Biofertilizers or biological fertilizers maintain soil fertility by fixing atmospheric nitrogen, solubilizing P and K, producing plant growth substances and antibiotics as well as biodegradation of organic matter in the soil that enriches the root rhizosphere. Microbial biofertilizers are eco-friendly and less expensive alternatives to chemical fertilizers. The key components of healthy soil are populations of plant growth promoting rhizobacteria (PGPR) which play multiple beneficial and ecological roles in the rhizosphere soil. PGPR colonizes rhizosphere or plant roots, resulting in phytostimulation, biofertilization and biocontrol either directly and/or indirectly. Another important role of PGPR is its ability to decontaminate soils through a process called soil bioremediation. Recently, the known rhizobacteria environmentally friendly biofertilizers for sustainable agriculture are those belonging to Brevundimonas spp., which play a significant role in improving crop production and soil health

The impact of exposing significant mouse organs to cerium oxide nanoparticles (CeO2 NPs) has received considerable attention in the literature, but a comprehensive review on this topic is lacking. This review aims to address this gap by examining the influence of CeO2 NPs on the release rate of reactive oxygen species (ROS) in various organs of mice. CeO2 NPs have demonstrated potential therapeutic applications due to their ROS-scavenging abilities, which are relevant to oxidative stress-related diseases. Recent studies investigating the effect of CeO2 NPs on ROS release rate in organs such as the liver, spleen, lung, and brain are highlighted in this article. The findings reveal a complex interaction between CeO2 NPs and the ROS system, influenced by factors such as particle dose, size, and surface chemistry. Furthermore, the impact of CeO2 NPs on ROS release rate is organ-specific and dependent on the tissue microenvironment. The review also addresses the potential toxicity of CeO2 NPs and emphasizes the need for further research to better comprehend their mechanisms of action and long-term effects. By providing valuable insights into the influence of CeO2 NPs on ROS release rate in mice organs, this review holds significant implications for the therapeutic applications of CeO2 NPs in oxidative stress-related diseases. This review contributes to the existing body of knowledge by examining the impact of CeO2 NPs on ROS release rate in various mouse organs

Recent developments in nanotechnology and nanoscience have improved methods for treating, preventing, and diagnosing a wide range of illnesses in many parts of living beings. Silver nanoparticles (Ag NPs) are among the most significant and intriguing metallic nanoparticles employed in several biological applications. To create Ag NPs, biomolecules from diverse microbial species and plant components have been researched as possible agents. Due to their physical orientation characteristics, and small size, these Ag NPs are widely employed and are said to have an impact on the performance of any other material that comes into touch with them. In addition, straightforward biological, physical, and chemical methods may be used to create Ag NPs. Due to their enhanced responsiveness to environmentally friendly technology for quantifiable synthesis, several developed nations have seen significant growth in the biosynthesis of Ag NPs. The biological method, however, is the approach to preparation that is most in demand since it is quicker, safer, less expensive, and more environmentally friendly than other techniques. In addition, the importance of Ag NPs is extensively examined in light of their numerous bioapplications, including those for antifungal, anti-inflammatory, antibacterial, Antiviral activity, Catalytic Activity, and anticancer medicines

Phytoremediation is a green emerging technology used to remove and degrade pollutants from soil and water. In this study, plants of B. vulgaris were grown in the soils, which are artificially contaminated by lead below the WHO level (12 mg/kg) and above the WHO level (72 mg/kg). After 3 months, accumulations of the lead metal were analysed in roots, leaves, and stem with the help of Atomic Absorption Spectroscopy (Perkin Elmer analyst 400). Significant decrease in level of Pb has been noted in both the treatments. Decrease in Pb level was 3.6% and 18.7% of control (0.09 and 0.43 mg/kg). It was concluded that the plant B. vulgaris is a very good phytoremediation tool to remove Pb metal from the soil

Marrubium vulgare is a tall, robust herbaceous perennial plant originating from Asia and Mediterranean and currently distributed throughout North, South America, Europe, Mediterranean and west Asia. M.vulgare thrives in any type of the soil but it prefers light calcareous, dry soils where it is sunny and warm at an altitude between 1500 –2400 m. This plant is becoming increasingly important because it is currently cultivated in different countries to be used as a source of medicine and food flavors. Also,it has more than 54 different phytocompounds such as polyphenols, monoterpenes, diterpenes and essential oils. Marrubin was the first isolated diterpenes and it’s characterized as the chemotaxonomic marker for the genus Marrubium. According to different studies, these compounds are responsible for antioxidant, antimicrobial, antifungal, analgesic, and anti-inflammatory, wound healing and anthelmintic activities. Due to these biological activities, hydroalcoholic extracts of Marrubim vulgare have been exploited for their therapeutic nature by traditional healers to cure several illnesses in Algeria. This review is to assess the different studies of hydroalcoholic extracts of Marrubium vulgare for different biological activities.

The objective of this work was to study the influence of livestock farming type on the performance of broilers chickens (COBB 500 strains) in the semi-arid region of Sétif in Algeria. It has been determined the zootechnical parameters of chickens (live weight (g), Average daily gain, Consumption Index, Mortality) for control of livestock farming type. Indeed, the growth of broiler chickens was influenced by livestock farming type; the live weight and the average daily gain respectively were linked to livestock farming type (p < 0.05). Whereas the consumption Index was close to the meaning (p=009). Broiler chickens of larges breeders had more growth performance with heavy carcasses (2872, 22±251,39 g), the more the average daily gain (61,94±7,23 g/day), and better consumption index (1,76 ± 0,16) at 47 days of age. The mortality rate, in fact, is high and exceeds 10%. The efforts must be concentrated on equipping buildings, hygiene rules and health programs, strengthening the training of the human factor to obtain the best performance from the broiler chicken: a low mortality rate, better weight growth and an improved consumption index

Shea butter extracted from the nuts of Vitellaria paradoxa is utilized as food, medicine and a major source of income especially in the rural communities. The butter is reported to vary in their physicochemical compositions which may affect the sunscreen and stability of it, thus, the need for the present study. Shea nuts were collected from Ngaski (A), Bosso (B) and Yamaltu-Deba (C) of northern Nigeria. The in-vitro sunscreen activity was determined using UV-spectrophotometer and the stability study using plastic, clear and amber bottles stored in different conditions. The shea butter samples showed high SPF values at 1.00 % with shea butter C having the highest value at 37.49 % while shea butter A had the least value at 25.17. All the butter had sunscreen values less than 1 % at 0.50%. Samples stored in plastic, colourless and amber bottles in the refrigerator had higher moisture content while those stored at room temperature had lower moisture content, although samples in amber bottles stored in refrigerator were found to less peroxide values.

The article tries to shed light on the antibacterial power of rosemary oils to see if there is a possibility of making drugs but also to compare this power with that existing in commercial oils of rosemary and to check if these formulas really contain oils rosemary. This study consisted of the extraction of the essential oil from the studied plant followed by preliminary phytochemical tests and then by TLC analyzes to determine exactly the different compounds that characterize the species and then by the antibacterial study on the plants diluted essential oils (synthesized and commercial). Phytochemical tests have shown that essential oils contain many chemicals and active ingredients that give rosemary a wide range of indications : The TLC of the raw extract shows stains, indicating the presence of flavone, hydroxyflavone, Dihydroxyflavone, flavanones, methoxyflavones and flavonols ; they are compounds of paramount importance in the therapeutic effects enjoyed by rosemary. The bacteriological study on essential oils (extract and commercial) by the process represented on the concentrated disk of essential oils shows good antibacterial activity on the fixed stem. Essential oils extracted from rosemary from Algeria will be of some economic interest in the Algerian pharmaceutical industry. The negative test for commercial rosemary essential oil compared to the positive tests of our extract can tell us more about the counterfeit that characterizes this area. The study confirms the interest we must bring to this plant, not only for its characteristics in the perfume industry, but especially for its undisputed medical virtues.
