Total Yeast & Mold Count (Total Fungal Count)_A Complete Procedure (BAM, Ch-18)

Total Yeast & Mold Count (Total Fungal Count) is a very important Microbiological testing parameter for Food, Feed, Water, Environmental and other samples analysis. This video represents a detailed procedure for the enumeration of total yeast & mold in a sample.

I haven't received notifications for your posts in a while. I missed you, your team, and your videos! Thank you! Welcome back!

[@MicroChemsExperiments]

So glad to hear this. Actually we were so busy in our professional life. Now, we are back. Stay with us.

[@ammardilawar510]

Thanks for the excellent video. I have few questions 1. What can we use instead of stomacher bags ? 2. How to prepare sample if we have swab samples or environmental samples ? 3. Formula if we have n3 or n4 also ?

[@MicroChemsExperiments]

1. Large duran bottle 2. Dissolve the swab stick in 10ml buffer solution. After shaking and vortex, dilute if necessary. Then analyze. 3. First calculate average from 2 plates. In this way, make 2 values from 4 plates.

Can we use potato Dextrose Agar instead of DRBG Agar

[@MicroChemsExperiments]

Yes you can but you need to add chloramphenicol as a supplement to make it more selective for Yeasts & Molds.

[@ruqiyakhamroon4434]

R can we use potato Dextrose Agar w/chloramphenicol

Hello. Does pour plating method can be used for yeast and mold culture?

[@MicroChemsExperiments]

In that case you have to use SDA media for pour plate

Hi! Great video. Just want to ask did the sample weight change from 25g to 50g?

[@MicroChemsExperiments]

The question is not clear. We took 25g sample for testing

[@Ninxh678]

@@MicroChemsExperiments because according to the FDA-BAM Chp 1 the sample weight stated to be 50g. So I just want to ask did the result for 25g different from 50g?

Is there any chemicals to prevent yeast and mould in packeged drinking water

[@MicroChemsExperiments]

Yes. benzoic acid, sodium benzoate, propionic acid, sorbic acid, and sodium diacetate are used to prevent the growth of yeast and mould

Hi, I am wondering what is the purpose of labeling 2 trial plats? eg: DRBC10-2 / trail -1 and DRBC10-2 /trail -2. Thanks in advance.

[@MicroChemsExperiments]

Contamination can occur in every steps of any microbiological test. So double trial can increase your confidence level of the test.

[@ayakhaled2474]

Incubate plates in upright or invert position

[@MicroChemsExperiments]

Invert

[@ayakhaled2474]

But in iso method 21527-2 is written: 9.2.3 Incubate the prepared plates aerobically, lids uppermost, in an upright position in the incubator at 25 °C ± 1 °C for 5 d to 7 d. If necessary, leave the agar plates to stand in diffuse daylight for 1 d to 2 d.

Yes. Link: kzbin.info/www/bejne/f523n397nM6pqtU

Can we use blending jar instead of stomacher machine

[@MicroChemsExperiments]

Contamination can occur in blender jar. So you can shake by your hand....or you can use vortex mixer

Can we use this method for determination of yeast and mold?

[@MicroChemsExperiments]

Yes

For enumeration need 6 falcon tube then how about determination do we still use 6 falcon tube or just use 2 tube only ?

[@MicroChemsExperiments]

@@sambathsocheata1389 you can use only 2 tubes. It depends on the expected concentration of yeast and mold in your sample
