the bacteria grown can ferment lactose. The results acquired by our test was positive with color change to pink. Hence the unknown bacteria was gram-negative and can ferment lactose. Amongst Escherichia coli and Proteus vulgaris‚ the result MacConkey agar confirmed that the unknown bacteria was Escherichia

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

2. Experimental 2.1. Experimental procedure for the synthesis of bone-like CS-PEG-HA-ZrO2 nanocomposites (BNC I-III). At first‚ ZrO2 nanoparticles (NPs) were synthesized by using the previously reported method [16]. Briefly‚ aqueous solution of sodium hydroxide (purchased from HiMedia Private Ltd.) (40 ml 0.05M) was slowly added in zirconium oxychloride octahydrate (purchased from Merck India Ltd.) solution (100 ml 0.01M) prepared in methanol-water (1:1) at 5 oC temperature. The mixture was stirred

research organization‚ published results today describing the successful construction of the first self-replicating‚ synthetic bacterial cell. The team synthesized the 1.08 million base pair chromosome of a modified Mycoplasma mycoides genome. The synthetic cell is called Mycoplasma mycoides JCVI-syn1.0 and is the proof of principle that genomes can be designed in the computer‚ chemically made in the laboratory and transplanted into a recipient cell to produce a new self-replicating cell controlled
