   The main purpose of our work was the superior use of the paper and cellulose industry’s wastes by using them as substrate in an optimized culture media formula for the yeasts strains development.

  The best results were obtained on culture media with 35% wood hydrolyzed and also with well determined concentrations of sugar beet molasses and mineral supplements.

  The yeasts growth were verified by optical density (determination meaning the cells number which are present in a well determined liquid volume), the reducing sugar’s consumption and by the Ph dynamics. The results obtained with these yeasts strains selected from different natural sources and named D4 and D5, were compared with those obtained by using identified yeasts strains kept in the microbial collection of our institute, such as Candida robusta and Candida tropicalis.

  Our conclusion indicates that different types of hydrolyzed wood wastes can be recycled by microbiological ways, so that by so called “Green technologies” which seems to act friendly to our environment, while one of our main tasks was to use materials and technologies as natural as possible.
