Abstract:
Exploration of Yeasts and Bacteria as Antagonist Agent of Rice Blast PathogenBlast disease (Pyricularia oryzae) is a major disease of rice that causes 61% yield losses. An alternative way to control the disease is applying antagonistic agents, both yeasts and bacteria. This study was aimed to obtain yeast and bacterial isolates that can be used as antagonistic agents to effectively control blast disease. Yeasts and bacteria were isolated from the leaves of Digitaria sp., Panicum sp., and Pennisetum sp.. The isolates of yeasts and bacteria were screened following hypersensitive test on tobacco

Probiotics are defined as live microorganisms that provide beneficial effects when consumed in sufficient quantities. Currently available probiotics are bacteria such as Lactobacillus, Bifidobacterium and Bacillus. In recent years, yeast has presented great potential for the development of new probiotics.

This raises the question of whether other yeast species have probiotic properties. Recent investigations show that some species with probiotic evidence are Kluyveromy

Two bacteria of the genus Bacillus were used, one was cultured from soil, while the other was cultured from parkia. These were subcultured using an algae medium to produce 13500 ml of washed bacteria cells, which were immobilized in 1,500 ml of silica gel. A nutrient solution was also prepared by mixing 171 g of yeast extract, 1710 g of urea, and 1710 g of calcium lactate in water. Water, polyvinyl alcohol (PVA), bacteria cells, and silica gel contribute

This paper describes the application of the Segment Anything Model (SAM) to the analysis and image processing of microbiological samples containing common types of bacteria and yeast that can be found in various environments. The SAM model was tested on images from the AGAR dataset, which contains 18,000 images of microbiological samples containing five microorganisms such as Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans.

Известно, что ризосферные микроорганизмы оказывают положительное влияние на растение-симбионт: они обеспечивают доступ питательных веществ растениям, защищают их от фитопатогенов, а также продуцируют физиологически активные и ростостимулирующие веществ [1,4]. Важно отметить, что положительный эффект ризобактерий на растение достигается только при успешной колонизации ими его ризосферы, начальным этапом которой является адгезия [2]. Явление адгезии интенсивно исследуется в последние годы. It is known that rhizospheric microorganisms have a positive effect on the symbiont plant: they provide nut

Abstract:
The aim of the studies was to create a dry preparative form of a biopreparation based on Bacillus subtilis spores and the determination of an acceptable shelf life without significant loss of the spores viability. The technology for obtaining a dry formulation includes the following steps: cultivation of the bacteria B. subtilis in a liquid nutrient medium to the stage for the maximum sporulation; separation of spore biomass from the nutrient medium; adsorption of spores on a mixture of starch and powdered sugar and , if necessary, the subsequent addition of powdered sugar till creation a pulv

n this study, the antimicrobial activity of five hybrids of 3-acetyl- 4-hydroxy coumarin with neurotransmitters was determined: dopamine (1), tyramine (2), octopamine (3), norepinephrine (4) and methoxy-tyramine (5). Antimicrobial activity was assessed using the microdilution method incorporating resazurin, with determination of MIC/MMC concentrations. Testing involved twelve microorganisms, five of which were sourced from mine wastewater. The best activities were shown by substances (1) and (4) on Bacillus pumilus and Pantoea agglomerans, where the MIC was 31.8 μg/mL. Pantoea agglomerans show

In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this purpose. These bacteria have endured the harsh weather of high temperatures, humidity, and alkaline soil conditions. Hence, are a potential candidate for long-term self-healing in concrete structures that are subjected to the climate of the Middle Eastern region. The bacteria were encapsulated in sodium alginate beads then the beads were added to the cement-sand mortar. The

Abstract:
Concrete is the foremost building material broadly used in building construction, but cracks in concrete are inevitable and are one of the inherent weakness of concrete. The major downside of concrete is its low tensile strength due to which micro crack occurs when the load applied is more than its limit and this paves way for the seepage of water and other salts. This initiates corrosion and makes the whole structure vulnerable and leads to the failure of structure. To remediate this type of failure due to cracks and fissures, an approach of using bio mineralization in concrete has evolved in

Objectives: The overall objective as defined in the approved proposal was the development of a whole-cell sensor panel for the detection of endocrine disruption activities of agriculturally relevant chemicals. To achieve this goal several specific objectives were outlined: (a) The development of new genetically engineered wholecell sensor strains; (b) the combination of multiple strains into a single sensor panel to effect multiple response modes; (c) development of a computerized algorithm to analyze the panel responses; (d) laboratory testing and calibration; (e) field testing.
