bacteria which can produce d enzyme.

Respected sir/Madam
                         I have planned to produe lipase enzyme from marine water (sea water).My works are as follows
       1.  optimization of diiferent media for the growth and production(2 liter) of lipase  enzyme

Hi every one
Thanks a lot in advance.
I need to isolate bacteria from rhizosphere soil
I have a following doubt in soil sample collection.

Thank so much all for your constructive suggestions and advieces, it's alot to me.
As we all know, mebrane fouling is one of the main problems of the seawater and brackish water desalination plants. Thus, specifically my objective is to identify the type of bacteria in the ...

I am trying to isolate the bacteria from brackish water. I incubated the brackish water for three weeks. When I centrifuge the culture after three weeks, I couldn't get any pellets to extract the DNA. I streak them in LB plates but it will ...

Good afternoon everyone,
I have a difficulity in solidifying the agar medium to pH 3. the agar
that i used is glucose yeast peptone, the composition is as follows,
1. glucose - 5g

We are looking for a test  method that can determine the total count of colonies INSIDE a bar of soap. We would like to obtain a method where we can make a dilution in a broth and then follow a spread plate technique to count the final colonies. We are however not sure how to go ...
