This study was aimed to test four types of different plants for the purpose of selecting the optimal plant as a source of the amylase enzyme, including wheat, barley, rice, and potatoes. Among these plants, wheat was selected as the best plant source for enzyme extraction because it possessed the highest effectiveness of the enzyme specific activity (3.0 U/mg protein). Furthermore, sodium acetate buffer (0.2 M, pH 6.0) was determined to be the optimal extraction buffer with a 1:5 (w:v) ratio after 75 min, and it provided 68 U/mg protein. The enzyme was concentrated with sucrose before being purified by gel filtration chromatography using Sephadex G-150. The results demonstrated a 1.8-fold increases in final purification folds wit

Freshwater algae (Chlorophyceae-except Zygnematales) were collected from 18 sites (12 springs and 6 streams) in Shaqlawa district within Erbil Province, Kurdistan Region of Iraq from September-2019 to August-2020. Aim of this study isolation and identification new algal species. 27 new algal genera with 40 species records at first time in Kurdistan Region and others provinces of Iraq, which include the following, Scenedesmus considered the most abundance than others algae which seven species identified followed by genus of Chlamydomonas, genus of Chlorophyceae, genus of Characium with three species for each one recorded, but genera Geminella have two species, finally the remaining gene

This study was aimed to examine and detect the total flavonoid presence from the crude extract use in phytochemical test and HPLC device, and detecting  on both extract by UV-spectrophotometer. The objective of this study for inhibition the pyocyanin pigment that produce by pseudomonas aeruginosa by use Marticaria chamomilla crude and flavonoid extract.  The extraction of chamomile was accomplished by methanol 80%, where different concentrations and dilutions of the crude and flavonoid extract and used as anti-virulence factor. 130 clinical samples of burns and wounds where collected from patients in the medical city hospital. The result showed that 44 isolates where identified as  P.aeruginos

Meropenem (MER) antibiotic is removed from an aqueous solution using Mg-Al-layered double hydroxide (Mg/Al-LDHs) which serves to functionalize the principal object of enquiry in this paper–sunflower husks (SFH).  The former sample demonstrated a 51% removal of MER while the latter demonstrated a 67% removal of MER. One of the areas explored was the impact of the rise calcination temperatures resulted in a concurrent increase in the surface area and porosity of LDHs which, in turn, provoked a heightened removal efficacy of MER at calcination temperatures between 300 °C and 350 °C. Nonetheless, LDHs experienced structural deformation and thus, diminished removal efficacy of MER when the ca

The current research dealt with a comparative taxonomic study of the two types Chenopodium album L. and Chenopodiastrum murale L. at Baghdad , This research was included a cytological study by calculating the chromosome number by sequence n=27,9. and studying the micro-morphological characteristics of the seeds and fruits of the two types, in addition to the surface covering in the leaf part. All phenotypic characteristics of the seeds were studied by scanning electron microscope (SEM) and Light microscope (LM) in terms of shape, colour, dimensions Seed size were measured by the program digmizer , as well as the configuration  of the seeds surface , The seeds of Ch.albu

This experiment was aimed to evaluate and compare the effects of adding natural extracts (clove, Mentha and thyme) with synthetic BHT on some physiochemical, microbial, and sensory characteristics of lamb patties stored at 4 Cº for 12 days. Results indicated that there’s a steady rise (P<0.01) in oxidative rancidity, microbial and pH with the increasing time of storage. Also, a significant (P<0.01) reduction in TBA, microbial and pH was observed in patties treated with clove, thyme, mentha and BHT as compared with untreated samples. It was found that adding natural extracts is more effective in inhibiting microbial count than did BHT. The highest score of overall acceptability was n

Optimal growth of shrimp and harvest in a pond is strongly influenced by water quality because this is a common thing but it cannot be denied that it is also an important thing. The combination of physicochemical parameters and biological indicators has become a classic way of studying water quality. Phytoplankton is a bioindicator that affects the productivity of vannamei shrimp in ponds. Currently, shrimp farming activities are intensive. This study aimed to analyze the diversity and abundance of phytoplankton and water quality in vannamei shrimp ponds. The research objective was achieved by calculating the abundance, diversity index, evenness index, and plankton dominance index in ponds. The results of the study were that the

 A Restricted Selection Index was constructed to genetically evaluate animals using a dataset composed of body weights of Shami kids at the ages of birth, weaning, and 6-month. The variance-covariance matrix (VCV) was generated and used to estimate genetic parameters for the index construction after adjusting the fixed effects; year, birth month, kid sex, type (single, twin or triplet) of birth, doe age, weights at kidding (KW), birth (BWT) and weaning (WWT) as covariates. General Linear Model and Restricted Maximum Likelihood methods were used to estimate BLUE for fixed effects and variance components for random effects, respectively. BW was 3.6

This work was conducted to study the association of variations in the VLDLR gene and mRNA expression in the liver and the ovary of local Iraqi hens with some productive and blood traits. The VLDLR gene variations were studied using blood samples of 173 pedigreed hens, 47 weeks old while the expression was studied using tissue samples of the ovary and liver in 30 pedigreed hens, 60 weeks old. Genotypic and allelic frequencies, production traits, and biochemical serum blood were investigated. The results showed that the genotypic and allelic frequencies of the VLDLR in 173 chickens did not agree with Hardy-Weinberg equilibrium (P<0.0307). The genotypic frequencies were 94.7 and 5.3% for both GG and GT genotypes respectively, whi

This study was conducted to investigate certain characteristics of the purified Phenylalanine ammonia lyase (PAL). The results revealed that the molecular weight was 180 kDa by gel filtration and Native-PAGE. The optimal pH and temperature for enzyme activity were 7 and 40 °C respectively. The enzyme activity was stable against pH values range of 6-8. The enzyme retained 79% of its total activity after incubation for one hour at 50 °C and retained 7% (lost 93%) of its activity at 70 °C. The entire activity was completely lost when the enzyme was incubated for 1 hour at temperatures over 70 °C. Carbohydrate content of the purified enzyme was estimated to be 24.61%. Km, Kcat and Vmax were estimated with phenylalanine as substra

There is an elevated need for novel antimicrobial preservatives in the food industry, and hydrolysis of waste products from the same sector has for decades been viewed as a potential source of these. In the current study we have purified bovine whey protein using size-exclusion chromatography (SEC), and hydrolyzed it by trypsin, pepsin, alcalase, savinase, and neutrase at different times 30, 60, 120, 240, and 300 min. The highest active time hydrolysate was subsequently fractionated by SEC, monitored for antibacterial and antioxidant activities, and characterized using UHPLC-MS/MS. Alcalase and savinase displayed higher degree of hydrolysis, higher antibacterial activity in their hydrolysates at 60 and 30 min, respectively compar

It was using histological stains and histological chemical techniques. The results showed that the Ileum was relatively long, so it characterized into two parts: an anterior part and a posterior part. The results showed that the mucous layer in the two parts consisted of villi that appeared conical in the anterior region and conical to a triangle in the posterior part, and the villi were more numerous and longer in the anterior part. The villi covered with a simple columnar epithelial tissue containing goblet cells in the two regions, but the goblet cells were significantly more
