Growth, Yield, And Photosynthetic Dry Matter Remobilization Response Of Barley To Plant Growth Promoting Rhizobacteria (Pgpr) And Nitrogen, Abazar Abbasi, Shahram Mehri, Hossein Solimanzadeh, Saeid Alipour
Growth, Yield, And Photosynthetic Dry Matter Remobilization Response Of Barley To Plant Growth Promoting Rhizobacteria (Pgpr) And Nitrogen, Abazar Abbasi, Shahram Mehri, Hossein Solimanzadeh, Saeid Alipour
The Philippine Agricultural Scientist
A two-year factorial experiment based on a randomized complete block design with three replicates was carried out on barley cultivar LB-IRAN at the research farm of the Islamic Azad University, Ardabil, Iran, during the cropping years of 2019–2021, in order to survey the impact of plant growth-promoting rhizobacteria (PGPR) and nitrogen fertilizer on growth, yield, and remobilization of photosynthetic dry matter in barley. The first factor included five nitrogen levels: 0 (control), 25, 50, 75, 100 kg/ha net nitrogen; the second factor contained grain inoculations with four bacteria: no inoculation (control), Azotobacter chroococcum race 5, Azospirillum lipoferum race of, and …

Lung cancer is one of the most common forms of cancer diagnosed, and has the highest lethality rate across all other forms of cancer in the U.S. While current therapeutic options include chemo-, immuno-, and radio-therapy, the benefits of caloric or nutrient restriction on cancer cells has also been investigated. Due to the many biological functions associated with methionine, many have proposed a methionine restricted diet would lead to favorable outcomes when combating cancer. Although our cells are incapable of synthesizing methionine, the bacteria found in our microbiome can. Furthermore, recent discoveries suggest an independent microbiome found within tumors that …
Understanding The Kinetics Of Laser-Induced Nanowelding Of Nanoparticles And The Motility Of Bacteria When Faced With Obstacles, Ariel Rogers
Graduate Theses and Dissertations
This dissertation has two focus areas: nanoparticle nanowelding and bacteria motility in the presence of micrometer sized structures. There are two main projects for the nanoparticle nanowelding studies: “Real-time imaging of laser-induced nanowelding in solution” and “Two-color laser-induced nanostructure shape modulation.” For the real-time imaging project, I used a fluorescence microscope, a 405 nm laser, and various python packages to quantify the average size of nanowelded nanostructures as a function of time and found that the average nanostructure growth over time fit the parameters of A¯(t) ∝ c0(1−e−t/τ), where c0 represents the initial concentration of nanoparticles in the solution and …
The Role Of Cerium(Iii) In Bacterial Growth And The Microbial Transformation Of Aromatic Hydrocarbons, Shruti Sathish
The Role Of Cerium(Iii) In Bacterial Growth And The Microbial Transformation Of Aromatic Hydrocarbons, Shruti Sathish
Honors Theses
Biofilms are communities of surface-attached bacterial cells encased in an exopolymeric matrix. In this state, they are more resistant to antimicrobial treatment and can have adverse effects in medical, agricultural, and industrial settings. Whereas, as biocatalysts, biofilms from nonpathogenic bacteria enhance their performance and stability in catalysis. Unfortunately, there are several challenges when using bacteria in organic transformations due to their complex cellular chemistry. Trivalent lanthanide metals were discovered to serve regulatory roles in some bacterial catalytic processes, including those of Pseudomonas putida KT2440 (P. putida), a non-infectious Gram-negative bacterium. The main goal of our research is to use cerium(III) …
Characterization Of The Clostridioides Difficile Glycosyl Hydrolase Ccsz, Brian Lowrance
Characterization Of The Clostridioides Difficile Glycosyl Hydrolase Ccsz, Brian Lowrance
Theses and Dissertations (Comprehensive)
Bacteria inhabit many of the harshest environments on Earth; persisting and thriving in conditions thought to be unsuitable for life. One common strategy to withstand these environments is the formation of a biofilm. Biofilm composition varies greatly, depending on the underlying community that produces it. Cellulose, a polymer consistently prevalent in biofilms, has been identified as a virulence factor in many pathogens and is suspected to be involved in pathogenesis by Clostridioides difficile. C. difficile is the #1 cause of hospital acquired diarrhea, which can range from mild to life-threatening infections. Biofilm formation is hypothesized to be involved in …
