed by 5% of O2.

vii.           Effective, though there is no O2 but the temperature is too high for a mesopile like Clostridium botullinum and obligate anaerobe survive in low Redox.

viii.          Effective as Pseudomonas spp. is aerobe which require O2 to survive.

ix.             Effective, pH 4.2 is too low for bacteria

x.              Same as ix.

A: Yes, basically one parameter beyond the tolerance limit would control the microbial growth or survival.

I only have enough time to check your answer to this set of questions:

2011-2012. 6

i.   Not effective as Listeria monocytogens is psychrotroph which can grow survive under 4-40^oC

OK

ii.              Same as i.

No. Listeria cannot grow at 40C

iii.             Not effective, 0.85 is the minimal aw for germ positive bacteria

Effective. 0.85 too low for Listeria

iv.             Effective, 11% salt is too high for survival of Staphylococcus aureus ,it can only tolerate up to 10%

OK. Although some reports showed that Staphylococcus can tolerate 11% salt

v.              Not effective as aw0.9 is not low enough to its growth

OK

vi.             Effective, Clostridium botullinum is obligate anaerobe which can be killed by 5% of O2.

OK

vii.           Effective, though there is no O2 but the temperature is too high for a mesopile like Clostridium botullinum and obligate anaerobe survive in low Redox.

OK

viii.          Effective as Pseudomonas spp. is aerobe which require O2 to survive.

No. Pseudomonas can use nitrate for anaerobic respiration

ix.             Effective, pH 4.2 is too low for bacteria

OK. effective for controlling Salmonella

x.              Same as ix.

No. pH 4.2 not low enough to control E. coli O157:H7
