ABSTRACT One of the factors that may affect and limit production in eucalypt plantations is attack defoliating insects. Among those, brown caterpillar, Thyrinteina arnobia (Stoll, 1782) (Lepidoptera: Geometridae), stands out for being major pest Eucalyptus spp. Brazil. Thus, present study aimed to investigate food consumption T. arnobia, its native host, guava (Psidium guajava L.), different E....
phenylalanine dehydrogenase (phedh; ec 1.4.1.20) is an important enzyme of amino acid dehydrogenases family that increasingly used as a valuable biocatalyst in neonatal screening kits and synthesis of l-phenylalanine. the goal of this literature was to find a suitable purification method for recombinant bacillus badius phedh by practical comparison between chromatographic and polyvinyl pyrrolid...
background: taq dna polymerase is a very important enzyme for molecular biological studies such as dna amplification and dna sequencing by the pcr. it is a standard enzyme that is used in 90% of molecular biology labs today. the aim of this study was to produce taq dna polymerase enzyme in e. coli by a reliable, practical, simple and low cost method.materials and methods: in this study, the taq...
Background & Objective: In order to enhance the expression of soluble proteins and facilitate their purification and development of multi-functional polypeptide , chimerical recombinant proteins have been invented . The purpose of this study was to construct ctxB-gfp-stxB gene cassette to measure the uptake and excretion of chimerical antigen in future studies. Materials & Methods: After prep...
Coxiella burnetiiis an obligate and gram-negative bacteria causing query fever (Q fever) disease, despite the importance of Q fever, there is no universal vaccine against this disease. Therefore, application of the recombinant subunit vaccines which use Com1 and OmpH as immunogenic proteins can be useful in this regard. To perform the current project, Com1 an...
In a recent paper, De Baets et al. have characterized the fuzzytolerance and fuzzy equivalence relations that a given strict order relation iscompatible with. In this paper, we generalize this characterization by consideringan arbitrary (crisp) relation instead of a strict order relation, while payingattention to the particular cases of a reflexive or irreflexive relation. The reasoninglargely ...
Changes in black tea quality were studied for three subsequent years and in different times of plucking (spring, summer and autumn) in the form of two leaves and a bud. Percentage of waste, total sensory scores, total soluble solid, caffeine, theaflavin, thearobigin, total color and brightness were evaluated in black tea. The data were analyzed in split plot design based on randomized complete ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
