<p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />Dear Colleagues,</span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />The use of acetic acid bacteria (AAB) in foods, beverages and some industrial chemicals production as well as their potential for many new applications make them very important not only for modern industrial societies but for many ones in the developing world. Additionally, their special type of metabolism and the difficulties for unravelling their basic scientific aspects have become a challenge for many researchers throughout the world.</span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />In 2005, Prof. Paolo Giudici chaired the &ldquo;<a href="http://www.vinegars2005.com/" target="_blank">Vinegar and Acetic Bacteria. International Symposium</a>&rdquo; first meeting devoted to acetic acid bacteria with special interest in vinegar, traditionally, their most important product. Subsequently, in 2008, Prof. Kazunobu Matsushita had the responsibility of organizing the &ldquo;<a href="http://nodaiweb.university.jp/aab/" target="_blank">Second International Conference on Acetic Acid Bacteria</a>&rdquo;. Parallel specific conferences on vinegar research, fostered by The Vinegar Research Network (&ldquo;<a href="http://www.uco.es/aab2012/Download_Area/primeras_jornadas_vinagre.pdf" target="_blank">Primeras Jornadas de I+d+I en la Elaboraci&oacute;n de Vinagres de Vino</a>&rdquo; and &ldquo;<a href="http://www.uco.es/vinagres2006/home.htm" target="_blank">Second Symposium on Research+Development+Innovation for Vinegar Production</a>&rdquo;) were held in Spain during 2003 and 2006 chaired by Prof. Albert Mas and Prof. Isidoro Garc&iacute;a in Tarragona and Cordoba respectively.</span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />The upcoming meeting: &ldquo;<strong>Third International Conference on Acetic Acid Bacteria. Vinegar and Other products</strong>&rdquo;, will be held in Cordoba, Spain, during April 17-20, 2012. As responsible of this meeting as well as of the Network which promoted the aforementioned specific vinegar symposia, I suggest, for many reasons, from now on to combine both scientific conferences. So, the main objective of this Conference is to provide scientists, engineers, companies and any others interested in a platform for presenting latest research results, interchange and discussion of ideas, to establish new contacts and collaborations and exploring the development of new processes based on the capabilities of these bacteria.</span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />The Organizing and Scientific Committees have tried to prepare a <a href="http://www.uco.es/aab2012/index.php?option=com_content&amp;view=article&amp;id=34&amp;Itemid=33" target="_blank">scientific program</a> in order to organize and make easier the presentation of the main state-of-the-art scientific achievements regarding these microorganisms. The Conference will address the full spectrum of basic and applied research topics, including current trends and future applications.</span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />The Conference will be organized as the previous ones offering sessions for standard contributions, both oral and posters. The sessions should enable the delegates to attend also the presentations which are close to their speciality but outside their everyday interest.<br /></span></p><p style="text-align: justify; padding-left: 30px;">&nbsp;</p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;">The official conference language will be English, no simultaneous translation will be available to any other language.<br /></span></p><p style="text-align: justify; padding-left: 30px;">&nbsp;</p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;">Please, follow in the site (<a href="http://www.uco.es/aab2012/" target="_blank">http://www.uco.es/aab2012/</a>) many other details about our Conference and do not hesitate in contact us regarding any issue you consider important.<br /></span></p><p style="text-align: justify; padding-left: 30px;">&nbsp;</p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;">Finally, we are very pleased to invite you to join us in Cordoba at the spring of 2012 and participate in the "<strong>Third International Conference on Acetic Acid Bacteria. Vinegar and other products</strong>". We believe firmly that it will be a fruitful experience from many points of view and keep you in a very active and multidisciplinary field.<br /></span></p><p style="text-align: justify; padding-left: 30px;">&nbsp;</p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;">We look forward to seeing you in Cordoba in April of 2012<br /></span></p><p style="text-align: justify; padding-left: 30px;"><span style="font-size: small;"><br />Isidoro Garc&iacute;a Garc&iacute;a<br />Chairman<br /><strong>Third International Conference on Acetic Acid Bacteria.

ABSTRACT Thermotolerant microorganisms are useful for high-temperature fermentation. Several thermally adapted strains were previously obtained from Acetobacter pasteurianus in a nutrient-rich culture medium, while these adapted strains could not grow well at high temperature in the nutrient-poor practical culture medium, “rice moromi.” In this study, A. pasteurianus K-1034 originally capable of performing acetic acid fermentation in rice moromi was thermally adapted by experimental evolution using a “pseudo” rice moromi culture. The adapted strains thus obtained were confirmed to grow well in such the nutrient-poor media in flask or jar-fermentor culture up to 40 or 39 °C; the mutation sites of the strains were also determined. The high-temperature fermentation ability was also shown to be comparable with a low-nutrient adapted strain previously obtained. Using the practical fermentation system, “Acetofermenter,” acetic acid production was compared in the moromi culture; the results showed that the adapted strains efficiently perform practical vinegar production under high-temperature conditions.

Abstract Acetic acid bacteria (AAB) are valuable biocatalysts for which there is growing interest in understanding their basics including physiology and biochemistry. This is accompanied by growing demands for metabolic engineering of AAB to take advantage of their properties and to improve their biomanufacturing efficiencies. Controlled expression of target genes is key to fundamental and applied microbiological research. In order to get an overview of expression systems and their applications in AAB, we carried out a comprehensive literature search using the Web of Science Core Collection database. The Acetobacteraceae family currently comprises 49 genera. We found overall 6097 publications related to one or more AAB genera since 1973, when the first successful recombinant DNA experiments in Escherichia coli have been published. The use of plasmids in AAB began in 1985 and till today was reported for only nine out of the 49 AAB genera currently described. We found at least five major expression plasmid lineages and a multitude of further expression plasmids, almost all enabling only constitutive target gene expression. Only recently, two regulatable expression systems became available for AAB, an N-acyl homoserine lactone (AHL)-inducible system for Komagataeibacter rhaeticus and an l-arabinose-inducible system for Gluconobacter oxydans. Thus, after 35 years of constitutive target gene expression in AAB, we now have the first regulatable expression systems for AAB in hand and further regulatable expression systems for AAB can be expected. Key points • Literature search revealed developments and usage of expression systems in AAB. • Only recently 2 regulatable plasmid systems became available for only 2 AAB genera. • Further regulatable expression systems for AAB are in sight.
