Understanding the relationships between biochemical contents and morpho-phenological aspects of a plant during life cycle would be helpful for doing precise agricultural practices through its cultivation. In the present study, various biochemical parameters were evaluated in relation to bulb storage, shoot growth and florogenesis in Iranian lily (Lilium ledebourii var. Kelardasht Salehi1). Ten ...

Problem statement: This study reported the purification and characterization of a novel highly thermostable alkaline amylase from a newly isolated Bacillus strain HUTBS71. Approach: The enzyme was purified using ammonium sulfate precipitation, ion exchange and gel filtration chromatography. Results: Maximum amylase activity (72 U mL) was obtained at 100°C after 10 min of incubation. The enzyme ...

Th e paper presents numerical comparison of two methods of estimation of nonallelic interaction of QTL eff ects. In the fi rst method we assume that we observe only the plant phenotype, while in the second method we have additional information from the molecular markers observations. In this paper we analysed phenotypic data on 120 barley doubled haploid lines, derived from cross Clipper × Saha...

diabetes mellitus is one of the most common endocrine diseases and its type ii is the major form of diabetes, accounting for 90% of cases worldwide. the inhibition of carbohydrate hydrolyzing enzymes such as ?-amylase can be an important strategy in the control of blood glucose levels in patients with type ii diabetes. in this investigation, three morus species, m. alba, m. alba var. nigra and ...

The enzyme amylase was shown to be present in extracts prepared from both house dust and spent growth medium used in the culture of the mite Dermatophagoides pteronyssinus. In dust, it was shown to correlate with both mite counts and concentrations of the faecally derived mite allergen, Der p I. Mite amylase was isolated from the culture medium and shown to be a single chain protein with a mole...

objective(s):one strategy for the treatment of diabetes is inhibition of pancreatic α- amylase. plants contains different chemical constituents with potential for inhibition of α-amylase and hence maybe used as therapeutic. materials and methods: urtica dioica and juglans regia linn were tested for α-amylase inhibition. different concentrations of leaf aqueous extracts were incubated with enzym...

Five fungal isolates were screened for the production of "-amylase using both solid-state and submerged fermentations. The best amylase producer among them, Aspergillus niger JGI 24, was selected for enzyme production by solid-state fermentation (SSF) on wheat bran. Different carbon and nitrogen supplements were used to enhance enzyme production and maximum amount of enzyme was obtained when SS...

Porcine pancreatic alpha-amylase (PPA) was allowed to react with herbal extracts containing rosmarinic acid (RA) and purified RA. The derivatized enzyme-phytochemical mixtures obtained were characterized for residual amylase activity. These in vitro experiments showed that the amylase activity was inhibited in the presence of these phytochemicals. The extent of amylase inhibition correlated wit...

Alpha-amylase is a very important enzyme in the starch conversion process. Most of the α-amylases are calcium-dependent and exhibit poor performance in the simultaneous saccharification and fermentation process of industrial bioethanol production that uses starch as feedstock. In this study, an extracellular amylolytic enzyme was purified from the culture broth of newly isolated Talaromyces pin...

in this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (znfe2o4@sio2-nh2) is reported. for doing so, at first, the magnetic nanoparticles of znfe2o4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (teos) and 3-aminopropyltriethoxy silane (aptes) were used for modification of znfe2o4 nanoparticles wi...
