Chemical composition of molasses, used as sources of carbohydrates for leucine biosynthesis has been studied. Influence of molasses parameters on biomass growth and leucine synthesis in the process of cultivation of the producer of Corynebacterium sp. genus is proved. The results are processed by the personal computer with the use of applied statistical(More)
The effect of threonine technical sources on the homoserine biosynthesis by the threonine auxotroph Brevibacterium flavum 2T when cultivated on sucrose and acetic acid containing media was investigated. Various threonine sources (corn extract and fodder yeast, microbial biomass and soybean meal hydrolyzates) prepared by means of different hydrolyzing agents(More)
We have begun to apply ambient noise surface wave tomography to broad-band seismic data obtained in Europe, North Africa, the Middle East, and Central Asia. The goal is to improve the calibration of surface wave propagation in aseismic areas. Ambient noise tomography (ANT) generates surface wave dispersion maps to periods as short as 6 sec across large(More)
