Plant Growth Promoter Rhizobacteria (PGPR) is soil bacteria that can live on, in or around plant tissue and promote plant growth by many mechanisms that include a biological control of plant pathogens. Indeed, PGPRs have a protective effect through several modes of action such as antagonism, competition, production of hydrolytic enzymes and biofilm formation. Moreover, the use of PGPRs as biocontrol agents is very harmonious with the environment and therefore represents a good alternative to the use of chemicals in agriculture. This review is presented as a general bibliographical synthesis on the different aspects of PGPRs and their biocontrol potential.

The aim of this study is to the estimation of the nutritive values, phytochemical study and the antioxidant and anti-inflammatory activities of ethyl acetate, tannins and crudes extracts from the aerial part of Calligonum comosum L’Hér. Which grow in South East of Algeria. According to the results obtained from the estimation of nutritive value, the plant is rich in proteins and lipids and very poor in carbohydrates. The results also showed a difference in the content of polyphenols and flavonoids. The crude extracts were high in polyphenols content in the ethanol extract 170.74±5.8 mg EAG/g Extract, and the best value of flavonoids in methanol extract 28.22±0.25 mg QE/g Extract. Chromatographic analysis by HPLC of methanolic extract has identified four phenolic compounds out of 38 peaks as: Gallic acid, Chlorogenic acid, Caffeic acid and Vanillic acid. The antioxidant activity was evaluated by three tests, the results of the DPPH• test, showed that methanol extract had the best scavenging than the other extracts (IC50: 2.09±0.02 μg/ml), But, in the hemolysis test, the values of the percentage of hemolysis were approximately the same at concentration 1 mg/ml between the extracts and standard used. In the reducing power test, its results showed that the tannins extract had the highest reducing power 79.17±5.22 μg/ml at Abs700nm=0.5. As for anti-inflammatory activity, the methanol and flavonoids phase ethyl acetate extracts showed the best inhibitory effect against protein denaturation compared to other extracts. The effects were estimated 3.14mg E Diclofenac/mg Extract.

As part of this contribution, we will illustrate the effectiveness of the Bayesian approach in estimating durations; we suggest a new definition of the Kaplan Meier Bayesian estimator based on a stochastic approximation under an informative prior. For this reason, based on the lognormal distribution, we have unconjugated a priori distributions. This method of processing makes it possible to assume that the use of the a priori data with the various suggested methods is sensitive to the choices of the parameters added.

Heavy metal and microbial pollution of the environment are linked to the increasing prevalence of diseases worldwide. Accordingly, this study assessed the safety of urban soils in Lagos, Nigeria, with regard to the levels of lead (Pb), nickel (Ni), cadmium (Cd), copper (Cu), chromium (Cr), zinc (Zn), and microorganisms. Soil samples were collected from Iwaya, Makoko, and Ilaje areas of the city and subjected to atomic absorption spectroscopy (AAS) and microbiological examinations using standard protocols. The mean values obtained for the heavy metals and microorganisms were compared with the World Health Organization (WHO) permissible limits. The average daily oral ingestion (ADOI), average daily dermal ingestion (ADDI), and the hazard quotient (HQ) of the heavy metals were also calculated. The AAS indicated that the soils in the three areas contained non-permissible levels of the evaluated heavy metals, except Cu and Cd. The microbiological examinations also showed that the soils contained abnormal levels of heterotrophic bacteria (HB), hydrocarbon utilizing bacteria (HUB), heterotrophic fungi (HF), and hydrocarbon utilizing fungi (HUF). The ADOI of the heavy metals in the three areas were above the recommended levels, while ADDI were normal. Moreover, the HQ of oral ingestion of each heavy metal except Cr was greater than one, while the HQ of dermal ingestion of the heavy metals was less than one. These findings suggest that the soils could predispose the residents in the areas to diseases. Thus, there is a need for regular environmental sanitation and environmental pollution control in the areas, and personal hygiene.

The nutritional richness of fruits and vegetables makes them an ideal target for microorganisms, causing in particular soft rot. The microorganisms responsible for this pathology are generally found in the environment, and are endowed with a very important enzymological power, the main action of their pathogenicity. These enzymes, which allow the degradation of the plant cell wall, allow them to cross the protective wall of the plant, causing a liquefaction of tissues, whose environmental conditions as well as transport and storage conditions favour the development of these phytopathogens. A better understanding of spoilage microorganisms and the characteristics of spoilage should allow the development of new conservation and protection technologies and reduce the loss of vegetables due to spoilage. This review summarizes the main literature data on soft rot, and the diversity and mode of action of the main microbial causal agents.

The aim of this study was to prepare magnesium oxide nanoparticles (MgONPs) using aqueous leave extract of Ocimum basilicum L. and to evaluate their acute toxicity. The characteristics of biosynthesized MgO powder was analyzed by UV–Vis spectroscopy, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The acute toxicity test of MgONPs was applied in Wistar albino rats with different concentration. Results showed that the broad bell-shaped spectrum band was obtained by UV–Vis spectroscopy indicates the formation of MgO. The SEM images provided further insight into the shape and size of MgO which to be ranging under 440 nm. Fourier transform infrared (FTIR) spectroscopy detected the vibration of the Mg─O bond that indicate the presence of magnesium oxide nanoparticles (MgO). In this study, the toxicity test showed no mortality or behavioral change in low dose of MgNPs (250 mg / kg b.w) but we observed that 50% of rats have died when treated with high dose of MgNPs (500 mg/kg b.w.). This study confirmed that aqueous extract of Ocimum basilicum L. has potential properties as biocatalyst for the biosynthesis of MgONPs without any toxicity under dose 250 mg/kg in rats.

In this study, the antioxidant and antimicrobial activities of Echinophora spinosa were investigated. Antimicrobial activity of methanol extracts obtained from Echinophora spinosa was examined using the disc diffusion method. Antioxidant activity of the methanol extracts was examined using the stable 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging test. Methanol extract of ripe fruits of E. spinosa showed highest total phenolic content (69.17 ± 1.2 µg GAE/mg extract) and the major flavonoid contents (12.122 ± 0.44 µg QE/mg extract) was found in leaves of the plant. In disk diffusion antimicrobial assay, E. spinosa manifested broad spectrum of activity. The largest capacity to neutralize DPPH radicals was found for ripe fruits methanol extract of E. spinosa plant. The results shows that the various parts of E. spinosa extracts promising antioxidant and antimicrobial activities have potential bioactivities due to high content of phenolic and flavonoid compounds.

A field experiment was conducted on a private farm in El Oued State of Algeria to study the efficiency of using Fertil Verde as a fertilizer by foliar spry on hot pepper seedlings. The treatment by Fertil Verde increased all growth. The increase was significant in the number of main and secondary stems, the size of the leaves, and the weight of the dry leaves. While, the weight of the wet leaves did not significantly increase. Moreover, the use of Fertil Verde has led to a significant increase in the yield qualities of the plant: the weight and shape of the fruits, fresh yield of the plant, the content of pigment, and the size of the plant. Thus, the combination of fertilizing is common and Fertil Verde is a promising low-cost option in the production of high yields.

The main objective of this study is to determine the effect of food intake of date syrup on the treatment of anemia.First, we used 3 samples of dates from different regions for the preparation of the syrup. We have studied certain criteria (physical, chemical, biochemical, microbiological); where the results showed that the prepared date syrup has a good hygienic quality, and of remarkable nutritional quality due to its ideal content with many properties, such as carbohydrate and protein content.To evaluate the anti-anemic properties of date syrup in rats, anemia is induced by a food having an iron deficiency. Date syrup, prepared from Djamaa dates, was administered by gavage of anemic rats at doses of 1000 mg / kg / day and 2000 mg / kg / day resulting in an increase in hemoglobin, red blood cell count, hematocrit and serum iron. Thanks to the results obtained, date syrup can be classified among the foods that help fight iron deficiency anemia.
本研究的主要目的是确定食用枣糖浆对治疗贫血的影响。首先，我们使用了3个来自不同地区的枣子样品来制备糖浆。我们学习了一些标准(物理、化学、生化、微生物);结果表明，所制备的红枣糖浆具有良好的卫生品质，其碳水化合物和蛋白质的含量理想，具有显著的营养价值。为了评估枣糖浆在大鼠中的抗贫血特性，贫血是由一种缺铁的食物引起的。用Djamaa枣制成的枣糖浆，分别以1000 mg / kg /天和2000 mg / kg /天的剂量灌胃贫血大鼠，导致血红蛋白、红细胞计数、红细胞压积和血清铁增加。由于获得的结果，枣糖浆可以被归类为有助于对抗缺铁性贫血的食物之一。
