Objective: Analyze the production of polyhydroxyalkanoates (PHA) by Bacillus subtilis sp., in submerged culture using pear residues as a carbon source.
 Design/methodology/approach: The consisted residue flour concentrations 5 and 15 % for 72 h. Reducing sugars, biomass, pH, protein, pHA extraction quantification were analyzed during submerging cultivation subtilis
 Results: results s...
BACKGROUND The mechanism of hypoglycemic and hypolipidemic activities of Pyrus biossieriana Buhse leaf extract (PbBLE) and its phytochemical component arbutin, have not been well determined. The present study was performed to understand the hypoglycemic activity mechanisms of pbBLE and arbutin more clearly. METHODS In vitro enzymatic carbohydrate digestion with PbBLE and arbutin was assessed ...
Experiments have been carried out with field-grown pear trees to investigate the effect of iron chlorosis on the composition of the leaf apoplast. Iron deficiency was associated with an increase in the leaf apoplastic pH from the control values of 5.5-5.9 to 6.5-6.6, as judged from direct pH measurements in apoplastic fluid obtained by centrifugation and fluorescence of leaves incubated with 5-...
As one of the Ca2+ sensors, calcium-dependent protein kinase (CPK) plays vital roles in immune and stress signaling, growth and development, and hormone responses, etc. Recently, the whole genome of apple (Malus × domestica), pear (Pyrus communis), peach (Prunus persica), plum (Prunus mume) and strawberry (Fragaria vesca) in Rosaceae family has been fully sequenced. However, little is known abo...
خصوصیات رویشی و زایشی سیزده رقم بومی کلکسیون ملی بر اساس دستور العمل ملی آزمون های تمایز، یکنواختی و پایداری ( dus ) ارزیابی شد. در بین صفات رویشی مورد نظر به ترتیب 5، 9 و 13 صفت به شکل درخت، شاخه های یکساله و برگ تعلق داشتند که 4، 5 و 9 صفت از گروه های فوق دارای تنوع بودند. از بین 11 و 29 صفت زایشی مربوط به گل و میوه نیز به ترتیب 9 و 21 صفت دارای تنوع متوسط تا خیلی زیاد بودند. در بین صفات عموم...
Despite the increasing interest in organic products, knowledge about how different levels of fertilization affect nutritionally relevant components is still limited. The concentration of polyphenols and the activity of polyphenoloxidase (PPO), together with the content in ascorbic acid, citric acid, and alpha- and gamma-tocopherol, were assayed in conventional and organic peach (Prunus persica ...
