Diversity of yeast strains of the genus Hanseniaspora in the winery environment: What is their involvement in grape must fermentation?

2015

Isolated yeast populations of Chardonnay grape must during spontaneous fermentation were compared to those isolated on grape berries and in a winery environment before the arrival of the harvest (air, floor, winery equipment) and in the air through time. Two genera of yeast, Hanseniaspora and Saccharomyces, were isolated in grape must and in the winery environment before the arrival of the harvest but not on grape berries. The genus Hanseniaspora represented 27% of isolates in the must and 35% of isolates in the winery environment. The isolates of these two species were discriminated at the strain level by Fourier transform infrared spectroscopy. The diversity of these strains observed in t…

Secular growth changes in the stature and weight of Amerindian schoolchildren and adults in the Chilean Andes, 1972-1987.

1997

A positive secular trend for stature and weight is evident in rural Aymara-speaking Indians of the Parinacota Province (>3,000 m) in the northern Chilean Andes. The study is based on two cross-sectional growth surveys carried out in 1972 and 1987. In the survey of 1972, which was undertaken by other authors, a sample of 190 individuals was considered. The 1987 survey, performed by the present author, comprises a sample of 170 Indians. Both children and adults of each sex, ages 6-29 years, are included. Secular comparisons of age-grouped means indicate a secular increase in stature and weight in Aymara children, adolescents, and adults in the Parinacota Province between 1972 and 1987. The Ay…

Cloudiness and Sunshine

1988

Records on mean monthly and annual cloudiness are contained in the climate tables (see Appendix). Despite regional gaps of data sources, the attempt was nevertheless made to work out some principal observations on cloudiness.

Spatiotemporal Variations in the Abundance and Structure of Denitrifier Communities in Sediments Differing in Nitrate Content

2017

Spatial and temporal variations related to hydric seasonality in abundance and diversity of denitrifier communities were examined in sediments taken from two sites differing in nitrate concentration along a stream Do&ntilde

Exploiting the Incomparability of Comparable Corpora for Contrastive Linguistics and Translation Studies

2013

For empirical research in translation studies and contrastive linguistics comparability across languages is an important and non-trivial issue, particularly, if we aim at quantifying differences and commonalities. We approach this problem by investigating the CroCo Corpus of English and German originals and translations in eight different registers concentrating on the (in)comparability of the different subcorpora. They are comparable across languages but incomparable in terms of functional, i.e. register, variation. A feature matrix is analysed to reveal differences and commonalities between the bilingually comparable texts (i.e. English and German originals) and the monolingually comparab…

A study of thyme germplasm in Sicily

2009

hyme is characteristic of the Mediterranean and is of interest for its multifunctional nature. It is widely used in seasoning and flavouring, in herbal products and cosmetics. The versatility of this species means it is also useful in the protection of areas prone to erosion or an ornamental plant when designing low-maintenance gardens. Thyme germplasm constitutes a large part of the wild flora in Sicily and is a potentially useful source of genetic variability. On the basis of this, in the two-year period from 2004-2005, research was carried out on wild thyme accessions. These were used to evaluate both its productivity and individual biotypes with the functional characteristics most sough…

Genetic diversity and relationships among Italian and foreign almond germplasm as revealed by microsatellite markers

2013

Abstract Italian germplasm is characterized by a wide diversity rapidly developed determining a massive genetic pool of cultivars in several growing areas. On the whole, regions of southern Italy, and in particular Sicily, were considered as one of the main trade routes along which almond was spread throughout the shores of the Mediterranean Sea. In this work, 9 SSR markers have been used to analyze 113 almond cultivars and accessions coming from ex-situ conservation, including most of almond genotypes spread in Sicily and Apulia and foreign cultivars from Mediterranean, American and Australian areas in order to determine the level of genetic diversity within Italian genotypes and elucidate…

Microsatellite marker-based genetic variability in Spanish rice cultivars and landraces

2010

The genetic relationships among japonica rice cultivars and landraces were studied. Most of them are of Spanish origin, and were developed and cultivated for varying time periods over more than a century. To uncover genetic diversity within each cultivar, we analysed 30 plants per cultivar or accession using 10 fluorescently labelled primer pairs for SSR markers. Six cultivars were included in the study, with accessions from four different regions of Spain of the traditional cultivar Bomba. A total of 37 alleles were detected with a mean of 3.7 alleles per locus. Polymorphism information content (PIC) ranged from 0 to 0.78 with an average of 0.51 per locus. Genetic diversity for cvs. Albufe…

Genetic diversity of Dioscorea dumetorum (Kunth) Pax using Amplified Fragment Length Polymorphisms (AFLP) and cpDNA

2010

We have utilized Amplified Fragment Length Polymorphisms (AFLP) in conjunction with chloroplast DNA (cpDNA) sequence data to study the genetic diversity in 53 accessions of Dioscorea dumetorum from six countries in West and Central Africa. Our results provide a comparison of the two marker systems with regards to their applicability to differentiate intraspecific genotypes and the grouping of the accessions based on localities of collection. A total of 1052 AFLP fragments (of which 94.1% were polymorphic) produced from twelve primer combinations indicate a relatively high level of polymorphism among the accessions. Three major genetic groups that do not strictly follow a geographic distribu…
