Gradient Precipitation Of Recombinant Proteins Contained In Silkworm Larvae (Bombyx Mori) With Ammonium Sulphate, Abdurhakhmanov Jaloliddin, Sasmakov Sobirdjan, Khasanov Shuhrat, Ashirov Оybek
CHEMISTRY AND CHEMICAL ENGINEERING
We investigated the protein extract of silkworm larvae. For the first time, an extract containing proteins from silkworm larvae, obtained by fractional precipitation using ammonium sulfate, was studied. As a result of experiment is established, that solutions of ammonium sulfate with a concentration from 20% to 65% are optimal for the sedimentation of protein molecules with a mass in the range of 25 and 45 kDa. Optimal results of the study proposed to use in the process of purification of recombinant proteins.

CHEMISTRY AND CHEMICAL ENGINEERING
The methods of oriented immobilization of lipases on a solid carrier - Silochrome C-80 have been developed. The resulting sorbents were tested in the process of obtaining biodiesel from cotton oil. It was shown that immobilized lipase on Silochrome C-80 with NH2 group has the highest transetrification ability and stability, while in sorbents with the enzyme immobilized with -COOH and -SH groups this value was 87 and 53%, respectively. Biocatalysis using an affinity sorbent of immobilized lipase with the –NH2 group has a high operational stability, which, after 240 hours of operation, retains more than 50%, and after 480 hours, …
