Chromium oxidation, popular and largely explored in natural chemistry because the very starting of this technological know-how, is a subject of present curiosity for the natural chemist as evidenced by way of the continual improvement of recent techni ques and approaches suggested within the literature. Chromium oxidation is an easy strategy which might be simply played within the laboratory and scaled up in in addition.

The control, which was the crude non precipitated extract had no autolytic activity, however this is certainly related to the low concentration of autolysins in this extract. 5 activity using the gel electrophoresis in denaturing conditions. The results are presented in figure 3. Lane 1 is the control which was the 0% ammonium sulfate. Lanes 2 to 5 are the precipitated fractions (0-20%, 20-40%, 40-60% and 60-80%). 5. The complete protein profile of peak 1 as determined by SDS-PAGE is shown in Figure 4.
In fact, for both these detergents, the enzyme activity decreases as the concentration of the detergent increases. The difference between these two detergents is that CHAPS is easier to eliminate by dialysis, while Triton X-100 is very difficult to eliminate from the extract. 2 and 2% CHAPS would provide excellent results. After the treatment with LiCl and the subsequent dialysis, most of the autolysin was found in the precipitate. This would suggest that the compound that renders the enzyme insoluble is also found in the supernatant due to the effects of LiCl.
5) of L. lactis subsp. cremoris ATCC 9596 (Mc5) so as to ensure its purification from the supernatant of cellular remnants and whole cells. In several studies it was found that autolysins are linked to lipids or other membranous components during the extraction process and especially during the purification. They are therefore considered to be hydrophobic enzymes; however, it is often unclear whether or not the enzyme of interest is in fact hydrophobic. Although several classic and more modern methods are available to solve these kinds of challenges, there is still much uncertainty, and further studies are still needed to clearly resolve the purification of cell membrane hydrophobic enzymes.
