Sample Text:
Abstract Delisea pulchra and Ulva australis are two widely found macroalgae known for their ability to remain free of fouling organisms, including bacteria, invertebrate larvae and other algae. It has been proposed that the algae achieve this by using a collection of antibacterial and anti-communication properties, originating from both the alga itself and from the bacteria that colonise its surface. We assessed these functions by comparing functionality found in the two targets; crude extract of the algae and the bacterial isolates of the microbial surface community. We found that both targets possessed antibacterial activity. We also found that neither target produced AHLs but the isolates were able to inhibit such signalling. Overall, the results indicate that the algae may combine their innate functionality with that of their microbial community to produce a wid...

Isolation and identification of Azotobacter from Soil Sample

This student studied:
University of New South Wales - MICR2011 - Microbiology 1

This experiment explores the various techniques used to help isolate and identify this bacterium. Several biochemical test such as gram stain, motility, catalase and oxidative test were performed over several weeks to differentiate it from the countless bacteria which are also present in a soil sample. In this experiment, we used a specific selective media, Burk’s medium, to incubate the bacterium in.
