Abstract:
Abstract Jet fuel is frequently contaminated with microorganisms that can cause corrosion of fuel tanks. The purpose of this work was to survey the microorganisms currently found in sump water and biofilms of aluminum alloy 2024 (AA2024) fuel tanks containing JP-8 jet fuel. Aerobic and anaerobic bacteria were found in low numbers in sump water, while fungi were rarely present. Numbers of aerobic bacteria and fungi were much higher in biofilms from the tank surface. Common aerobic bacteria were identified belonging to the genera Bacillus and Kurthia. Two fungal isolates were identified as Penic

The efficiency of zinc oxide nanoparticles (ZnO-NPs) in inhibiting Phytophthora spp. growth in both durian fruits and stems is demonstrated. The size of ZnO-NPs used was in range of 25-50 nm in diameter. Diseased durian sample were collected from a durian orchard located in southern of Thailand. The pathogen of diseased durian was isolated for subsequent morphological identification. Three distinct strains of Phytophthora spp. (designated as PHY41, PHY45, PHY49) were successfully isolated and were found in colonies with rings and stellate pattern, ovoid, limoniform sporangium with semi-papilla

Antimicrobial resistance is a global threat to humans, prompting an increasing interest in exploring and developing novel antimicrobial substances derived from diverse sources. Together with the emergence of new diseases the search for novel drug leads has intensified. Less explored microbial habitats have become prime targets in mining for novel antimicrobial molecules. Secondary metabolites synthesized by lichen-associated fungi are good potential targets in this regard.

The intent of this proposal was to study the interaction between nonpathogenic mutants of Colletotrichum magna and Fusarium oxysporum, and the cucurbit host defense system. We had shown previously that a nonpathogenic endophytic mutant path- 1 of C. magna, caused no visible disease symptoms but protected watermelon seedlings from disease caused by the wildtype isolate and F. o. niveum. Objectives were: 1) Determine the microscopic, biochemical and molecular genetic interaction between "protected" (path- 1 colonized) cucurbit hosts and wildtype isolates of C. magna; 2) Isolate non-pathogenic mu

Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds.

Spore germination is a common and fundamental event in fungal development and in many instances an essential phase of fungal infection and dissemination. Spore germination is also critical for hyperparasites to function as biocontrol agents as well as in fermentation proceses. Our common objective is to understand the mechanisms which regulated spore germination and identify factors involved in pathogenicity related prepenetration development.
