Crop plants are continuously exposed to various abiotic stresses like drought, salinity, ultraviolet radiation, low and high temperatures, flooding, metal toxicities, nutrient deficiencies which act as limiting factors that hampers plant growth agricultural productivity. Climate change intensive practices has further aggravated the impact of leading a substantial crop loss worldwide. have get a...

Background: The rhizosphere contains many beneficial microorganisms which have a positive action on plant growth and development. In both natural controlled ecosystems, plant-associated bacteria play key role in supporting increasing health growth. Methods: this study, promoting Bacillus isolates associated with the of black pepper (Piper nigrum) were selected used for bioassay experiments host...

Pathogenic microorganisms overcome the host’s innate and adaptive immune system and cause local or systemic infections, potentially leading to organ failure, sepsis, or even death. Some microorganisms can also directly or indirectly alter the differentiation and proliferation of host cells, promoting the development of tumors. A large number of oncogenic viruses have been identified and estimat...

The potential for commensal microorganisms indigenous to a host (the 'microbiome' or 'microbiota') to alter infection outcome by influencing host-pathogen interplay is largely unknown. We used a multi-omics "systems" approach, incorporating proteomics, metabolomics, glycomics, and metagenomics, to explore the molecular interplay between the murine host, the pathogen Salmonella enterica serovar ...

The importance of Streptococcus mutans in the etiology and pathogenesis of dental caries is certainly controversial, in part because excessive attention is paid to the numbers of S. mutans and acid production while the matrix within dental plaque has been neglected. S. mutans does not always dominate within plaque; many organisms are equally acidogenic and aciduric. It is also recognized that g...

Nitrilase enzymes (nitrilases) catalyse the hydrolysis of nitrile compounds to the corresponding carboxylic acid and ammonia, and have a wide range of industrial and biotechnological applications, including the synthesis of industrially important carboxylic acids and bioremediation of cyanide and toxic nitriles. Nitrilases are produced by a wide range of organisms, including plants, bacteria an...

Periodontitis is a chronic oral inflammatory disease caused by microorganisms. Human β‑defensin‑3 (HBD‑3) is an endogenous antimicrobial peptide that inhibits a broad spectrum of microorganisms. Cell sheet technology has been widely applied in tissue and organ reconstructions. In the current study, it was aimed to investigate the anti‑inflammatory effect of periodontal tissue engineered by HBD‑...

Soil microorganisms, in particular so-called plant growth promoting rhizobacteria (PGPR), can positively affect plants, stimulating by changing their metabolism. In addition, these bacteria synthesize hormone-like chemicals that influence the formation of primary roots. This work was aimed to determine possibility using sterile cell-free cultural medium obtained after endophytic Priestia endoph...

The need for an agricultural system in the Mediterranean countries consuming fewer chemicals and respecting environment becomes a pressing element. use of natural beneficial microorganisms that enhance soil fertility could be promising solution. Lebanese Beneficial Microorganisms (LBM) were extracted evaluated their capacity promoting plant growth. Two combinations LBM compared to chemical fert...

Atmospheric nitrogen deposition affects the health of forest ecosystems by altering soil microbial activity. However, effects addition levels, morphology and ecosystem type on whether is beneficial or detrimental to controver-sial, most studies have focused negative structure. Based this, this study conducted a four-year experiment (NaNO3) at two levels (10 20 kg N hm−2·yr−1) in understory Lari...
