The bacterial endophytic communities of four plants growing abundantly in soils highly contaminated by hydrocarbons were analyzed through culturable and culture-independent means. Given their tolerance to the high levels of petroleum contamination at our study site, we sought evidence that Achillea millefolium, Solidago canadensis, Trifolium aureum, and Dactylis glomerata support high levels of...

Foot rot disease (Phytophthora capsici) causes severe economic losses to cultivators of black pepper. Fungicides used for managing the adversely affect export potential product due their residual toxicity. Endospore-forming bacterial strains, Bacillus amyloliquefaciens VLY24, pumilus VLY17, and velezensis PCSE10 were evaluated growth promotion suppression in pepper nursery at two locations Kera...

Twenty isolates of bacteria were successfully isolated from rhizosphere soil samples collected from different plant species growing at various locations in North Jeddah, Saudi Arabia to investigate their effects on Cucumis sativus L. cv. Marketmore growth and damping-off disease caused by Pythium aphanidermatum. The results of dual culture method showed that only three isolates out of twenty, w...

The present study screened bacteria isolated from rice rhizosphere for various beneficial traits related to three categories of plant growth promotion, abiotic stress tolerance, and compatibility with multiple agrichemicals identify a microbial consortium that performs better than individual isolates in improving under normal stressful environmental conditions. Among thirty-two screened, 29, 9,...

Ethanol producing bacteria are useful in industrial production of biofuel. There are interesting for screening of active bacteria from natural resources and introduce to biofuel industries. The present study aims to isolation of ethanol producing bacteria with characterization, optimization, and evaluation of their ethanol productivity. Samples from various fruits, plant saps and soils were scr...

The compatibility of strains is crucial for formulating bioinoculants that promote plant growth. We herein assessed the compatibility of four potential bioinoculants isolated from potato roots and tubers (Sphingomonas sp. T168, Streptomyces sp. R170, Streptomyces sp. R181, and Methylibium sp. R182) that were co-inoculated in order to improve plant growth. We screened these strains using biochem...

This study aimed to investigate the presence of beneficial microorganisms in micropropagation Pyrus communis rootstocks through isolation, identification, and selection auxin-producing bacteria. The selected were also inoculated vitro evaluate their effect on plant rooting process behavior during acclimatization phase. results showed endophytic tissue cultures ‘OH×F87′ ‘PDW’ selections. A low d...

Because of inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. Myrtus communis is amedicinal plant which had many uses in traditional medicine. In this study, ethanol leave extractof this plant is tested on Acinetobacter baumannii. In the case of antimicrobial evaluation ofplants, one o...
