background and objectives: different trichoderma species play role as suitable alternative for chemical fertilizers and successful biological tool in stable agriculture. these microorganisms show rivalry in food and place sources. they establish in the rhizosphere of most agricultural and non-agricultural plants via producing spores. they also could induce resistance in plants. these properties...

Abstract. Yusran Y. 2023. Isolation and screening of Pseudomonas fluorescens isolates against Fusarium oxysporum f.sp. radicis-lycopersici their effects on seedling growth Paraserianthes falcataria. Biodiversitas 24: 2294-2301. plays a major role in biological control pathogens plant promotion as well with various mechanisms. The aim the present study was to determine biochemical characteristic...

The potential of different bacterial-feeding Rhabditida to consume isolates of Burkholderia cepacia with known agricultural biocontrol ability was examined. Caenorhabditis elegans, Diploscapter sp., Oscheius myriophila, Pelodera strongyloides, Pristionchus pacificus, Zeldia punctata, Panagrellus redivivus, and Distolabrellus veechi were tested for growth on and preference for Escherichia coli O...

Solanum lycocarpum St. Hil. is an endemic plant of the Brazilian tropical savannah (cerrado) that capable growing on acidic and nutrient-poor land, ability which attracts attention to its rhizospheric microbiota, including growth-promoting rhizobacteria (PGPR). In this work, 131 bacterial strains were isolated from rhizosphere samples S. tested in vitro for direct mechanisms growth promotion (b...

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...

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...

is the major bacterial disease in tomato, Background: Ralstonia solanacearum which invades the roots of diverse plant hosts and colonizes xylem vessels causing wilt, especially in tropical, subtropical and warm-temperate regions. R. produces several toxins helping it to invade the plant’s natural solanacearum defense mechanism. Native isolates of Trichoderma spp., Pseudomonas and can be used as...

The purpose of this study was to evaluate and assess the plant growth promoting characteristics and diversity of major tef rhizosphere isolates from central Ethiopia. A total of 162 bacteria were isolated from rhizosphere of tef [Eragrostis tef (Zucc.) Trotter] and characterized. While screening using some plant growth promoting characteristics, only about sixty six of the isolates were found t...

Contamination of agriculture land by heavy metals is a worldwide risk that has sped up noticeably since the beginning of the industrial revolution. Hence, there arise the demands of heavy metal tolerant plant growth promoting bacterial strains for specific metal contaminated agricultural sites restoration. In this study, 36 bacterial isolates were screened out from the rhizospheric soil of Phas...
