Biofilm formation by the fish pathogen Flavobacterium columnare: a quantitative and qualitative study
(2013-04-30)
The objective of this study was to evaluate the effect that temperature, pH, salinity, hardness and carbohydrates have on biofilm formation by the fish pathogen Flavobacterium columnare. Nineteen F. columnare strains, ...
Biofilm formation, virulence attenuation and comparative genomics of the fish pathogen Flavobacterium columnare
(2018-11-27)
Flavobacterium columnare is an important bacterial fish pathogen that causes great economic losses in aquaculture. In this dissertation I aimed at characterizing part of its life cycle including the transition between ...
Biofuel Production from Hydrothermal Liquefaction of Algae and Its Subsequent Upgrading
(2017-11-30)
Algae are considered as a promising feedstock for biofuel production. The conversion of algae to biofuel was investigated in this study. The study was concentrated in two main areas: hydrothermal liquefaction of algae into ...
Biogeochemical Effects of Silvicultural Management on Intermittent Streamside Management Zones in the Coastal Plain of Alabama
(2008-05-15)
Three experimental intermittent watersheds in the Coastal Plain of Alabama were subjected to varying Streamside Management Zone (SMZ) silvicultural treatments in 2000: reference, partial cut, and clearcut. Biomass and ...
Biogeochemical Influence of Chinese Privet in Riparian Forests in West Georgia and the Influence of Oyster Harvesting in Apalachicola Bay, Florida
(2009-05-04)
In the Southeastern U.S., urbanization influences nutrient availability, species composition, and water quality among other ecosystem processes. This study examined the influence of invasive species spread, facilitated ...
BIOGEOCHEMICAL STORAGE AND TRANSFORMATION OF SEDIMENTS FROM GEOGRAPHICALLY ISOLATED WETLANDS IN AGRICULTURE LANDSCAPES
(2022-12-08)
Geographically Isolated Wetlands (GIWs) provide many beneficial ecosystem services including biogeochemical storage and processing. However, due to the absence of hydrologic connectivity to surface waters, they lack legal ...
Biogeographical and Genomic Analysis of Eleusine Species
(2021-12-06)
Abstract
Eleusine Gaertn. (Poaceae, subfamily Chloridoideae), is a small taxon of closely related and distinct diploids and tetraploids endemic to Africa that have been scrutinized from vegetative, floral, cytological, ...
Biohybrid and Biomimetic Platforms for Programmable Therapeutic Delivery
(2008-08-15)
Drug and gene delivery carriers such as hydrogels and metallic nanoparticles have shown remarkable promise as programmable platforms in the targeted delivery of their payload. In this work, the fundamental principles of ...
Bioinspired Microphysiological Systems for in vitro Elucidation of Prostate Tumorigenic Progression and Application in Pre-clinical Therapeutic Evaluation
(2022-12-05)
Contrary to conventional belief, prostate cancer tumors are not merely uniform clusters of cancerous cells that undergo uncontrollable growth and migrate indiscriminately throughout the body. Instead, the prostatic tumor ...
Biological characterization of Tritrichomonas foetus of bovine and feline origin
(2008-05-15)
Tritrichomonas foetus is a causative agent of venereal trichomoniasis in cattle characterized by early fetal death and post-coital pyometra. Reports have suggested that T. foetus (or a similar organism) is also the causative ...
Biological Control Potential of Spore-forming Plant Growth-Promoting Rhizobacteria Suppressing Meloidogyne incognita on Cotton and Heterodera glycines on Soybean
