Thirty high activity yeast strains saccharolytic and acidifying were isolated from sugar cane press juice and molasses from a sugar plant (grown on a solid semi-synthetic culture medium supplemented with 3 g of sucrose and incubated for 72 h at 40 ° C. the purification of the strains is verified by microscopic control after three subculture cycles in liquid medium and a passage on solid medium in a Petri dish 80 mm in diameter. the identification was carried out according to biochemical tests, physico-chemical and microscopic. These culture, purification and identification have isolated a strain which we named LES16 characterized by its temperature tolerance, which considerably increases during fermentation. This is a Candida sp which presents optimal conditions (pH 5, 3 g / l sucrose, 1 g / l (NH4) 2SO4 and 40 ° C) an enzyme activity of 4228 IU / l. has a major interest in the application of a technique primarily based on the use of a mixed starter containing lactic acid bacteria and yeast fermentation and strong acidifying power. Localization of beta-fructofuranosidase activity LES16 strain was obtained by culture on the semi-synthetic liquid medium supplemented with 3 g of sucrose. The centrifuge technology and cell lysis have produced more cell fractions to search for enzyme activity.

This project is part of the logistics control strategy implemented by the company mainly logistics costs represent a substantial percentage in its turnover. This study is to control logistics costs plenty Company BIMO in order to have a follow-up of the latter. In terms of results, the values found by the management control department (2616 Kdh) and what we assume ugly to the daily calculation tool (2624Kdh) is not critical, a difference of 8 Kdh; a difference measured at + 0.28% of the actual cost of which is the return of non-compliant commands, these results confirm that the implementation of the tool we developed control and monitoring of reliable and efficient logistics costs.

The purpose of this article is to examine the correlations between various parameters involved in the management of quality and management control, to understand the actual operation of both functions in the companies' logistics and transportation sectors in Morocco.
