Gram Staining Procedure_Microbiological Technique_A Complete Technique (BAM: R32)
The Gram Staining is one of the most crucial staining techniques in microbiology. It gets its name from the Danish bacteriologist Hans Christian Gram. Gram stain is a method of staining used to classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria.
This video explained the detailed procedure and result interpretation of Gram Staining of Bacteria.

Settle Plate Method | Environmental Monitoring | Microbiological Quality of Passive Air | FDA, 2004
Переглядів 9 тис.10 місяців тому
In the Settle Plate Technique, petri dishes containing culture media are exposed to the air for a given time in order to collect biological particles which “sediment” out and are then incubated. The bacteria-carrying particles are allowed to settle onto the medium for a given period of time and incubated at the required temperature. A count of colonies formed shows the number of settled bacteri...

Determination of Starch Content | A Complete Procedure | Acid Hydrolysis Method
Переглядів 16 тис.Рік тому
Starch constitutes the major component of the polysaccharides in most foods and consists mainly of amylose and amylopectin. The test sample is dispersed in water and heated in acidic solution to hydrolyse the starch, releasing the sugars. The resulting sugars are then determined by titration with Fehling solution according to the method of Lane-Eynon. The sugar content is further converted into...

Hai, thank you, wonderful video ,i need the reference for this ,, kindly guide me...i have to document alos
there are white colored center dots on pink color colony, are these coliform and to be counted?
Yes. Those are also coliform
Whatu have used is durham's tube for gas production ? is it peptone watet??
BGLB broth is used along with Durham tube
How to determinate mb value of carban?
Hi. May I know where does the 0.00584 in the last equation comes from? Thanks
I want to see further steps for heavy metal analysis (how to determine quantity of any metal pb/cr/zn)...do you have any video on this??
How to avoid measuring mineral acids (e.g. sulfuric acid) and organic acids, only I would like analyze Free fatty acid content.??
Thanks
Calculation is wrong
thank you! is this also aplicable for meat analysis?
can we use peptone water instead of saline water
J'adore la vidéo svp 🙏 pouvez vous faire une version en français pour nous
Thank you very much. Unfortunately at this moment we can't make videos in French. You can use translator or select french subtitles while playing the video
Please also explain the calculation part
Hey, thank you . I would like to know, is it applicable for PAH analysis??
Well explained thanks
Please what is the value 28.05 used in the calculation
Nice handling...
Very helpful
Thank you
Wow it's Amazing and helpful❤
Thank you
welcome lab first day noobs ... cleaning glassware for 8 hours a day before they let you do anything cuz you're on the bottom rung of the ladder and the newest staff there ..
If you take boric acid with measuring cylinder.. Beleive me you will always get different results in each experiment.. take class a or class b burette for taking boric acid. So many things worng in this experiment
lactometer is important
Is for the fruit Slurry is the same.
39.2-25.6= 13.6 25.6???
Pipettes to measure 0.83 ml difficult to get, also it is better to take hard compound (i.e. anhydrous Na2CO3) to standardize
What is the normality use for preparing 40%solutin
No its 26.8
Its wrong, standards always weigh in volumetric glassware
Superb .plz do a video about to check acidity of cheese
I have a doubt about how the calibration curve was made for that method, it is only done in solvent?...should some correction be made for the determination of the concentration?
How will you identify the e. Coli and coliforms
Please ask any question in the following email: mail.mic.chem@gmail.com
How is Peptone salt solution preparation done because in this you have told something else about the formula to make it and in the video of Ecoli you had told something else, please do tell🙁🙁
sir, why you have used filter paper inside the thimble? does only thimble was not enough if we close it with cotton? kindly, respond early.
How to decide to take 3.35gm sodium oxalate
Why do we need to keep 45° f the vial?
I am a Hindi board student but I understood this video very well because of easy explanation. Microchem's experiment team your videos is amazing! Thank you so much😍😍😍
Hi, Thank you for the Video, very informative. Also can the same plate be used for bacterial and fungi incubation? since incubation temperatures and duration are different for bacteria and fungi?
What standard peroxide value ??
Can you tell me what is the standard method you use to do this procedure? Thank you 🙏
There's a mistake in your analysis the equivalent weight of sodium thiosulfate is 248.16g so if we want to make 0.1 N Sodium thiosulfate we need 24.6g not 2.48 g
Emergency 📍📍📍 I put it on hot oven 130° for half hour then i let it till next day for 50° (coz it was time to close the lab)..will it affect the result??
Yes. You should finish the experiment om the same day
Is there any way to fix the result without doing the experiment again?
Can maconkey used in determination of faecal coliform in food sample which is in solution form
Yes. You can use
Considering EMB and sMAC is used after 48 hours, is there need to prepare it on first day?
Not necessarily
👍👍👍👍👍
temperature of hot plate? do i need magnet? can i determine orange peel's fibre?
It's error in calculation How 9×10×0.1 =
