The key to Received 27 June 2013 economic algal biomass production is to optimize the growth conditions. This study presents the effect of Received in revised form 6 November 2013 light wavelengths and growth medium composition on the growth of Chlorella vulgaris. Different light Accepted 6 November 2013 wavelengths [blue, clear (white), green, and red] were used to test their effect on algal growth. Growth media formulations were varied to optimize the growth media composition for maximized algal biomass Keywords: production. Experimental study was conducted in three phases to evaluate: (1) the effect of different Nutrient optimization light wavelengths; (2) the effect of the recommended growth medium at 25%, 50%, and 100% of Growth rates suggested composition; and (3) the effect of nutrient concentrations (nitrogen and phosphorous). The Chlorella vulgaris Light effect effect of these factors was evaluated through specific algal growth rates and volumetric biomass Volumetric biomass productivity productivities during the entire growth period. In this study, blue light performed better (higher growth rate and biomass productivity) at longer growth periods (10–14 days) compared to clear, red and green light wavelengths. The growth media and nutrient effect results indicate that the growth of C.

  • Non-Axenic Microalgae Cultivation in Space – Challenges for the Membrane Μgpbr of the ISS Experiment PBR@LSR
    48th International Conference on Environmental Systems ICES-2018-186 8-12 July 2018, Albuquerque, New Mexico Non-axenic microalgae cultivation in space – Challenges for the membrane µgPBR of the ISS experiment PBR@LSR Harald Helisch1, Stefan Belz2, Jochen Keppler3, Gisela Detrell4, Norbert Henn5, Stefanos Fasoulas6, Reinhold Ewald7 Institute of Space Systems, University of Stuttgart, Germany and Oliver Angerer8 German Aerospace Center (DLR), Bonn, Germany Keywords: PBR@LSR, ISS experiment, microalgae, Chlorella vulgaris, long-term cultivation, biofilm The spaceflight experiment PBR@LSR (Photobioreactor at the Life Support Rack) shall demonstrate for the first time the technology and performance of a hybrid life support system – a combination of physico-chemical and biotechnological components – under real space conditions during an operation period of 180 days. To be launched to the International Space Station (ISS) in 2018, PBR@LSR combines the carbon dioxide (CO2) concentrator of ESA’s Life Support Rack (LSR) with an advanced microalgae photobioreactor (PBR). Accommodated in the Destiny module, LSR will concentrate CO2 from the cabin atmosphere. A dedicated interface allows the utilization of the highly concentrated surplus CO2 for the cultivation of the green microalgae species Chlorella vulgaris. Current research at the University of Stuttgart focuses on the fundamental investigation and optimization of non-axenic cultivation processes in µg capable membrane PBRs. This includes the characterization of influences of accompanying bacteria on the non-axenic microalgae culture stability within the PBR suspension loop, photosynthetic capacity as well as overall biomass composition. This paper discusses in general possible influences of emerging bacteria- or algae induced biofilm formation and cell clustering due to non-axenic processing on the long term functionality of µg adapted PBR systems, e.g.

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.

  • New Observations on Green Hydra Symbiosis
    Folia biologica (Kraków), vol. 55 (2007), No 1-2 Short Note New Observations on Green Hydra Symbiosis Goran KOVAÈEVIÆ, Mirjana KALAFATIÆ and Nikola LJUBEŠIÆ Accepted September 20, 2006 KOVAÈEVIÆ G., KALAFATIÆ M., LJUBEŠIÆ N. 2007. New observations on green hydra symbiosis. Folia biol. (Kraków) 55: 77-79. New observations on green hydra symbiosis are described. Herbicide norflurazon was chosen as a «trigger» for analysis of these observations. Green hydra (Hydra viridissima Pallas, 1766) is a typical example of endosymbiosis. In its gastrodermal myoeptihelial cells it contains individuals of Chlorella vulgaris Beij. (KESSLER &HUSS 1992). Ultrastructural changes were observed by means of TEM. The newly described morphological features of green hydra symbiosis included a widening of the perialgal space, missing symbiosomes and joining of the existing perialgal spaces. Also, on the basis of the newly described mechanisms, the recovery of green hydra after a period of intoxication was explained. The final result of the disturbed symbiosis between hydra and algae was the reassembly of the endosymbiosis in surviving individuals. Key words: Green hydra, Chlorella, perialgal space, symbiosome, symbiosis reassembly.

  • Predator-Prey Interactions Between the Ciliate Blepharisma Americanum
    Vol. 83: 211–224, 2019 AQUATIC MICROBIAL ECOLOGY Published online September 19 https://doi.org/10.3354/ame01913 Aquat Microb Ecol OPENPEN ACCESSCCESS Predator−prey interactions between the ciliate Blepharisma americanum and toxic (Microcystis spp.) and non-toxic (Chlorella vulgaris, Microcystis sp.) photosynthetic microbes Ian J. Chapman1,2, Daniel J. Franklin1, Andrew D. Turner3, Eddie J. A. McCarthy1, Genoveva F. Esteban1,* 1Bournemouth University, Department of Life and Environmental Sciences, Faculty of Science and Technology, Dorset, BH12 5BB, UK 2NSW Shellfish Program, NSW Food Authority, Taree, NSW 2430, Australia 3Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Weymouth, Dorset, DT4 8UB, UK ABSTRACT: Despite free-living protozoa being a major factor in modifying aquatic autotrophic biomass, ciliate−cyanobacteria interactions and their functional ecological roles have been poorly described, especially with toxic cyanobacteria. Trophic relationships have been neglected and grazing experiments give contradictory evidence when toxic taxa such as Microcystis are in - volved. Here, 2 toxic Microcystis strains (containing microcystins), 1 non-toxic Microcystis strain and a non-toxic green alga, Chlorella vulgaris, were used to investigate predator−prey interac- tions with a phagotrophic ciliate, Blepharisma americanum. Flow cytometric analysis for micro- algal measurements and a rapid ultra high performance liquid chromatography-tandem mass spectrometry protocol to quantify microcystins showed that non-toxic photosynthetic microbes were significantly grazed by B. americanum, which sustained ciliate populations. In contrast, despite constant ingestion of toxic Microcystis, rapid egestion of cells occurred. The lack of diges- tion resulted in no significant control of toxic cyanobacteria densities, a complete reduction in cil- iate numbers, and no observable encystment or cannibalistic behaviour (gigantism).

Many scientific works and industrial exploitations have thus been set up. These developments have often highlighted the need to intensify the processes for biomass production in photo-autotrophy and exploit all the microalgae value including ExoPolySaccharides (EPS). Indeed, the bottlenecks limiting the development of low value products from microalgae are not only linked to biology but also to biological engineering problems including harvesting, recycling of culture media, photoproduction, and biorefinery. Even respecting the so-called “Biorefinery Concept”, few applications had a chance to emerge and survive on the market.
