The name Charliella is proposed for a new biseriam-minid genus characterized by a four-layered wall that I thickens along the anterior side of the septa and partially occludes the chamber cavity. Charliella rossae was derived from the Globivalvulina graeca-Globivalvulina vonderschmitti lineage which also constituted the root stock of true Paraglobivalvulina (P mira) in Late Permian time. The Globivalvulina decrouezae-Septoglobival-vulina gracilis-Paraglobivalvulinoides septulifer lineage is another trend in the evolution of biseriamminids. The recognition of such a lineage in the Late Permian necessitates taxonomic revision of the biseriamminids to attribute globular and involute forms with thin and undifferentiated walls to Septoglobivalvulina, a genus which was synonymized under Paraglobivalvulina in previous work.

Sengoerina argandi, n. gen., n. sp., and its position in the evolution of Late Permian biseriamminid foraminifers Altıner, Demir (JSTOR, 1999-06-01) The name Sengoerina is proposed for a new biseriamminid genus characterized by a coiled stage of initially globular to progressively angular, biserial chambers followed by an uncoiled stage of angular, biserial chambers. Unlike Dagmarita, it has a distinct coiled stage and lacks spine-like projections at the outer margins of the chambers. Sengoerina constitutes the root stock of the angular-chambered, dagmaritin-type biseriamminids which evolved from the globivalvulines in the Late Permian.
Proteome-wide analysis of the functional roles of Bacilysin biosynthesis in Bacillus subtilis Taşkın Aras, Aslı; Özcengiz, Gülay; Department of Biology (2010) The members of the genus Bacillus produce a wide variety of secondary metabolites with antimetabolic and pharmacological activities. Most of these metabolites are small peptides that have unusual components and chemical bonds and synthesized nonribosomally by multifunctional enzyme complexes called peptide synthetases. Bacilysin, being produced and excreted by certain strains of Bacillus subtilis, is one of the simplest peptide antibiotics known. It is a dipeptide with an N-terminal L-alanine and an unusual...
Late Carboniferous and early Permian fusulinoideans in the Central Taurides, Turkey: Biostratigraphy, faunal composition and comparison Kobayashi, Fumio; Altıner, Demir (GeoScienceWorld, 2008-01-01) The Upper Carboniferous and Lower Permian rock units in the Hadim area, central Taurides, Turkey, are biostratigraphically divided into eleven fusulinoidean zones in ascending order: the Protriticites variabilis, Montiparus umhonoplicatus and Schwageriniformis schwageriniformis Zones in the Kasimovian; the Jigulites aff. formosus, Daixina asiatica and Rugosofusulina sp. A Zones in the Gzhelian; the Paraschwagerina sp. and Dutkevichia complicata Zones in the Asselian; the Paraschwagerina pseudondra and Robil...
End-Permian mass extinction of lagenide foraminifers in the Southern Alps (Northern Italy) Groves, John R.; Rettori, Roberto; Payne, Jonathan L.; Boyce, Matthew D.; Altıner, Demir (Cambridge University Press (CUP), 2007-05-01) The Permian-Triassic boundary, examined at two sections in the Southern Alps, occurs similar to 1.0 to 1.5 m above the base of the Tesero Oolite Member of the Werfen Formation in a depositionally continuous sequence of inner neritic carbonates. Lagenide foraminifers from the boundary interval comprise 27 species in 15 genera plus additional unidentified taxa, most of which became extinct during the end-Permian crisis. The only survivors were "Nodosaria" elabugae and unidentified species in Geillitzina and N...
Targeted disruption of homoserine dehydrogenase gene in Streptomyces clavuligerus and its effects on cephamycin C production Çaydaşı (Koca), Ayşe; Özcengiz, Gülay; Department of Biology (2006) The members of the genus Streptomyces are well-known for their capacity to synthesize a vast repertoire of secondary metabolites, including many useful antibiotics and proteins. Streptomyces clavuligerus is the producer of the medically important β-lactam antibiotics such as cephamycin C and the potent β-lactamase inhibitor clavulanic acid. The aspartate pathway of S. clavuligerus is an important primary metabolic pathway providing substrates for β-lactam synthesis. This pathway uses L-aspartic acid as the ...
