Item A new locality of an invasive Gecko, Cyrtopodion scabrum (Heyden,1827) in Algeria (Squamata: Gekkonidae)(جامعة الوادي - University of Eloued, 2021-06-30) Salah Eddine, Sadine; Choyaib, Bounaba; Mayssara, El BouhissiThe Rough Bent-toed Gecko Cyrtopodion scabrum (Heyden,1827) was recently recorded in Algeria, from the east part of countries. In this note, another new locality of this species in the central Algeria (Ghardaïa region), situated at 450 km west form the last locality, based on one specimen fond in Bord of Sebkhet. C. scabrum is listed as an invasive species and it was reported as a desert species, in our finding it was recorded in an important wetland (Sebkhet El Melah) which is classified in the Ramsar list in 2004, this statement proves once again the ecological plasticity of this species.Item Characterization of endospore-forming bacteria producing extracellular enzymes isolated from the Djurdjura Mountains in Algeria(جامعة الوادي - University of Eloued, 2021-06-30) Merzouk, YAHIAOUI; Khelifa, BOUACEb; Katia-Louiza, ASMANI; Sondes, MECHRI; Hamdi, BENDIF; Mohammed, HARIRe; Bassem, JAOUADIBiodiversity in mountains in Algeria appears scanty and has not been thoroughly investigated. However, the mountain soil has been shown as an almost entire reserve of novel enzymes with interesting properties for industrial and environmental applications. In the present study, thirty bacterial strains were isolated from the Djurdjura Mountains in Kabylia (Algeria) and were studied for their ability to produce enzymes to be possibly used in biotechnological processes such as amylase, caseinase, and chitinase. The characterization of these isolates was carried out using morphological, physiological, and biochemical characteristics. All the data obtained with regards to the phenotypical properties of the isolates, confirmed that the strains belonged to the Bacillus group. In addition, the 16S rRNA gene of the two retained strains KA15 and LK-DZ15 was also amplified and sequenced. Phylogenetic tree was, afterwards, constructed. The nucleotide sequences and blast analyses confirmed that the KA15 and LK-DZ15 strains were closely related to those of the Bacillus altitudinis (accession n°.: MK874318) and Paenibacillus timonensis (accession n°.: MK734103) strains. The presence of amylases, proteases, and chitinases in KA15 and LK-DZ15 isolates are an indicator of their pivotal application in a variety of biotechnological processes.Item Preliminary Phytochemical Screening, Quantification of phenolic compounds, of Plant Extract from Chenopodium quinoa(جامعة الوادي - University of Eloued, 2021-06-30) KADRI, mounira; RAMDANE, Farah; BOUZID, Rachidac; ATTALI, HalimaThe aim of this study was to screening the phytogenic chemical compounds of the seeds of Chenopodium quinoa, obtained from Wilaya of El-Oued. The chemical study showed that the plant contained a number of secondary metabolites, flavonoids, tannins, saponins, steroids and triterpenes, glycosids while the absence of alkaloids and coumarin in Chenopodium quinoa. Folin-Ciocalteau colorimetric were used to determine the total phenolic con-tent (TPC), in the hydroalcoholic seeds extracts. The yield of the methanolic extract was estimated at 36.66%. As for the quantitative content of polyphenols, it is 11.647 ± 1.91µg AGE / mg extrait From this, Chenopodium quinoa is considered a nutritional and therapeutic value because it contains secondary metabolitesItem Influence of leaf extracts and total flavonoids of Rhus tripartita (Ucria) Grande on phytobeneficial bacteria associated with its rhizosphere(جامعة الوادي - University of Eloued, 2021-06-30) Benaissa, Asmaa; Dahbi Lalla, Fatma-Zohra; Tabra Oum, Elhassenea; Djellout, Nadine ChahrazadeThe article deals with the antimicrobial effect of Rhus tripartita (Ucria) Grande leaf extracts and total flavonoids against twelve antagonists Plant Growth Promoting Rhizobacteria of its rhizosphere, characterized in a previous study. The aim of this study is to demonstrate that leaves through their decomposition in the soil, may affect the distribution of bacterial communities in the rhizosphere. Leaves extracts were performed with distilled water, alcohol, methanol, hexane and chloroform as solvent and diluted in concentrations of 0.001, 0.01 and 0.1 mg/mL. The extraction of total flavonoids was carried out from leaves’ methanolic extract. The antimicrobial effect of the extracts was evaluated by the agar diffusion method and the determination of the minimum inhibitory concentration was carried out on a liquid medium. Alcohol, chloroform and methanol extracts were found to be the most effective on tested strains. The maximum zone inhibition was 18 mm, and the minimum zone inhibition was 7 mm. Rt 1: Bacillus licheniformis appears to be the most sensitive to all extracts. In contrast, Rt 7: Bacillus megaterium, seems to be the less sensitive strain. On the other hand, total flavonoids had a significant effect on 25% of the strains tested, mainly Bacillus genus. With a broad antimicrobial spectrum, the Rhus tripartita leaf extracts can be considered as a control agent for the distribution of the bacterial community in the rhizosphere. Therefore, our work showed that the plant could influence the bacterial diversity of its rhizosphere through its leaves.Item Ethnobotanical survey of herbal remedies traditionally used in ElHammadia (Southern region of the province of Bordj Bou Arreridj, Algeria)(جامعة الوادي - University of Eloued, 2021-06-30) Hamdi, BENDIF; Mohammed, HARIR; Merzouk, YAHIAOUI; Nabila, SOUILAHd; Fatima Zohra, HECHAICHI; Mohamed, DjamelMIAR; Ifriqya, MEDILAThis work is devoted to the study of medicinal plants in the southern region of BordjBouArreridj (communes of the Daïra of El Hammadia), and their different uses in traditional medecine. A series of surveys were conducted in the study area with inhabitants and herbalists, to acquire more informations about the therapeutic uses of medicinal plants practiced by the local population. The analysis of the results allowed us to identify 78 species belonging to 36 families, the most represented are: Apiaceae (13.92%), Lamiaceae (12.65%), Asteraceae (11.39%) and Liliaceae (5.06%). The most commonly parts used from these plants are respectively: the leaves (34.21%), the stems (17.54%), the fruits (12.28%), the roots (10.52%) and the seeds (8.77%). Medicinal plants are prepared and used as powder, infusion, especially as decoction and poultice. The most used is the decoction. The main common health problem treated are; digestive disorders (29.81%), respiratory disorders (10.55%), skin inflammations (9.17%), urinary inflammations (8.25%), liver diseases (6.88%) and neurologic problems (6.42%). El Hammadia has good ethnobotanical potential of medicinal plants. This study is the first contribution to the ethnobotany of this region. We have gathered from this province some considerable knowledge about local medicinal plants for treating diseases.Item Ecology and behavioral response of Ruddy Shelduck (Tadorna ferruginea) in the wetland complex of Oued Righ valley (Algerian Sahara).(جامعة الوادي - University of Eloued, 2021-06-30) Yassine, NOUIDJEM; Asma, ZOUBIRIa; Sakina, MEROUANIa; Fateh, MIMECHEThe wetland complex of Oued Righ valley accommodates a population of Ruddy Shelduck (Tadorna ferruginea) between 2012 and 2014, the total reached 80 individuals in the Lake Hamraia where the species wintering. The analysis of the diurnal time budget of wintering populations revealed the role of feeding area delivery for this species and they devoted their day time to feeding (51.2%), sleeping (18.8%), followed by swimming activity (6.3 %), and courtship activities with flying (2.03%) which often occurs after disturbances caused by human or by Marsh harrier (Circus aeruginosus). It is interesting to study the behavior of these ducks in Saharan bioclimatic area and follow the phenology and characteristics in order to preserve the biodiversity in this region.
