Abstract Background Actinobacteria is as a group of advanced filamentous bacteria. Rare are special interest they rarely isolated from the environments. They major source important bioactive compounds. Determining proper strategy for identification harboring biosynthetic gene clusters and producing molecules challenging platform. Methodology In this review, we discuss consequence microbiological molecular methods rare Actinobacteria. addition to that, shed light on ’s significance in...
Abstract Using plant extracts in the green synthesis of nanoparticles has become an environmentally acceptable approach. In our study, copper oxide (CuO NPs) were synthesized using ethanolic Azadirachta indica and Simmondsia chinensis . CuO NP formation was confirmed by change color UV‒visible spectroscopy NPs peaked at a wavelength 344 nm). TEM images semispherical shape NPs, with particle sizes ranging from 30.9 to 10.7 nm. The antibacterial activity these evaluated agar diffusion method...
Abstract Background Antibiotic resistance is on the rise, and new antibiotic research has slowed in recent years, necessitating discovery of possibly novel microbial resources capable producing bioactive compounds. Microbial infections are gaining to existing antibiotics, emphasizing need for medicinal molecules be discovered as soon possible. Because possibilities isolating undiscovered actinomycetes strains have decreased, quest products shifted rare genera from regular environments or...
Abstract In the battle against clinical infections particularly resistant pathogens, creation of new antimicrobial drugs is essential. This study focuses on synthesis and characterization Lipase-CuO nanoparticle conjugates in order to investigate their antibacterial efficiency. Lipase enzyme CuO nanoparticles were synthesized biologically by specific selected fungal strains. Statistical optimization lipase was done using a Plackett-Burman design giving two enhancement models for production...
Antibiotic resistance occurs rapidly and naturally. However, the misuse of antibiotics is accelerating process. And therefore, exploring new has been a great demand in order to save people's life. Actinobacteria have major source antibiotics. In this study, we focused on rare types actinobacteria which are hard isolate from environment by traditional methods. Fifty were isolated Egyptian soils, they screened against some bacterial pathogens (Staphylococcus aureus ATCC 6538, Pseudomonas...
Objective: to review the practice of maxillofacial trauma surgery in Makka city, Saudi Arabia, as road traffic accidents is considered a major cause morbidity and mortality kingdom. Materials methods: chart all cases that visited hospital Alnoor specialist (NSH), from October 2005 2013 was collected. A total 1132 patients’ records were retrieved. Amongst, 965 injuries included study completed information found. Charts incomplete records, soft tissue only, or solitary dental injury excluded....
The population structure of Pseudomonas aeruginosa is panmictic-epidemic in nature, with the prevalence some high-risk clones. These clones are often linked to virulence, antibiotic resistance, and more morbidity. clonal success these lineages has been acquisition spread mobile genetic elements. main aim study was explore other molecular markers that explain their global success. A comprehensive set 528 completely sequenced P. genomes analyzed. examined using Multilocus Sequence Typing...
A novel Streptomyces sp. Ru87 was isolated from Egyptian soil and showed significant inhibition activities against a number of food blood borne pathogens. Morphological chemotaxonomic characteristics that belongs to genus Streptomyces. 16 S rRNA gene sequence (KY775360), 98% identity with cacaoi strain NBRC 12748. However, phylogenetic analysis indicated it is distinct the known species. cultured extract this inhibits growth Staphylococcus aureus some other foodborne The highest yield...
A distinct strain named Micromonospora sp.Rc5 was isolated from Sinai desert of Egypt and recorded high antagonistic activities against some food bloodborne pathogens.Morphological chemotaxonomy characterization confirmed that this isolate belongs to genus Micromonospora.Sequencing partial 16S rDNA BLASTN showed Rc5 is identical haikouensis (99%) but with low bootstrap value in NJ phylogenetic tree.Comprehensive optimization several growth factors performed including initial pH, incubation...
Egyptian deserts are an underexplored ecological niche, especially the Sinai Peninsula. In our recent study, we explored this extreme environment and shed light on bioactive capabilities of desert Actinobacteria isolated from Sinai. Fifty were using mineral salt media, basal starch casein media. The filtrate Streptomyces sp. DH 7 displayed a high inhibitory effect against multidrug-resistant Staphylococcus aureus (MRSA) strains. 16S rDNA sequencing confirmed that isolate DH7 belongs to genus...
Abstract Background Foodborne illness is a public health alarm with deleterious effect on human and the economy all over world. Searching for possible solutions to beat foodborne pathogens still demanding concern. The scope of this study evaluate antimicrobial activity some natural organic compounds against important including Escherichia coli O157:H7 C9490, Listeria monocytogenes Lm2 Scott A 4b, Salmonella enteritidis 8-9-99. Results bactericidal eight their concentrations were evaluated by...
Pathogens resistant to antimicrobials form a significant threat public health worldwide. Tackling multidrug-resistant pathogens via screening metagenomic libraries has become common approach for the discovery of new antibiotics from uncultured microorganisms. This study focuses on capturing nonribosomal peptide synthase (NRPS) gene clusters implicated in synthesis many natural compounds industrial relevance. A NRPS PCR assay was used screen 2976 Escherichia coli clones soil library target...
Vital pulp therapy has always been a topic of debate in pediatric dentistry. Formocresol (FC) the most commonly used pulpotomy agent primary teeth. Despite its high rate clinical success, concerns about safety have raised literature. However there is lack evidence that establishes superiority one type treatment allowing for replacement FC. To evaluate short term clinical, radiographic and histological success TheraCal LC, vital molars, sixty mandibular molars indicated were randomly...
Pseudomonas fluorescens is considered among the main spoilage microorganisms due to its ability produce proteases. Food deterioration caused by has a major impact on food quality and environment. The inactivation of growth protease production was intensively investigated with use Salmide®, A Sodium Chlorite-Based Oxy-halogen Disinfectant. unique M9 media also developed assure sufficient productions different mutants as microbioreactor. Mutations were induced classical whole-cell mutagenesis...

Abstract A novel portable chamber was developed to extend the shelf life of chicken breasts through a synergistic treatment gamma irradiation and Salmide®, sodium chlorite-based oxy-halogen. This combination successfully enhanced by utilizing low dosage alongside concentrations Salmide (200 ppm chlorite). Fresh breast samples were treated with irradiation, then packed in ice containing within chamber, subsequently stored for 20 days refrigerator at 4 °C ± 1. The study investigated aerobic...
