Listán Negro red grape variety in inajo, Lanzarote. he MycoBank no. is MB Introduction Yeasts are part of the natural microbial communities associated with fresh grapes and are the most important micro-organisms in wine production (Fleet et al., 2002).he yeast community on grapes is influenced by biotic and abiotic factors, including climatic conditions (mainly temperature and rainfall), geographical location and vineyard factors (age, size, grape variety and vintage year), vineyard treatments, physical grape damage, microbial vectors, microbial interactions and enzymic activities (Barata et al., 2012). Spontaneous alcoholic fermentation of grape must is characterized by the presence of a high number of yeast genera and species. In grape must and during the early phase of wine fermentation, apiculate species are the most frequent yeasts.

Indigenous yeast species from grapes and wine have been described in many wineproducing regions of the world. he Canary Islands, located in the Atlantic Ocean, near the ropic of Cancer, off the African coast of the Western Sahara, have a long tradition of viticulture. he Canarian archipelago comprises seven main islands together with a number of smaller islets. Most Canarian wines are produced in Lanzarote, enerife and La Palma. hese three islands have different bioclimatic and topographic characteristics. he relief is the main factor that affects the local rainfall distribution. In general, precipitation increases across the archipelago from east to west. enerife is situated near the centre of the archipelago and has the largest number of bioclimatic belts (26). Maximum rainfall is recorded on the northern side (up to 500 mm per year), while the southern side is drier (200 mm per year) (del-arco et al., 2006). La Palma, more oceanic and humid (rainfall exceeds 700 mm in most of the area), is the north-westernmost of the Canary Islands and has a wide variety of habitats (23 bioclimatics belts) (del-arco et al., 1999). Lanzarote is the northeasternmost and closest island to Africa coast (100 km). he low altitude does not allow the development of trade wind clouds. herefore, annual precipitation is below 200 mm and a limited number of bioclimatic belts (8) are defined (Reyes-Betancort et al., 2001) G 2013 IUMS Printed in Great Britain On: hu, 23 Nov :01:59

2 Lachancea lanzarotensis sp. nov. During a study of yeast communities associated with grape berries in vineyards and wineries in Lanzarote, enerife and La Palma (Canary Islands, Spain), conventional taxonomic tests and routine PCR restriction fragment length polymorphism analysis of the rdna 5.8S-internal transcribed spacer region (PCR-IS-RFLP) were used for identification. A group of novel yeast strains with identical PCR-IS-RFLP patterns was detected in Lanzarote. Analysis of D1/D2 domains of the large subunit (LSU) rdna and the 5.8-IS sequences of seven isolates indicated that these strains represented a distinct species closely related to Lachancea meyersii and Lachancea nothofagi. On the basis of phenotypic and phylogenetic analysis, a novel species of Lachancea, Lachancea lanzarotensis sp. nov., is proposed. Methods Sample collection and yeasts isolation. Collections were conducted in vineyards and wineries located in different bioclimatic conditions of the Canary Islands. Samples of healthy grapes and wineries were obtained from Lanzarote, enerife and La Palma. Grapes from 34 vineyards and samples from 23 wineries were collected during the 2009 harvest season, taking into account the bioclimatic factors of each island. In enerife, bunches were harvested from 18 vineyards belonging to three different zones and seven different bioclimatic belts ranging from 60 to 1175 m above sea level (m.a.s.l.). Vineyards sampled from this island are included in three wine-growing areas with Denominación de Origen. In La Palma, bunches were harvested from eight vineyards corresponding to three winemaking regions and four different bioclimatic belts ranging from 365 to 1180 m.a.s.l. Samples from Lanzarote were obtained from eight vineyards belonging to three winemaking regions and two different bioclimatic belts ranging from 188 to 390 m.a.s.l. en grape bunches each from red (Listán Negro) and white grape varieties (Listán Blanco, in enerife and La Palma or Malvasía, in Lanzarote) were randomly and aseptically collected from each vineyard and stored in sterile plastic bags. All the samples were kept cool during transport to the laboratory and were then directly processed. Each grape bunch was homogenized in a Stomacher for 2 min and 100 ml of the resulting must was plated on Dichloran Rose Bengal Chloramphenicol agar (DRBC) plates and incubated at 25 uc for 48 h. A total of ten yeast colonies from each plate (corresponding to each bunch) were randomly isolated. In addition a pool of musts elaborated with ten bunches from each variety and vineyard was made. From each pool, aseptic microvinifications were performed in 450 ml sterile bottles with 200 ml must. At the end of the fermentation process, 40 random yeast colonies obtained in DRBC were isolated from each microvinification. Wineries samples were obtained at the beginning, middle and end of the fermentation process, from the same regions described above. From each sample 40 random yeast colonies were isolated from DRBC medium. Subcultivations were performed on YPD agar at 25 uc for 3 days and were subsequently preserved in 30 % (w/v) glycerol at 280 uc. Yeast identification and characterization. Conventional taxonomic tests and routine PCR-IS-RFLP (Esteve-Zarzoso et al., 1999) were used for identification. A group of novel yeast strains with identical PCR-IS-RFLP patterns were detected in samples from Lanzarote and seven strains were selected for phenotypic characterization and sequence analysis (able 1). Physiological, biochemical and ascospore examination of the yeasts were carried out as described by Yarrow (1998). For Gorodkowa and V8 agar media, used to induce the sporulation, two different formulations of each were used: Gorodkowa A agar (0.1 % glucose, 0.5 % NaCl, 1 % peptone, 2 % agar), Gorodkowa B agar (0.25 % glucose, 0.5 % NaCl, 1 % malt extract, 2 % agar), Vegetable juice agar 1 (50 % V8 vegetable juice, 0.7 % yeast extract, 2 % agar) and V8 juice agar (Samson et al., 2010) (17.5 % V8 vegetable juice, 0.3 % CaCO 3, % ZnSO 4 7H 2 O, % CuSO 4 5H 2 O, 2 % agar).

3 S. S. González, J. Alcoba-Flórez and F. Laich tests were performed at 25 uc in duplicate and results were recorded after 1, 2 and 3 weeks. DNA sequence analysis. Nucleotide sequences of the D1/D2 domain of the LSU rdna gene and 5.8S-IS region of the strains L2C-15, CMV1-7, GMV1-4, GMV1-7, FLN2-4, 5BA-1 and 12BA-11 were determined using the methods described by Kurtzman & Robnett (1998). Sequences were deposited in the GenBank database and the strains were deposited in the CBS and CEC culture collections as shown in able 1. Comparisons with sequences from GenBank were performed using BLASN (Altschul et al., 1997). he sequences were initially aligned using the multiple alignment program CLUSAL W version 2.0 (Larkin et al., 2007). he phylogenetic tree was constructed using the neighbour-joining method (based on 1000 bootstrap iterations) in MEGA version 5 software (amura et al., 2011). Results and Discussion All strains tested exhibited similar physiological and morphological characteristics. However some differences were observed between strains in fermentation and assimilation tests for certain compounds. Strain GMV1-4 fermented D-galactose and a,a,-trehalose, but strains L2C- 15, GMV1-7, 12BA-11, 5BA-1, FLN2-4 and CMV1-9 were not fermentative. Strain L2C-15 did not assimilate xylitol, but the other strains did. Strain GMV1-7 was positive for assimilation of 2-keto-D-gluconate, but the other strains were negative. Strains GMV1-7, CMV1-9, GMV1-4, FLN2-4 were positive for growth in ethanol, but strains L2C-15, 12BA-11 and 5BA-1 had a weak growth. AcomparisonofchemotaxonomicpropertiesofL. lanzarotensis sp. nov. with those of other recognized species of the genus Lachancea are shown in able 2. L. lanzarotensis sp. nov., L. meyersii and L. nothofagi, displayed similar morphological and physiological characteristics. However, L. lanzarotensis sp. nov. could be distinguished from L. meyersii by its ability to assimilate D-galactose and from L. nothofagi by the ability to assimilate ethanol as a sole carbon source. For accurate identification of these species, sequencing of the 5.8S-IS rdna regions is needed. As an alternative to sequencing, a restriction analysis PCR-IS- RFLP can be performed. Restriction of the 5.8S-IS rdna regions with enzymes HinfI or DdeIseparatesL. lanzarotensis sp. nov. from L. meyersii and L. nothofagi. he three species have the same amplified product size (680 bp) with primers IS1 and IS4. With the enzyme HinfI the PCR-IS-RFLP pattern of L. lanzarotensis sp. nov. has five fragments ( bp), while L. meyersii and L. nothofagi have four fragments ( bp). With the enzyme DdeI L. lanzarotensis sp. nov. produces two fragments ( bp), while L. meyersii and L. nothofagi produce three fragments ( bp). he PCR-IS-RFLP technique is reproducible, rapid and easy to use for yeast species identification. his study also demonstrates its potential use in the detection of possible new species during yeast population diversity analysis. he seven strains were sequenced in the D1/D2 domain of the LSU rdna gene. Strains L2C-15, GMV1-4, GMV1-7 and CMV1-9 were found to share identical sequences, able 2.

A similar analysis was performed by 5.8S-IS rdna sequencing and in this case all the isolates had identical sequences. he phylogenetic tree constructed using the neighbourjoining method based on D1/D2 sequences showed that the novel species clustered with L. meyersii NRRL Y (GenBank accession no. AY645656) and L. nothofagi NRRL Y (GQ411403) (Fig. 1). Strain L2C-15 showed 98.3 % sequence similarity (8 substitutions+2 gaps) with L. meyersii and 97.3 % sequence similarity (16 substitutions) with L. nothofagi. A similar analysis was performed with the 5.8S-IS rdna sequences and the results demonstrated that 5.8S-IS tree was congruent with D1/ D2 tree. In the case of IS locus, strain L2C-15 showed 22 (96.24 % sequence similarity with 2 gaps) and 29 (95.05 % sequence similarity with 3 gaps) substitutions with L. meyersii and L. nothofagi, respectively. BLASN analysis of the nucleotide sequence of the D1/D2 domain of strain L2C-15 with the closest phylogenetic relatives retrieved from the GenBank database showed an identical sequence with Lachancea sp.

EF463105) isolated by van der Walt from garden soil in South Africa (Fig. 1). According to Kurtzman & Robnett (1998), yeast strains with 0 3 nt difference are conspecific or sister species, for this reason and using the proposed phenetic standard these isolates could be considered conspecific. Lachance (2011) discusses in detail the phylogenetic position of strain CBS 6924 in the genus Lachancea, and concludes that this strain deposited in 1975 by van der Walt as a specimen of Kluyveromyces thermotolerans is closely related to L. meyersii, but it is unclear whether it represents a distinct species. According to our phylogenetic tree constructed with the sequences available in GenBank (D1/D2 and 5.8S-IS) this strain could be considered conspecific with the proposed species. However this investigation did not attempt to revise previous taxonomy. Isolation of the strains of L. lanzarotensis sp. nov. only from Lanzarote could probably indicate that the proposed species has better capacity for adaptation or tolerance to desertic bioclimatic conditions. However, in enerife and La Palma samples were obtained from xeric bioclimatic areas on the southern sides of these islands and the proposed species was not detected. For this reason, it is probable that the population of this species is lower in enerife and La Palma, and the sampling protocol employed (10 randomly isolated colonies per bunch) did not allow detection. Also, it must be remembered that this species was isolated by other authors from grapes, plants and soil in different environments (Portugal, aiwan and South Africa), which shows the potential distribution and adaptability in distinct climatic regions. Based on phenotypic and phylogenetic analysis, strains L2C- 15, GMV1-4, GMV1-7, CMV1-9, 5BA-1, FLN2-4 and 12BA-11 represent a novel species of the genus Lachancea, for which the name Lachancea lanzarotensis sp. nov., is proposed.
