Good video, i have quation while open plate lid until the liquid agar be solid have u ever the plate countaminated, what u to do to make sure that open lid plate agar until solid could'n countaminated ?
There is no chance of becoming contaminated inside the biological safety cabinet. So, use a calibrated Biosafety Cabinet and monitor it's microbiological quality by settle plate technique periodically.
Same methods can we use for Drinking water or juice analysis? One more request if you possible please upload determination of yeast and Molds and Magnesium analysis in Drinking water. Thank you very much.
I’m stuck at a calculation. My plate count is 52 and Dilution Factor, 10^-3 Volume of sample plated is 0.1ml. My final answer is 5.2x10^4CFU/ml The accepted count is

I have a doubt regardung the buffer preparation.is the 500 ml buffer convert into 1000ml and from that only 1.25 ml is then add to 1000ml distilled water for working buffer dilution preparation?please rectify my doubt as soon as possible.
Very good explanation thanks a lot

can you help me with what TPC count should be considered in acceptable range
for frozen fruits and vegetables?
Very good and in detail explanation. Can you make same video for total coliforms. How to count and which method is highly accurate. MPN OR Plate?
Video for coliform is already uploaded. Please find from the video list of this channel. Plating method is more accurate
Can you tell me what is the standard method you use to do this procedure? Thank you 🙏
