Our findings allow us to describe the colony and cell morphology of both species; to state the Gram type of each, and to state which strain is capable of growth on the selective medium. First, we observed good growth in three of the four plates, two NA and one EMBA. coli that showed overlapping and one where a little agar was scraped off of the surface.
Results (~ half a page of text, plus diagrams & photos) Report your findings. How good was your streaking (were single colonies evident)? coli, from left to right, and 2 EMBA plates at the bottom with M. As a consequence, except for one with the overlap, it was not hard to pick up a single colony with the loop.
We collaborate with Laboratory of Bioinformatics of dr.
Vohradský at the Institute of Microbiology of the ASCR ( ).
So your sample will be sent to a lab to allow the cells to grow.
If there is an infection, the infected cells will multiply. BIOC1010: Introduction to Microbiology YOUR NAME: Jacopo Gabrielli Laboratory report: experiment 3 Colony growth and analysis of two bacterial strains Introduction (For this report, I give you an example of how I would complete this section.Therefore, you don’t need to do this section yourself).Studied Clinical Bioanalytics at the Institute of Chemical Technology in Prague and Process Engineering at the Czech Technical University in Prague.Bacteria are a large group of one-celled organisms. Some types of bacteria are harmless or even beneficial. A bacteria culture test can help find harmful bacteria in your body.Finally, individual colonies can be picked from a nutrient agar plate and various diagnostic tests performed to further characterise the isolate. We then carried out a Gram stain on the colonies from the NA plates to determine the cell morphology and Gram type of the two strains.The results of the Gram stain were compared with that from the Gregerson test, which also discriminates between the two Gram types. BIOC1010: Introduction to Microbiology After two days of incubation at 30 °C and storage at 4°C we analysed the Na and the EMBA plates. The streaking was well divided into the three sections in all plates except for the NA with E.Streptomycetes are very important producers of wide variety of biological active compounds, such as antibiotics, antifungal (nystatin), antiviral, antitumoral, anticancer agents (doxorubicin), immunosupressants (rapamycin), siderophores (deferoxamine), pigments, volatiles (geosmin) (Hopwood, 2007; Bentley et al., 2002).They are also involved in decomposing the insoluble remains of other organisms such as lignocellulose and chitin, that makes them central organisms in carbon recycling (Bentley et al., 2002).The cells in your sample will be taken to a lab and put in a special environment in a lab to encourage cell growth. But some types of bacteria grow slowly, and it may take several days or longer.Bacteria culture tests are used to help diagnose certain types of infections.
