Evolutionary and Genomic MicrobiologyStrain-Specific Metabolic Requirements Revealed by a Defined Minimal Medium for Systems Analyses of Staphylococcus aureusAs researchers try to understand and combat the development of antibiotic resistance in pathogens, there is a growing need to thoroughly understand the physiology and metabolism of the microbes. Staphylococcus aureus is a threatening pathogen with increased antibiotic resistance and well-studied virulence mechanisms. However, the adaptive mechanisms used by this...
Invertebrate Microbiology | SpotlightYeast Volatomes Differentially Affect Larval Feeding in an Insect HerbivoreYeasts interface insect herbivores with their food plants. Communication depends on volatile metabolites, and decoding this chemical dialogue is key to understanding the ecology of insect-yeast interactions. This study explores the volatomes of eight yeast species which have been isolated from foliage, from flowers or fruit, and from plant-feeding insects. These yeasts each release a rich bouquet of volatile metabolites, including a...
BiodegradationBioremediation of Dichlorodiphenyltrichloroethane (DDT)-Contaminated Agricultural Soils: Potential of Two Autochthonous Saprotrophic Fungal StrainsThe spread and environmental accumulation of DDT over the years represent not only a threat to human health and ecological security but also a major challenge because of the complex chemical processes and technologies required for remediation. Saprotrophic fungi, isolated from contaminated sites, hold promise for their bioremediation potential toward toxic organic compounds, since they might provide an environment-friendly solution to...
PhysiologyDistinct Roles of Shewanella oneidensis Thioredoxin in Regulation of Cellular Responses to Hydrogen and Organic PeroxidesThe Trx and Grx systems are deeply involved in bacterial responses to H2O2-induced oxidative stress. However, little is known about their roles in response to other ROS, such as organic peroxides (OPs). In this study, we used S. oneidensis as a research model to investigate the interplay between Trx/Grx and OxyR/OhrR. We show that Trxs mediate...
PhysiologyGrowth Dynamics and Survival of Liberibacter crescens BT-1, an Important Model Organism for the Citrus Huanglongbing Pathogen “Candidatus Liberibacter asiaticus”Liberibacter crescens is a bacterium that is closely related to plant pathogens that have caused billions of dollars in crop losses in recent years. Particularly devastating are citrus losses due to citrus greening disease, also known as Huanglongbing, which is caused by “Candidatus Liberibacter asiaticus” and carried by the Asian citrus psyllid. L....
