    An Integrative Approach Sheds New Light Onto the Systematics

    www.nature.com/scientificreports OPEN An integrative approach sheds new light onto the systematics and ecology of the widespread ciliate genus Coleps (Ciliophora, Prostomatea) Thomas Pröschold1*, Daniel Rieser1, Tatyana Darienko2, Laura Nachbaur1, Barbara Kammerlander1, Kuimei Qian1,3, Gianna Pitsch4, Estelle Patricia Bruni4,5, Zhishuai Qu6, Dominik Forster6, Cecilia Rad‑Menendez7, Thomas Posch4, Thorsten Stoeck6 & Bettina Sonntag1 Species of the genus Coleps are one of the most common planktonic ciliates in lake ecosystems. The study aimed to identify the phenotypic plasticity and genetic variability of diferent Coleps isolates from various water bodies and from culture collections. We used an integrative approach to study the strains by (i) cultivation in a suitable culture medium, (ii) screening of the morphological variability including the presence/absence of algal endosymbionts of living cells by light microscopy, (iii) sequencing of the SSU and ITS rDNA including secondary structures, (iv) assessment of their seasonal and spatial occurrence in two lakes over a one‑year cycle both from morphospecies counts and high‑ throughput sequencing (HTS), and, (v) proof of the co‑occurrence of Coleps and their endosymbiotic algae from HTS‑based network analyses in the two lakes. The Coleps strains showed a high phenotypic plasticity and low genetic variability. The algal endosymbiont in all studied strains was Micractinium conductrix and the mutualistic relationship turned out as facultative. Coleps is common in both lakes over the whole year in diferent depths and HTS has revealed that only one genotype respectively one species, C. viridis, was present in both lakes despite the diferent lifestyles (mixotrophic with green algal endosymbionts or heterotrophic without algae).

    Effects of Temperature, Light Intensity and Quality, Carbon Dioxide, and Culture Medium Nutrients on Growth and Lipid Production of Ettlia Oleoabundans

    Effects of Temperature, Light Intensity and Quality, Carbon Dioxide, and Culture Medium Nutrients on Growth and Lipid Production of Ettlia oleoabundans by Ying Yang A Dissertation Submitted to the Faculty of WORCESTER POLYTECHNIC INSTITUTE in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biology and Biotechnology by December 2013 Approved by: Dr. Pamela Weathers, Advisor Dr. Robert Thompson, Committee Member Dr. Luis Vidali, Committee Member Dr. Reeta Rao, Committee Member “A journey of a thousand miles begins with a single step.” — Lao Tzu (604 BC – 531 BC) ii Abstract Ettlia oleoabundans, a freshwater green microalga, was grown under different environmental conditions to study its growth, lipid yield and quality for a better understanding of the fundamental physiology of this oleaginous species. E. oleoabundans showed steady increase in biomass under low temperature and low light intensity, and at high temperature lipid cell content significantly increased independent of nitrate depletion. Studies on light quality showed that red light treatment did not change the biomass concentration, but stimulated lipid yield especially oleic acid, the most desirable biodiesel precursor. Moreover, no photoreversibility in lipid production was observed when applying alternating short-term red and far-red lights, which left the phytochrome effect still an open question. In addition, carbon dioxide enrichment via an air sparging system significantly boosted exponential growth and increased carbon conversion efficiency. Finally, a practical study demonstrated the feasibility of growing E. oleoabundans for high lipid production using a diluted agricultural anaerobic waste effluent as the medium. Together, these studies showed the potential of E. oleoabundans as a promising high yield feedstock for the production of high quality biodiesel.

Jahanzeb College Swat, Pakistan 2Department of Biotechnology, Quaid-e-Azam University Islamabad, Pakistan 3Pakistan Museum of Natural History, Islamabad, Pakistan Abstract Fifty six genera of green algae were collected from ten different localities of District Swat, belonging to 25 families and 9 genera of Chlorophyta from December 2006 August 2008. Family Oocystaceae with 39 species was most commonly found, next to it were families Scenedesmaceae with18 species and Desmidiaceae with 14 species. The genera Oocystis and Tetraedron were represented by 10 species and Cosmarium with 7 species occurred most commonly. Among the recorded genera 13 (23.2%) were Unicellular, 25 (44.6%) were Colonial, 9 (16.7%) were Unbranched filamentous, 4 (7.1%) were branched filamentous, 1 (1.7%) was Pseudofilamentous, 1 (1.7%) was Mesh-like, 2 (3.5%) were Heterotrichous and 1 (1.7%) was with Irregular amorphous thallus. Highest proportion of Chlorophycean members was recorded from Kanju area 89 and lowest was recorded from Kalam 69. Introduction Results and Discussion The Valley of Swat a part of Malakand Division covers Fifty six genera containing 138 species belonging to 25 5737 square kilometers (estimated). The elevation of the families and 9 orders have been collected from various fresh valley is 630 to 3000m above sea level. Swat is located at a water habitats. Collected algal members were identified up to distance of 170 km from Peshawar and 270 km from Federal species level.

The aim of the study was to identify green algal symbionts of P. bursaria originating from distant geographical locations and to answer the question of whether the occurrence of en- dosymbiont taxa was correlated with a specific ciliate syngen (sexually separated sibling group). In a comparative analysis, we investigated 43 P. bursaria symbiont strains based on molecular features. Three DNA fragments were sequenced: two from the nuclear genomes—a fragment of the ITS1-5.8S rDNA-ITS2 region and a fragment of the gene encoding large subunit ribosomal RNA (28S rDNA), Citation: Greczek-Stachura, M.; as well as a fragment of the plastid genome comprising the 30rpl36-50infA genes.
