Fungi are attractive as reducing and stabilizing agents in the biogenic synthesis of silver nanoparticles due to production considerable amounts proteins, high yields, simplicity handling, low toxicity residues. Nanotechnology is one prospective technologies that could be utilized address recent issues agrichemical lines, nanotechnology lines can also have drawbacks. As a result, brand-new branch called "green nanotechnology" was developed, integrating biological ideas with physical chemical...

In this study, investigations were carried out to assess the efficiency of two plant essential oils; rosemary and oregano as natural food preservatives. The effect oils at concentrations 0.1%, 0.5% 1% was studied in soft cheese against Salmonella enteritidis Escherichia coli fridge temprature over a 14-day period. performed well inhibition S. E. . It is concluded that selected can act potent inhibitors both microorganisms product. At same time, evaluation their safety preservatives...

The biological synthesis of silver nanoparticles offers a promising alternative to traditional physical and chemical methods due its inherent simplicity, non-toxic nature, environmental friendliness. Within this study, endophytic fungi hosted six wild plants in Arish City, North Sinai, Egypt have been isolated by surface sterilization technique on different isolation media. Twelve species, based their frequency occurrence, out thirty recovered taxa were tested for capability synthesize...

Technological application of essential oils, as natural antimicrobial agents, to reduce the effect pathogenic microorganisms, requires new methods detection. The present work evaluated parameters activity oils rosemary (Rosmarinus officinalis) on two strains Escherichia coli and Staphylococcus aureus. MBC MIC values were 2.5, 25 μl ml -1 , 1.25 5 for respectively. In this study, an attempt has been made evaluate randomly amplified polymorphic DNA (RAPD) analysis its potential establish oil....

Solar salterns are an ideal model for extreme environments since they contain a halophilic microorganisms that must adapt to these conditions. In North Sinai, have not gotten much attention. However, the focus of our investigation was on salterns' waters and saline soil. The study this microflora showed it had lot different shapes, functions, ways using energy. molecular analysis provided us with phylogenetic relationship included Aspergillus isolates as well archaeal from genera Haloarcula,...

Exploring of extremophilicArchaeaand their enzymes had great significance to biocatalysis. Enzymes produced by Archaea allow improvement in multiple sectors industry. They can help reduce the quantity waste energy and material consumption, thus making technology more environmentally–friendly. This study aimed screen hydrolytic extremozymes different Soda LakesofWadi Al-Natrun, Egypt, enzymatic agar-plate assays molecular-based methods. Five hundred thirty-fivehaloalkaliphilicarchaeal strains...

Shotgun metagenomic DNA sequencing is an effective ecological approach that offers understanding of microbial community biodiversity and function. This study evaluated the phylogenetic diversity metabolic potential haloalkaliphilic hypersaline alkaline lake in Wadi Al-Natrun, Egypt, by using High-throughput technique. Metagenome comprised 32,149,168 reads, total read bases were 4.0G bp, with GC content 61.589% Q30 87.847%. The brine sample Ga’ar have been proceeded library construction...

Actinomycetes are the source of many secondary metabolites, enzymes, and antimicrobials that have various applications.Microorganism proliferation is aided in practice by mediated mutations utilizing UV monochromatic laser radiation.This study aimed to evaluate photostimulatory effect light on lipase, amylase antimicrobial productivity three actinomycetes' strains from genera: Micromonospora, Pseudonocardia, Nocardiopsis.The were exposed (300-400 nm) (632.8 radiations for 10 20 minutes.The...
