Zygote gene expression and plasmodial development in Didymium iridis A Thesis presented in Partial fulfillment of the Requirements for the Degree of Master of Biology By Sean Schaefer 2019 Advisor: Dr. Margaret Silliker Department of Biological Sciences College of Liberal Arts and Sciences DePaul University Chicago, IL Abstract: Didymium iridis is a cosmopolitan species of plasmodial slime mold consisting of two distinct life stages. Haploid amoebae and diploid plasmodia feed on microscopic organisms such as bacteria and fungi through phagocytosis. Sexually compatible haploid amoebae act as gametes which when fused embark on an irreversible developmental change resulting in a diploid zygote. The zygote can undergo closed mitosis resulting in a multinucleated plasmodium. Little is known about changes in gene expression during this developmental transition. Our principal goal in this study was to provide a comprehensive list of genes likely to be involved in plasmodial development. -

The influence of specific sub-sets of phenolic compounds on the growth and metabolism of lactic acid bacteria (LAB) and on the diversity of Oenococcus oeni in inoculated and non-inoculated red wines was investigated during malolactic fermentation (MLF) and subsequent storage. Representative O. oeni strains from wines treated with flavonols and trans-resveratrol were isolated and analyzed by pulsed-field gel electrophoresis of rare restriction enzyme digests (REA-PFGE). 28 days after MLF initiation, strains from all samples had entered the death phase, except those supplemented with trans-resveratrol. In the non-inoculated samples, the onset of lactic acid production was apparently delayed by all compounds tested, except for the flavan-3-ols. Increased levels of phenolics also delayed citrate consumption in inoculated samples. -

A Taxonomic Note on the Genus Lactobacillus

Gänzle9,13,*,† and Sarah Lebeer2† Abstract The genus Lactobacillus comprises 261 species (at March 2020) that are extremely diverse at phenotypic, ecological and gen- otypic levels. This study evaluated the taxonomy of Lactobacillaceae and Leuconostocaceae on the basis of whole genome sequences. Parameters that were evaluated included core genome phylogeny, (conserved) pairwise average amino acid identity, clade- specific signature genes, physiological criteria and the ecology of the organisms. Based on this polyphasic approach, we propose reclassification of the genus Lactobacillus into 25 genera including the emended genus Lactobacillus, which includes host- adapted organisms that have been referred to as the Lactobacillus delbrueckii group, Paralactobacillus and 23 novel genera for which the names Holzapfelia, Amylolactobacillus, Bombilactobacillus, Companilactobacillus, Lapidilactobacillus, Agrilactobacil- lus, Schleiferilactobacillus, Loigolactobacilus, Lacticaseibacillus, Latilactobacillus, Dellaglioa, -

Lists of Names of Prokaryotic Candidatus Taxa
NOTIFICATION LIST: CANDIDATUS LIST NO. 1 Oren et al., Int. J. Syst. Evol. Microbiol. DOI 10.1099/ijsem.0.003789 Lists of names of prokaryotic Candidatus taxa Aharon Oren1,*, George M. Garrity2,3, Charles T. Parker3, Maria Chuvochina4 and Martha E. Trujillo5 Abstract We here present annotated lists of names of Candidatus taxa of prokaryotes with ranks between subspecies and class, pro- posed between the mid- 1990s, when the provisional status of Candidatus taxa was first established, and the end of 2018. Where necessary, corrected names are proposed that comply with the current provisions of the International Code of Nomenclature of Prokaryotes and its Orthography appendix. These lists, as well as updated lists of newly published names of Candidatus taxa with additions and corrections to the current lists to be published periodically in the International Journal of Systematic and Evo- lutionary Microbiology, may serve as the basis for the valid publication of the Candidatus names if and when the current propos- als to expand the type material for naming of prokaryotes to also include gene sequences of yet-uncultivated taxa is accepted by the International Committee on Systematics of Prokaryotes. Introduction of the category called Candidatus was first pro- morphology, basis of assignment as Candidatus, habitat, posed by Murray and Schleifer in 1994 [1]. The provisional metabolism and more. However, no such lists have yet been status Candidatus was intended for putative taxa of any rank published in the journal. that could not be described in sufficient details to warrant Currently, the nomenclature of Candidatus taxa is not covered establishment of a novel taxon, usually because of the absence by the rules of the Prokaryotic Code. -

Endo Department of Microbiology, Stellenbosch University, Private Bag X1, 7602 Matieland (Stellenbosch), South Africa Submitted for publication: March 2009 Accepted for publication: May 2009 Key words: Taxonomy; malolactic bacteria; key characteristics Oenococcus oeni is the best malolactic bacterium adapted to low pH and the high SO2 and ethanol concentrations in wine. Leuconostoc mesenteroides and Leuconostoc paramesenteroides (now classified asWeissella paramesenteroides) have also been isolated from wine. Pediococcus damnosus is not often found in wine and is considered a contaminant of high pH wines. Pediococcus inopinatus, Pediococcus parvulus and Pediococcus pentosaceus have occasionally been isolated from wines. Lactobacillus brevis, Lactobacillus plantarum, Lactobacillus buchneri, Lactobacillus hilgardii (previously Lactobacillus vermiforme), Lactobacillus fructivorans (previously Lactobacillus trichoides and Lactobacillus heterohiochii) and Lactobacillus fermentum have been isolated from most wines. Lactobacillus hilgardii and L. fructivorans are resistant to high acid and alcohol and have been isolated from spoiled fortified wines. Lactobacillus vini, Lactobacillus lindneri, Lactobacillus nagelii and Lactobacillus kunkeei have been described more recently. The latter two species are
