+ | M9 | ||
+ | M9+Glucose | ||
+ | M9+CS (catechu+slaked lime stock) | ||
+ | M9+Glucose+CS (catechu+slaked lime stock) | ||
+ | The samples were processed (passed through bacterial proof filters of 0.22µ) before inoculation so as to eliminate chances of growth due to presence of carbon source in the collected sample. | ||
+ | Hence a flask with M9 medium was also inoculated and checked for growth so as to ensure that the bacteria are not growing due to the carbon source in the sample but are using the carbon source provided in the medium.The choice of minimal medium was also made keeping in mind the single carbon source utilisation by the organisms. | ||
+ | Growth was observed in all the flasks, except the flasks containing only M9 medium without any carbon source, in less than 72 hours of shaker incubation at room temperature. | ||
+ | No growth/turbidity in the flasks containing only M9 medium proves that the carbon source from sample was successfully filtered & thus has proven to be an efficient negative control. | ||
+ | Moreover, reduction in the intensity of the red colour (due to catechu extract in the medium) was observed after 24 hours. | ||

Isolation of organisms and identification by 16S rRNA sequencing
Isolation on solid media after enrichment of samples and identification of the isolates by 16s rRNA sequencing
Experiment 4:
In search of potential enzymes that degrade catechu!
Experiment 5:
DEGRADATION - Chewing Catechu
Experiment 6:
Cloning - Brings out the best in you!
Molecular cloning of the gblock fragments in pSB1C3 backbone (digestion, ligation, transformation) and their confirmation by diagnostic digest agarose gel run.
Experiment 7:
SDS-PAGE Protein Characterisation
After analysing a successful cloning, the plasmid DNA was then transferred into DH5a cells to have growing transformants for characterising protein expression.
Experiment 8:
Content not given
Content not given
Experiment 9:
Versatility - Testing on dyes
Degradation of common lab dyes. Clearance around the colony observed on plates containing several dyes.
