“…Since then, this species has rapidly expanded its area to Bulgaria, Czech Republic, France, Germany, Poland, Slovakia, Switzerland, UK (Braun and Cook, 2012), Slovenia (Milevoj, 2004), Ukraine (Heluta et al, 2009) and Romania (Fodor and Vlad, 2013). Recently, it was also reported in Asia, specifically Korea (Cho et al, 2014) and Turkey (Erper et al, 2018), parasitizing C. bignonoides, whereas in Thailand was noted on Eucalyptus camaldulensis Dehnh. (Meeboon and Takamatsu, 2017).…”

Erysiphe elevata is a North American fungus that causes the powdery mildew of Catalpa species. The present study brings new data on the spread of this species in Romania, and given its invasiveness in Europe, the study evaluates the incidence and intensity of the powdery mildew caused to Catalpa bignonioides (Southern catalpa). In 2017, 12 North-Estern Romanian cities where C. bignonioides had been planted in green spaces were investigated. The results have shown that the pathogen is widespread in the North-Estern part of Romania, accompanying the host plant in all of the localities investigated. In addition, the high frequency of the disease, confirms the invasiveness of E. elevata, most affected being the trees that were planted along streets and in public squares. A specimen of E. elevata was sequenced and the BLAST results revealed that it is identical to samples from France and Korea.

The article continues a series of critical reviews of the species composition of powdery mildew fungi (Erysiphaceae, Helotiales, Ascomycota) of Ukraine and their distribution within the country. This article deals with species of the section Microsphaera of the genus Erysiphe. These species are distinguished by fruiting bodies that have non-mycelioid appendages with dichotomously branched apices. A list of 36 species of the section Microsphaera recorded in Ukraine with their distribution by regions is provided, as well as a key for their identification. The most common species frequently occurring in many regions of Ukraine are E. alphitoides, E. astragali, E. berberidis, E. divaricata, E. ehrenbergii, E. euonymi, E. ornata var. europaea, E. palczewskii, E. syringae-japonicae, and E. trifoliorum. Other species, such as E. baeumleri, E. elevata, E. euonymicola, E. friesii, E. grossulariae, E. hyperici, E. hypophylla, E. ornata var. ornata, E. penicillata, E. pseudoacaciae, E. robiniae, E. syringae, E. tortilis, E. vanbruntiana, and E. viburni, were recorded less often. Erysiphe azaleae, E. begoniicola, E. corylacearum, E. deutziae, E. gorlenkoi, E. guarinonii, E. magnifica, E. magnusii, E. platani, E. rayssiae, E. russellii, and E. symphoricarpi are known only from some localities. A number of species are invasive fungi mostly recorded in Ukraine relatively recently, within the last hundred years. Of them, E. alphitoides, E. palczewskii, E. syringae-japonicae, and E. vanbruntiana have become common species in Ukraine. Erysiphe azaleae, E. elevata, and E. platani can massively develop in certain regions or localities. The recently registered E. corylacearum is apparently becoming widespread in the Carpathians, E. ravenelii and E. symphoricarpi at present frequently occur in Kyiv. Some species, such as E. begoniicola, E. deutziae, E. euonymicola, E. guarinonii, E. magnifica, and E. russellii, are known from a few localities; however, in Kyiv magnolias are commonly infected by E. magnifica. At the same time, the North American species E. syringae has disappeared in Ukraine since the East Asian fungus E. syringae-japonicae started to spread on lilac. The indigenous fungus E. robiniae has also ceased to occur on Caragana arborescens, being completely replaced by the East Asian species E. palczewskii.

“…Generally, the design achieved best result in screening and optimization processes [15]. The main advantage was able to analyse the effects of each factor towards the response that varies with different levels and interaction effects of different factors could be verified using design of experiment only compared to one-factor-at a time experiment [16]. Thus, the software will reduced the number of experiments, time, and overall processes costs in order to obtain a good response.…”

The present study focusing on the performances of advanced oxidation process by using ozonation method towards Methyl Orange based on the efficiency of colour removal and Chemical Oxygen Demand (COD) removal. Factorial design with response surface methodology (RSM) was used to evaluate the interaction between operational conditions, such as pH, initial concentration, contact time and persulfate dosage to obtain the optimum range conditions using a semi-batch reactor. The range of independent variables investigated were pH (3-11), initial concentration (100-500mg/L), contact time (10-50min) and persulfate dosage (20-100mM) while the response variables were colour removal and COD removal of Methyl Orange. The experimental results and statistical analysis showed all the parameters were significant. Thus, from this findings, optimization of operational conditions that had been suggested from the ozone/persulfate RSM analysis were (pH 3, 100 mg/L, 50min, 60mM) that would be produced 99% Colour Removal and 80% COD Removal and help in promoting an efficient ozonation process. The effect list data that showed the most contributed effects to increase the percentages of colour removal were pH and persulfate dosage whereas the contact time and initial concentration had the highest positive effects on the COD removal. Other than that, the interaction between pH, contact time and persulfate dosage were found to be the most influencing interaction. Therefore the least influencing interaction was interaction between persulfate dosage and pH. In this study, the correlation coefficient value R2 for colour removal and COD removal of Methyl Orange were R2= 0.9976 and R2= 0.9924 which suggested a good fit of the first-order regression model with the experimental data.
