Abstract: FIELD: biotechnology. SUBSTANCE: new strain Brevibacterium sp.90 - a producer of lysine is obtained. Strain is able to accumulate the high level of the end product on molasses media with decreased concentration of growth factors. In the process of growing on the medium with molasses (PS - 12-13%) strain accumulates lysine at concentration up to 65 g/l for 72 h under condition of flask shaking, and up to 56 g/l for 60 h in industrial fermenters in the process without makeup. Sugar conversion is 45-49%. Strain does not require high concentration of growth factor (leucine) that allows to carry out the process on molasses without hydrolysate PVC usage. Strain shows decreased aeration requirement. EFFECT: increased yield of lysine. 2 tbl

Title: Process for manufacturing alumomagnesian spinel
Inventor: GLAZYRINA LYUBOV N
IPC: C01F7/16
Filed: 1991-07-03
Granted: 1994-03-30
Abstract: FIELD: inorganic chemistry. SUBSTANCE: magnesium chloride solution is mixed together with solution containing basic aluminum chloride, Al 2 (OH) 4,35 Cl 1,65 , with their concentration being at least 2.5 and 1.25 M, respectively. The alkaline nature of basic aluminum chloride solution used in the combined solution promotes the hydrolysis of magnesium chloride and makes use of neutralizing agent unnecessary. The hydrolysis of magnesium chloride assists in aluminum hydroxyl-ion association which is one of the stages of solid phase transfer. This allows spinel crystallization to conduct at reduced temperatures. The resulting precipitated product is evaporated at temperatures of 600 to 1100 C. EFFECT: high purity and yield of the end product. 1 tbl
