Borenberg, Fredrik. "Biofiltrering av luft förorenad med terpener : Biofiltration of air polluted with terpenes." Thesis, Växjö University, School of Technology and Design, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:vxu:diva-2000.
Utsläpp av lättflyktiga organiska föreningar (VOC) är ett växande mijlöproblem. Biofiltrering är ett relativt billigt sätt att rena luft förorenad med VOC. Biofiltrering har också en fördel i att föroreningen helt bryts ned och inte endast övergår i en annan form. Rapporten beskriver arbetet kring två biofilter av kolonntyp. Mikroberna som användes kom från främst träflis och jord. Som förorening användes limonen och α-pinen. Analys skedde med gaskromatografi.
Vidare undersöktes om närvaro av silikonolja i filterbädden påverkade resultatet Reningskapaciteten uppgick i filtret utan olja till ca 10 - 12 g/m3.h under de första 25 dagarna i drift och ökade därefter till ca 15 - 20 g/m3.h. Motsvarande data för det oljeberikade filtret är ca 15 - 20 g/m3.h i båda fallen
Emissions of volatile organic compounds are a growing environmental problem. Biofiltration is a relatively cost efficient method to purify air polluted with VOC:s. Biofiltraion also has the benefit of completely degrading the pollutants rather than just transferring them into another phase/form. This report describes the work on two biofilters of column type. The microbes used were extracted from wood chips and soil. As pollutants limonene and α–pinene were used.
Furthermore, it was investigated how the presence of silicone oil in the filter bed affected the filtering results. The filtering capacity in the non oil enriched filter was during the first 25days 10-12 g/m3h and thereafter some 15-20 g/m3h. The efficiency of the oil enriched filter was stable at 15-20 g/m3h.

Complejos aminotrifenolatos de Al (III) y Fe (III) combinados con un nucleófilo han sido investigados como catalizadores binarios en la reacción de ROCOP para la obtención de polímeros bio-renovables perfectamente alternados. Se ha estudiado el acoplamiento de óxido de limonene y dióxido de carbono para la obtención de policarbonatos alternados. Este sistema catalítico fue capaz de producir polímeros trans estereoregulares a partir de óxido de limoneno cis. El catalizador de Al (III) muestra potencial para transformar ambos isómeros del óxido de limonene, con niveles de conversión altos, sin necesidad de usar disolvente. Además, hemos sintetizado seis anhídridos tricíclicos parcial o totalmente renovables y los hemos copolimerizado con óxido de propileno y óxido de ciclohexano. Cambiando ambos, epóxidos y anhídridos, hemos logrado variar la temperatura de transición vítrea de estos polímeros en 120 °C, desde 66 °C hasta la excepcional temperatura de 184 °C. Hemos investigado el uso de epóxidos derivados de terpenos (óxido de limoneno, óxido de careno, dióxido de limonene y oxido de menteno) para ROCOP en presencia de varios anhídridos aromáticos. Estas reacciones de copolimerización fueron llevadas a cabo usando aminotrifenolatos basados en Fe (III) y PPNCl permitiéndonos obtener poliesters semi-aromáticos parcialmente renovables con temperaturas de transición vítrea de 59 a 243 ºC. Finalmente, se han usado aminotrifenolatos de Al (III) y PPNCl para la preparación de una serie de biocarbonatos derivados de ácidos grasos. Este sistema catalítico permite convertir los époxidos derivados de ácidos grasos en ciclocarbonatos manteniendo un alto nivel de diastereoselectividad.
Aminotriphenolate Al (III) and and Fe (III) complexes combined with a nucleophile have been investigated as binary catalytic systems for ROCOP reactions to afford perfectly alternating bio-renewables polymers. The coupling of limonene oxide and carbon dioxide to obtain polycarbonates has been studied. These catalysts are able to produce stereoregular trans configured polymers from cis limonene oxide. The Al (III) catalyst shows the potential to transform both stereoisomers of limonene oxide with high conversion levels under neat conditions. Furthermore, we synthesized six partially or fully renewable tricyclic anhydrides and copolymerized them with propylene oxide and cyclohexene oxide. By varying both the epoxide and the anhydride, we were able to increase the Tg of the resulting polymers over nearly 120 °C from 66 °C to an exceptionally high 184 °C. We have investigated the use of terpene derived epoxides (limonene oxide, carene oxide, limonene dioxide and menthene oxide) for the ROCOP in the presence of various aromatic anhydrides. These copolymerization reactions were performed using Fe(III) based aminotriphenolate complex and PPNCl providing partially bio-based semi-aromatic polyesters with glass transition temperatures spanning from 59 to 243 ºC. Finally, Al (III) aminotriphenolate and PPNCl were used for the preparation of a series of fatty acid derived biocarbonates. This catalyst system allows to convert the fatty acid derived epoxides maintaining high levels of diastereospecificity.

Origanum vulgare L. ssp. vulgare plants were grown in a Paddy-Fan greenhouse, with 100% (complete), 75%, 50%, and 25% Hoagland and Arnon (1950) #2 nutrient solution. The objective of the study was to evaluate the influence of the complete nutrient solution with the various diluted solutions, with regards to the growth of the Origanum vulgare L. ssp. vulgare, its gas exchange, antioxidant potential, and chemical composition during its growth. At 20, 40, 60, 80 and 100 days after transplanting the seedlings to the nutrient solution the following observations were measured: dry matter of leaves (DML) and total (DMT), and leaf area of the leaves (AL). These measurements were used to evaluate the physiological index, leaf area ratio (LAR), leaf weight ratio (LWR), net assimilation rate (NAR), and relative growth rate (RGR). The exchange of gases was evaluated at 20, 45 and 85 days after transplantation. At 20, 40, 60, 80 and 100 days after transplantation, fresh samples of foliage were collected and frozen in liquid nitrogen. These samples were stored in a freezer for later analyzes of pigmentation, total flavonoids, total phenols, ascorbic acid, and antioxidant potential. The essential oil was evaluated at 60, 80 and 100 days after transplantation. The experiment was randomized with the following factors: four repetitions in a design 4x5 (4 treatments and 5 harvest timeframe) to evaluate the growth and biochemical results, 4x3 for exchange of gases and 3X3 for the analysis of essential oil composition. The results of this experiment indicates that the variation of the nutrient solution’s concentration can stimulate or inhibit the growth Origanum vulgare L. ssp. vulgare, particularly in more concentrated solutions. Plants grown with more concentrated solutions showed a decrease of DML, DMT and AL, which interfered with the physiological indices. Additionally, a reduction in the exchange of gases was present, as well as an increase in the ...

Resumo: O presente trabalho foi dividido em três partes todas relacionadas a química das relações entre os seres vivos. Na primeira parte do trabalho estudou-se a química da polinização de orquídeas da subtribo Maxillariinae em termos da composição dos voláteis e recompensas florais coletadas pelos polinizadores. Discutiu-se também os compostos envolvidos na atração dos polinizadores de Mormolyca ringens e Trigonidium obtusum. Identificou-se, nesta etapa uma série de compostos: hidrocarbonetos, terpenos, álcoois, aldeídos, cetonas, ésteres, etc. Em um segundo momento determinou-se a composição química do néctar de Spathodea campanulata (Bignoniaceae), uma planta relatada como tóxica. Identificou-se, além de carboidratos, compostos secundários como terpenos, esteróides e carboidratos acetilados. Também foram identificados os constituintes voláteis: 1-octen-3-ol e 1-octen-3-ona. Na última parte do trabalho explorou-se a modificação química das ceras de duas espécies de abelhas que estabeleceram uma relação de convivência em um mesmo ninho. A composição química das ceras de operárias de colônias puras e de colônias mistas de M. scutellaris apresentaram perfis químicos diferentes produzindo nas colônias puras uma série de n-alcanos e n-alcenos enquanto que a colônia mista apresentou elevado percentual de acetato de triacontanila. As ceras das colônias de M. rufiventris apresentaram variações nas proporções de hidrocarbonetos.
Abstract: This work is presented in three distincts parts, ali of them concerning the chemistry involved in inter-specific relations. In the first part we discuss the pollination chemistry of orchids, subtribe Maxillariinae, in terms of floral volatiles and rewards collected by polinators. It is also discussed the compounds involved in polinattors attraction by Mormlyca rigens and Trigonidium obtusum. At this stage we have identified hydrocarbons, terpenes, alcohols, aldehydes, ketones, esters, etc. In the second chapter we analyzed the chemical composition of Spathodea campanulata (Bignoniaceae) nectar. Occurence wich has been considered toxic, due to the dead insects inside the flower. Morever, we identified some secondary metabolites as terpenes, steroids and acetylated sugars. Volatiles compounds as 1-octen-3-ol and 1-octen-3-one were also identified. The last part explores the chemical modification in waxes from two bees species that established coexistence in the same nest. We compare the chemical modification of waxes from worker bees in pure and mixed colonies of Meliponia rufiventris and Melipona scutellaris. Revealing that the ratio of alkanes, alkenes, were altered in M. rufiventris colonies. M. scutellaris pure colonie produce alkanes and alkanes and the chemistry of mixed colonies were altered producing high ratio of triacontanyl acetate.

Resumo: A biotransformação de carotenóides é um campo de crescente interesse para a indústria de aromas, uma vez que podem ser obtidos compostos considerados como ¿naturais¿, de grande aplicabilidade industrial e que podem apresentar, em muitos casos, propriedades biológicas interessantes. Desta forma, o objetivo do presente trabalho foi efetuar um estudo de biotransformação de carotenóides seguida de uma otimização do processo, avaliar o uso de sub-produtos industriais para barateamento do processo, realizar a biotransformação de outros substratos terpênicos para formação de compostos voláteis e por fim, estudar as propriedades biológicas dos produtos voláteis derivados de carotenóides. O capítulo 1 apresenta uma revisão bilbiográfica sobre bio-oxidação de terpenos, focando especialmente no uso monoterpenos e b-caroteno como substrato. O capítulo 2 trata do isolamento de micro-organismos a partir de fontes naturais ricas em b-caroteno. Das mais de 400 linhagens avaliadas, cerca de 60 apresentaram um potencial para biotransformação de carotenóides, evidenciado por um halo de degradação característico formado ao redor da colônia inoculada em uma placa contendo b-caroteno. Em seguida, a técnica de microextração em fase sólida (SPME) foi usada para extração e concentração dos compostos voláteis formados na biotransformação pelas linhagens selecionadas, e os compostos foram identificados por CG-DIC e CG-EM. O estudo das variáveis envolvidas no processo de biotransformação de b-caroteno pela linhagem LB398APD é reportada no Capítulo 3. Para isso, um Placket-Burman (PB16) foi realizado inicialmente para seleção de variáveis, e seguindo o processo de planejamento experimental, um fatorial 22 com os parâmetros significativos do PB foi realizado. Em posse dos resultados da otimização, o Capítulo 4 retrata o uso de meios alternativos para o desenvolvimento de biomassa pela linhagem LB398APD. O micro-organismo possuiu um desenvolvimento em meio manipueira superior ao meio convencional, com condições ótimas do sistema alcançadas usando 60 % de manipueira, 30 °C e 300 rpm (produção de biomassa em 24h = 4,6g.L-1). Entretanto, quando glicerol foi usado como fonte de carbono, o desenvolvimento de biomassa não foi obtido com sucesso. Além dos ensaios usando b-caroteno como substrato, outros terpenos também foram avaliados com algumas linhagens fúngicas isoladas, e essa biotransformação é reportada no Capítulo 5. Carvona e carveol foram obtidos quando o limoneno foi usado como única fonte de carbono, e o uso de Paecilomyces sp. parece ser a primeira vez onde esse micro-organismo é reportado na literatura para ensaios e biotransformação. Por fim, o Capítulo 6 trata de alguns estudos ¿in vitro¿ com compostos de aromas derivados de carotenóides. Os resultados alcançados geram a possibilidade para esses compostos seres utilizados industrialmente como ¿aromas funcionais¿, pois apresentaram resultados extremamente interessantes quando esses terpenos foram usados em 12 células tumorais, representando resultados muitas vezes superiores ao controle positivo (doxorrubicina)
Abstract: The biotransformation of carotenoids is a field of growing interest to the flavor industry, once the compounds obtained can be labeled as "natural", with high industrial applicability and that may present, in many cases, interesting biological properties. Chapter 1 reviews a variety of techniques developed till the present days for the oxidation of terpenes, especially monoterpenes and ß-carotene, to volatile compounds. In sequence, Chapter 2 deals with the screening of microorganisms from natural sources rich in ß-carotene. Among more than 400 strains evaluated, 60 exhibited a potential for biotransformation of carotenoids, as evidenced by a characteristic degradation halo formed around the colonies inoculated on a plate containing ß-carotene. Afterwards, the solid phase microextraction technique (SPME) was used to extrain and concontrate the aroma compounds produced by the selected strains, and the analysis were conduced by GC-FID and GC-MS. The study of the variables involved in the biotransformation of ß- carotene by the LB398APD strain is reported in Chapter 3. For this, a Placket-Burman (PB16) was initially performed for the screening of the variables, and following the experimental design process, a 22 factor with the significant parameters selected in the PB was performed. In sequence, Chapter 4 shows the use of alternative culture media for the biomass development by the LB398APD strain. The microorganism demonstrated a development in the cassava wastewater media higher than in the conventional media, and the optimum system conditions were achieved by using 60 % of cassava wastewater, 30 °C and 300 rpm (biomass production in 24 hours = 4.6 gL-1). In addition to the tests using ß-carotene as substrate, other terpenes were also tested with some fungal strains, and this biotransformation is reported in Chapter 5. Carvone and carveol were obtained when limonene was used as the sole carbon source. The use of Paecilomyces sp. seems to be the first report in literature for biotransformation assays. Finally, Chapter 6 deals with some in vitro studies with carotenoids derived aroma compounds. The promising results create the possibility for such compounds to be used as "functional flavors"
