The washed mycelia containing allosamidin (0.7 m g) was resuspended in an inorganic salt solution (50 ml) consisting of KCl 0.05%, K2HPO4 0.1%, MgSO4· 7H2O 0.05%, FeSO4· 7H2O 0.001%, (NH4)2SO4 0.2%, pH 7.2, or in a chitin medium (50 ml), and the suspension was incubated ...
FeSO4 solution mixed with (NH4)2SO4 solution in 1 : 1 molar ratio forms a double salt, FeSO4.(NH4)2SO4.6H2O (Mohr salt) which ionizes in the solution to give Fe2+ ions. Hence, it gives the tests of Fe2+ ions. CuSO4 solution mixed with (NH4)2SO4 solution in 1 : 1 molar ratio...

In addition, from the point of view of solution chemistry, PAC poly aluminium chloride is the kinetic intermediate product of the hydrolysis-polymerization-precipitation reaction process of aluminum salt, which is thermodynamically unstable. Generally, liquid PAC products should be used...
Furthermore, by the experiment in an inorganic salt solution, it was shown that allosamidin could not induce the chitinase production without addition of N, NЈ- diacetylchitobiose. These results show that allosamidin can activate transcription of the chitinase gene through the two-component ...

As with YecA, the addition of FeSO4 resulted in a broadening and flattening of most of the 1H resonances due to the paramagnetic properties of iron (Fig. 5A, red trace). The reduction in signal was more pronounced for 1H resonances that were nearer to the predicted metal-binding site ...
Why does a sodium street lamp give off a yellow color, whereas a neon light gives off a red color? What is it that makes the FeSO4 solution turn out blue in color? Why are [ C o ( N H 3 ) 5 C l ] C l 2 named as pentaaminechloroCOBALT(iii)chloride but not pentaaminechloro...
