Buletinul AŞM. Ştiinţele vieţii. Nr. 2 (314) 2011 Abstracts This article reports the results of an investigation performed to assess the in uence of the temperature, medium pH, and cultivation duration on the multiplication of the Saccharomyces cerevisiae CNMN-Y-20 and Saccharomyces cerevisiae CNMN-Y-21 yeast strains and carbohydrate biosynthesis. It has been found that the optimal temperature for the multiplication of the above yeast strains is +15°С, and the maximal carbohydrate content in the biomass is accumulated in a stationary phase of growth, when the duration of cultivation is 120 hours. It has been established that the optimal medium pH for carbohydrate biosynthesis is 5.5. 16 references, 9 gures UDC: 504.53.052/.062.4 THE INFLUENCE OF DIFFERENT TECHNOLOGIES OF SUGAR BEET CULTIVATION ON THE MICROBIAL ACTIVITY IN SOIL. Corcimaru S., Mereniuc Gh., Boincean B., Bugaciuc M. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2011. No 2 (314), p.166-170. Sugar beet was found to have a negative in uence on the general soil microbial activity and, as a result, on the soil organic matter content when grown continuously without fertilizers. This negative in uence was signi cantly stronger than the one of continuous alfalfa, signi cantly lower than the one of continuous corn, and comparable to the ones of continuous winter wheat and sun ower. The negative effects of continuous sugar beet on the soil microbial activity could be only partially removed by adding organic and mineral fertilizers. Inclusion of sugar beet into the ecological crop rotation with organic fertilizers caused neither inhibition of the soil microbial activity nor decreases in the soil organic matter content. 5 references,1 table. UDC: 637.146.32:612.398.192. AMINO ACID COMPOSITION AND NUTRITIONAL VALUE OF COMBINED SOUR CREAM PRODUCED BY USING LOCAL STRAINS OF LACTIC ACID BACTERIA. Shvets Svetiana, Burtseva Svetlana, Garaeva Svetlana, Burets Elena, Coev Ghenadie. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2011. No 2 (314), p.170-177. Amino acid composition has been studied in a sour cream combination produced from a mix of cow and soy milk by using a combination of the local strains of lactic acid bacteria (IBC). It has been found that the samples of the sour cream combined at a ratio of 70%:30% and 50%:50%, prepared in the laboratory conditions using a thermostatic method, qualitatively cover the daily needs in all essential amino acids based on the total content of essential amino acids; while the characteristics of the protein nutritive value (the indices E/N and E/T) are close to those of casein. The sour cream produced from a mix of cow and soy milk (70%:30%) is more rich in essential, immunoactive, glycogenic, and sulfur-containing amino acids, which allows it to be recommended for production. 19 references, 3 tables, 1 gure UDC 504.06; 504.4.054 THE IMPACT OF SURFACE ACTIVE SUBSTANCES ON THE BIO-CHEMICAL PROCESS OF AMMONIUM ION OXIDATION IN NATURAL WATERS. Spataru Petru, Sandu Maria, Tarita Anatol, Lupascu Tudor, Negru Maria, Mosanu Elena, Turcan Sergiu. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2011. No 2 (314), p.178-184. Ammonium compounds can be found in natural waters as a result of contamination with wastewaters or drainage water from agricultural areas where nitrogen fertilizers are used. Studies show that surface active substances (SAS) are present in river waters since conventional biological treatment methods are less effective for their puri cation. The SAS are toxic to 197

This work concentrates on the studies of the in uence of various surface active substances on the biochemical process of ammonium ion oxidation in natural waters. 19 references, 1 table, 3 gures UDC: 631.432 SOIL FERTILITY RESTORATION. A THEORETICAL MODEL OF ORGANIC SOIL FORMATION. Coronovschi A., Jabin V., Rusu Maria. // Buletinul Academiei de Ştiinţe a Moldovei. Ştiinţele vieţii. 2011. No 2 (314), p.184-190. The paper presents a new theoretical model of the organic soil formation process. The model proposes a new concept concerning processes of the multifunctional role of soil organic matter in productivity restoration during soil exploitation. The paper shows the results of a numerical experiment proposing the conditions of soil exploitation that can facilitate to restore its fertility. 12 references, 4 gures. 198 Abstracts
