В работе определена продуктивность и эффективность синтеза внеклеточного фермента β-фруктофуранозидазы дрожжами D. hansenii на питательной среде из мелассы. Показано, что эффективность культивирования дрожжей D. hansenii на питательной среде из мелассы зависит, прежде всего, от штамма. Установлено, что наиболее продуктивным и эффективно синтезирующим внеклеточный фермент β-фруктофуранозидазу являются дрожжи D. hansenii штамм Н4651. Наибольшая продуктивность и эффективность синтеза внеклеточного фермента β-фруктофуранозидаза у дрожжей D. hansenii штамм Н4651 проявляется при культивировании на питательной среде из мелассы без дополнительных биогенных веществ при температуре 20 oC. Установлено, что потребление редуцирующих веществ не адекватно количеству синтезируемой биомассы дрожжей D. hansenii. Содержание редуцирующих веществ после 50 час культивирования дрожжей D. hansenii Н4651 начинает увеличиваться. Полученную закономерность увеличения РВ в культуральной жидкости можно объяснить синтезом дрожжами D. hansenii внеклеточного фермента β – фруктофуранозидаза, которая гидролизует сахарозу в питательной среде. Наибольшая удельная скорость роста наблюдается у дрожжей D. hansenii Н4651 при температурах культивирования 15 и 20 oС. Выход биомассы дрожжей D. hansenii Н4651 превышает выход биомассы при культивировании дрожжей D. hansenii штаммов Н433 и Н18-3.</p></abstract><trans-abstract xml:lang="en"><p>Distribution D. hansenii in different substrates can be explained sufficiently high hydrolytic activity, which is a prerequisite for their use in biotechnology to produce various biological products, in particular lytic enzymes. The paper is picked productivity and efficiency of synthesis of extracellular enzyme β-fructofuranosidase D. hansenii yeast nutrient medium from molasses. The efficiency of D. hansenii yeast culture in a nutrient medium of molasses depends primarily on the strain. It was found that the most productive and efficient synthesizing extracellular enzyme β-fructofuranosidase is yeast strain D. hansenii H4651. Maximum productivity and efficiency of the synthesis of the extracellular enzyme β-fructofuranosidase D. hansenii yeast strain H4651 seen when cultured in a nutrient medium from molasses without additional nutrients at a temperature of 20 oC. It was found that the consumption of reducing substances is not an adequate amount of yeast biomass synthesized D. hansenii. The content of reducing substances after 50 hours of cultivation D. hansenii yeast H4651 Uwe-creases. The resulting pattern PB increase in liquid culture may explain synthesis drozh-Jamie D. hansenii β – fructofuranosidase extracellular enzyme which hydrolyzes sucrose medium. The highest specific growth rate observed in yeast D. hansenii H4651 at temperatures cultivated-tion 15 and 20 ° C. Out D. hansenii yeast biomass H4651 exceeds the yield of biomass when cultured yeast D. hansenii strains H433 and H18–3.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>меласса</kwd><kwd>дрожжи Debaryomyces hansenii</kwd><kwd>культивирование</kwd><kwd>β – фруктофуранозидаза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molasses</kwd><kwd>yeast Debaryomyces hansenii</kwd><kwd>cultivation</kwd><kwd>β – fructofuranosidase</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abranches J., Valente P., Nóbrega H.N., Fernandez F.A.S. et al.
