A new alkalophilic isolate of Bacillus as a producer of cyclodextrin glycosyltransferase using cassava flour.
Cyclodextrin glycosyltransferase (CGTase) catalyzes the conversion of starch into non-reducing cyclic sugars, cyclodextrins, which have several industrial applications. This study aimed to establish optimal culture conditions for β-CGTase production by Bacillus sp. SM-02, isolated from soil of cassava industries waste water lake. The optimization was performed by Central Composite Design (CCD) ...
متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولCrystallographic analysis of maltohexaose-producing amylase from alkalophilic Bacillus sp.707
Preparation and crystallization G6-amylase from alkalophilic Bacillus sp.707 was expressed by Bacillus subtilis 207-25. The enzyme was crystallized by the hanging drop vapor diffusion method using the reservoir solution containing 50% (v/v) 2methylpentane-2, 4-diol, 100 mM Tris-HCl (pH 8.5) and 200 mM ammonium phosphate. Calcium chloride and sodium chloride were added to final 1 mM in the drop ...
متن کاملCyclodextrin glycosyltransferase production by new Bacillus sp. strains isolated from brazilian soil
Three strains of Bacillus sp. (BACRP, BACNC-1 and BACAR) were isolated from soil adhered to cassava husk. CGTase specific activity for the three isolated strains was higher when cultivated at 40°C. Potato starch, cassava starch, maltodextrin and glucose were used as carbon source and growth temperatures varied from 25 to 55°C. The three isolates presented higher CGTase specific activity when cu...
متن کاملMolecular Identification and Characterization of Bacillus sp. NIGAB-1 for Phenol Degradation Under Saline Conditions
Background: Phenol is an aromatic pollutant in industrial wastes that in combination with salts is highly toxic for all forms of life. Phenol elimination is the foremost challenge to meet the goal of pollutant-free environment. Objective: The present study was carried out to isolate phenol degrading bacteria which can degrade phenol under saline conditions and...
