UV light is part of the electromagnetic spectrum, but with shorter, higher energy wavelengths than visible light. Prolonged exposure can be lethal to cells because when DNA absorbs UV radiation at 254 nm, the energy is used to form new covalent bonds between adjacent pyrimidines (cytosine-cytosine, cytosine-thymine, or thymine-thymine) called pyrimidine dimers
SUMMARY The contribution of enzyme tests to the accurate and rapid routine identification of gram-positive cocci is introduced. The current taxonomy of the genera of aerobic and facultatively anaerobic cocci based on genotypic and phenotypic characterization is reviewed. The clinical and economic importance of members of these taxa is briefly summarized. Tables summarizing test schemes and ...
Results of antibiotic sensitivity test was presented in table-2 showed that Bacillus amoxicillin (AMcereus (MTCC 1305) was the most sensitive organism inhibited by the extract of 14 isolates followed by Bacillus subtilis (MTCC 1789), Salmonella typhi (MTCC 531), Escherichia coli (MTCC 1667), Bacillus cereus (ATCC 10876), Staphylococcus aureus (MTCC
Apr 11, 2018 · Inorde to obtain the results of these four tests, three test tubes are inoculated viz tryptone broth (indole test), methyl red – Voges Proskauer broth (MR-VP broth), and citrate. IMViC tests are used in identification and differentiation of some enterobacteriaceae members.
TEST RESULTS. Growth On DTC agar. DTC agar was the enrichment media we chose to grow Serratia marcescens. The usually red colonies had a bluish tinge when seen against the background of the blue DTC agar. The colonies were pigmented only at room temperature or about 25 degrees Celsius. Growth On T- Soy agar.
