PhD thesis, Wageningen University, Wageningen, NL (2014) With propositions, references and summaries in Dutch and English ISBN 978-94-6257-145-7 Abstract Microalgal pigments are regarded as natural alternatives for food colourants. To facilitate optimization of microalgae-based pigment production, this thesis aimed to obtain key insights in the pigment metabolism of phototrophic microalgae, with the main focus on secondary carotenoids. Different microalgal groups each possess their own set of primary pigments. Besides, a selected group of green algae (Chlorophytes) accumulate secondary pigments (secondary carotenoids) when exposed to oversaturating light conditions. -
I Topic - Algal Pigments and Algal Classification(ALGAE) Prepared by –Prof.(Dr.)Jainendra Kumar Coordinated By: Prof.(Dr) Shyam Nandan Prasad
Course- M.Sc. Botany Part -I Paper -I Topic - Algal Pigments and algal Classification(ALGAE) Prepared by –Prof.(Dr.)Jainendra Kumar Coordinated by: Prof.(Dr) Shyam Nandan Prasad The algae were broadly divided by F.F.Fritsch (1935) into eleven classes according to their colour - 1. Chlorophyceae or green algae 2. Xanthophyceae or yellow-green algae 3. Chrysophyceae 4. Bacillariophyceae or golden-brown algae 5. Cryptophyceae 6. Dinophyceae 7. Chloromonadineae 8. Eugleninae 9. Phaeophyceae or brown algae 10. Rhodophyceae or red algae, and 11. Myxophyceae or blue-green algae Normally, classification of algae is based on - 1. Nuclear Organization 2. Nature of Cell Wall Components 3. Pigmentation and Photosynthetic Apparatus The pigment is one of the most important criteria used in differentiation of classes in algae. The pigments in algae can be chlorophylls, carotenoids and biloproteins. These pigments are present in sac like structures called thylakoids. The thylakoids are arranged in stacks in the granum of the chloroplasts. Different groups of algae have different types of pigments and organization of thylakoids in chloroplast. The chlorophylls in algae are chlorophyll a, b, c, d and e types. Chlorophyll a is present in all classes of algae. Chlorophyll b is primary pigment of Chlorophyceae and Euglenineae. Chlorophyll c is found in Phaeophyceae and Cryptophyceae. Chlorophyll d is found in Rhodophyceae. Chlorophyll e is confined to Tribonema of Xanthophyceae. Pigments are chemical compounds which reflect only certain wavelengths of visible light. This makes them appear colourful. More important than their reflection of light is the ability of pigments to absorb certain wavelengths. Since each pigment reacts with only a narrow range of the spectrum, it is important for algae to produce pigments of different colours to capture more of the sun's energy. -

[email protected] (Received September 22, 2009; Accepted October 13, 2009) Abstract Chlorophyll synthesis is an ongoing requirement for photosynthesis and a ubiquitous, diagnostic characteristic of plants and algae amongst eukaryotes. However, we have discovered that chlorophyll a (Chla) is synthesized in the symbiotic chloroplasts of the sea slug, Elysia chlorotica, for at least 6 months after the slugs have been deprived of the algal source of the plastids, Vaucheria litorea. In addition, using transcriptome analysis and PCR with genomic DNA, we found 4 expressed genes for nuclear-encoded enzymes of the Chla synthesis pathway that have been horizontally transferred from the alga to the genomic DNA of the sea slug. -

Phytotoxicity assessments were conducted on the marine diatom Chaetoceros calcitrans using both the active ingredient and its formulated product (Opus). The 3-day EC50 using cell count was 2.31 mg/L for epoxiconazole active ingredient and 2.9 μg/L for epoxiconazole-formulated. The fungicide produced an increase of cellular volume, pigment (chlorophylls a, c, and carotenoids) content, ATP synthesis, and rates of photosynthesis and respiration. -

Received: 28 July 2014; in revised form: 31 August 2014 / Accepted: 1 September 2014 / Published: 10 September 2014 Abstract: Chlorophylls are a fundamental class of tetrapyrroles and function as the central reaction center, accessory and photoprotective pigments in photosynthesis. Their unique individual photochemical properties are a consequence of the tetrapyrrole macrocycle, the structural chemistry and coordination behavior of the phytochlorin system, and specific substituent pattern. They achieve their full potential in solar energy conversion by working in concert in highly complex, supramolecular structures such as the reaction centers and light-harvesting complexes of photobiology. The biochemical function of these structures depends on the controlled interplay of structural and functional principles of the apoprotein and pigment cofactors. -

Box 3640, 76021 Karlsruhe, Germany *S Supporting Information ABSTRACT: Laser-induced acoustic desorption (LIAD) has recently been established as a tool for analytical chemistry. It is capable of launching intact, neutral, or low charged molecules into a high vacuum environment. This makes it ideally suited to mass spectrometry. LIAD can be used with fragile biomolecules and very massive compounds alike. Here, we apply LIAD time- of-flight mass spectrometry (TOF-MS) to the natural biochromophores chlorophyll, hemin, bilirubin, and biliverdin and to high mass fluoroalkyl-functionalized porphyrins. We characterize the variation in the molecular fragmentation patterns as a function of the desorption and the VUV postionization laser intensity. We find that LIAD can produce molecular beams an order of magnitude slower than matrix- assisted laser desorption (MALD), although this depends on the substrate material. Using titanium foils we observe a most probable velocity of 20 m/s for functionalized molecules with a mass m = 10 000 Da.
