How much Agar do you need to grow bacteria on a Petri dish? How long does it take to culture Mycobacterium tuberculosis? What is doubling time in bacterial growth? How long does the lytic cycle usually take? What is the stage when no bacterial growth occurs?
Why is agar a useful substance in the microbiology lab? How is sunlight used in photosynthesis? How do Chlorophyta move? How does bacteria get into the bladder? How does the Tevatron work? How was the water cycle discovered? How do flowering plants grow?
Although many bacteria grow in a free-living, ‘planktonic’ state, it is quite common for them to adhere to surfaces by producing extracellular polymeric substances (EPS), e.g. biofilms. Due to their higher resistance against antimicrobial agents, an interesting option in antibacterial research ...
Red algae are an appreciated source of food in several different parts of the world. Red algae are for instance used to make agar agar and carrageenans. In Japan, red algae has been cultivated for at least three centuries to make nori and the speciesPorphyrayezoensisandPorphyra teneraare espec...
Gram negative bacteria + Viruses – – – + – MRSA, meticillin-resistant Staphylococcus aureus. a Cotton, rayon, polyester or macrofoam. Brush-textured swabs perform poorly on wet surfaces. Empty cells indicate lack of data. Contact plates Contact plates are convex agar plates that can be ...
Ice cream that melts too quickly is no fun to eat! Stabilizers can help here too, by both slowing the rate at which ice cream melts and maintaining its shape better, as it does melt. Top: fast melting ice cream. Bottom: slow melting ice cream ...
7. Agar, 'What Happened in the Sixties?' 577. 8. For 'galvanising events', Silent Spring, the Smarden spill and Torrey Canyon disaster, see G. Kroll, 'The "Silent Springs" of Rachel Carson: Mass Media and the Origins of Modern Environmentalism', Public 68 A. CASSIDY ...
This slide count does not discriminate between living spores and dead ones, but, since dead ones can still cause an allergic reaction and carry toxins, this subtlety is unimportant. The number of colonies that grow out over the agar in a culture dish usually provides a lower estimate of mold...
Hektoen Agar medium shows the presence of peptone that acts as a carbon source for the bacteria that grows there. After the preparation of the medium, the agar appears to be green-colored. The agar powder must be kept in a stored container with a tem...
Explain how conjugation can lead to an increase in antibiotic resistant enteric bacteria. What would happen if you put pGLO directly onto an agar plate and you checked on it after letting it incubate? a. It would glow. b. It would grow. c. Nothing. d. E.coli ...
