Malt shakes any one?
To all of the hard working mentors and students in the program, have a great and happy holiday. This week in lab I have made yet another media to try and isolate these fungal cells. In my research I found an interesting article talking about endophytes actually giving plants tolerance to pollutants in the air, like from automobiles. I am amazed at how symbiotic these relationships are between endophytes and plants and just how much each one can gain from each other. The malt extract I am using is going to require 20 grams of malt extract and 9 grams of agar solution as a standard from the dichotomous key I am using.

I will have to admit even with all the stresses of life weighing me down, the time spent in lab and with the great minds that encompass that area has been a centering point for thought, laughter, and of course some science work. I am thankful for all the joy this class brings me. Now with that said I made corn meal agar and will make malt extract agar this week to go along with the new dicotomist key we found. That way I can see if the microbes I have isolated are in fact endophytes. These media should help differentiate and help isolate the fungus I am looking for. Untill next week here is a video for your enjoyment.

This is why endophytes are important!

Lots of things growing and new media to inoculate!
In this
weeks lab I got to do more testing on my unknown bacteria from the grass
seeds I broke up. It is a pure sample to test on. I found it is Gram
positive bacillus bacteria, microaerophilic, triptone negative and
fermented glucose, fructose, and lactose while producing gas in all
three of them. I will also try to recreate the inoculation of a fungus I
got to grow from sterile grass with the root and the tips of the blades
cut after sterilization. I found many articles that showed scientist
inoculation endophytes at room temperature instead of the 37 degrees I
am currently inoculating at, so I am adding this variable to my process
and going to see what happens at a different temp.
Endophytes can clean up polluted and contaminated soil from explosives like TNT.

Well it is something.
I started today with little hope, seeing as i am still having trouble getting anything to grow with the techniques I found online. I was pleasantly surprised to find that one of the agars from a grass seed inoculation I had done last week had a nice colony on it, and only the one! After doing a gram stain I found that the unknown in question is a gram positive bacillus microbe. After making a TSB today I will do more testing to further identify the microbe tomorrow.
