Two extracts of 50 mg.ml-1 Agaricus bisporus alcoholic and aqueous were used in order to study their effect against two pathogenic bacteria. Salmonella typhi and Staphylococcus aureus strains isolated from chicken and minced meat samples respectively, then identified according to biochemical tests. Antibacterial activity of Agaricus bisporus extracts (alcoholic and aqueous) was studied by agar well diffusion method. The results exhibited that aqueous mushroom extract has no effect against the two tested bacteria, while alcoholic extract of mushroom affect against the two tested bacteria and the effect against S. aureus was more than that against Salmonella typhi and the zone of inhibition was 15 mm and 9 mm respectively. The ethanol alcohol 96% and water were used as control. From this study, mushroom extracts especially ethanolic or alcoholic could be used to control the transmission of pathogenic bacteria from food

Alkaloids often had pharmacological effects. The aim at this study is to increase some alkaloids in fenugreek. Callus induction occurred on cotyledon segments 5 mm long. Murshige and Skoog medium (MS) supplied with 1 mg.lˉ¹ of 2, 4 – D and 0.4 mg.lˉ¹ of kinetin was prepared. The best medium maintained callus was using MS medium supplied with 0.5 mg.lˉ¹ 2, 4-D and 0.5 mg.lˉ¹ kinetin. Callus formation was allowed to take place for a period of thirty days in the dark at 25°C±2. Calli were analyzed using high performance liquid chromatography (HPLC).Methanol callus extract showed high concentrations of some alkaloids compared to the methanol extract of cotyledons. For increasing, the concentration of secondary metabolites, NaCl was added at concentrations 0, 1, 1.5 or 2 g.lˉ¹, sorbitol at concentrations 0, 7, 8 or 9 g.lˉ¹. NaCl at 2 g.lˉ¹ led to significant increase in trigonelline reaching 1354.72 µg per 100 mg fresh weight of callus. NaCl at 1g.lˉ¹ increased choline and carpaine reached 400.82, 483.92 µg.mlˉ¹ per 100 mg respectively. Treatment with 9 g.lˉ¹ sorbitol increased trigonelline and carpaine reached 1666.41, 742.67 µg per 100 mg respectively, while treatment 8 g.lˉ¹ sorbitol significantly increased in choline recorded 588.87 µg per 100 mg.

luxS and rpoS genes were involved in the regulation of some biological processes, which interfere with virulence of Serratia marcescens and Enterobacter cloacae bacterial species sequentially. luxS have an important activity in Quorum Sensing (QS) processes, but rpoS interfere with tolerance and resistance processes toward stress conditions correlating with its virulence. The study aimed to detect rpoS presence in E. cloacae and luxS gene presence in S. marcescens separately isolated from 16 leukaemia patients (4 of S. marcescens and 12 of E. cloacae), who characterised with bacteraemia by using primers designed for this purpose by using PCR technique. The results showed that all of the bacterial isolates of S. marcescens contain luxS gene, while no one of E. cloacae isolates show positive results for rpoS gene. The study concluded that S. marcescens has high virulence as a result of luxS presence, which controls Quorum sensing and prodigiosin formation and affecting host immunity. Moreover, the negative results of rpoS gene can be explained according to two possibilities: the gene can be found in the isolates with a copy differ from the registered sequences of the rpoS gene, or the gene did not present in those isolates with presence of alternatives offset its activities

Ponceau 4R(E124) is azo dye that is mostly used in some of food products such as soft drinks, beverages, jelly and ham. A simple and sensitive procedure is established for the determination of ponceau 4R using cloud point extraction (CPE). In order to get the optimum conditions for ponceau 4R extraction, various analytical factors such as pH media, nonionic surfactant TX-114 or Brij-56, cationic surfactant CPC and equilibration temperature was investigated. The linearity of calibration graph was above the range of 0.05-1.7 µg ml-1. The LOD and LOQ using TX-114 were based to be 0.025, 0.075 µg ml-1 whereas for Brij-56 were found as 0.062, 0.187 µg ml-1 respectively.

Fructan is a kind of biopolymer produced from plants, fungi, yeast and bacteria. It is classified as prebiotics food and enhanced the growth of probiotics bacterial strains which improves the health of the individual. This article aimed to study the production and extraction of fructan from Pseudomonas putida isolated from food samples and study the effect of fructan on the viable cell number of Lactobacillus acidophilus. The results showed that Pseudomonas putida have the ability to produce fructan when cultured on production medium (YPS), fructan exhibited as white powder when extracted from YPS and the amount of fructan was 3.6 mg/100 ml, also the results showed that fructan can increase the viable cell number of Lactobacillus acidophilus when added to MRS. FTIR analysis of fructan produced from Pseudomonas putida revealed that the functional groups found in chemical structure of fructan, which it was (C-O, C-H, O-H and C=O).

In this article, a Legendre wavelet- Chebyshev wavelet spectral collocation method is proposed for solving fractional order space-time Burger's equation with the Legendre wavelet and Chebyshev wavelet operational matrices of fractional derivatives. The fractional derivative is described in the Caputo sense. The proposed method is based on Legendre wavelet-Chebyshev wavelet for space and time variables respectively. This method will reduc the problem under consideration to the solution of nonlinear algebraic equations. In order to confirm the efficiency of the proposed method, two numerical examples are implemented and comparing the numerical solution with the exact one, as well as, of other methods in given literatures, we demonstrate the high accuracy and efficiency of the proposed method.

The fractional derivative is described in the Caputo sense. The proposed method is based on Legendre wavelet-Chebyshev wavelet for space and time variables respectively. This method will reduc the problem under consideration to the solution of nonlinear algebraic equations. In order to confirm the efficiency of the proposed method, two numerical examples are implemented and comparing the numerical solution with the exact one, as well as, of other methods in given literatures, we demonstrate the high accuracy and efficiency of the proposed method.","PeriodicalId":14922,"journal":{"name":"Journal of Al-Nahrain University-Science","volume":"38 1","pages":"121-127"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83250866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
