Cell Immobilization Technique for the Enhanced Removal of Lindane Using Streptomyces Strains Isolated from Northwestern Argentina

In recent years, as a consequence of the re-evaluation of the role of non-Saccharomyces yeasts, several studies have been conducted on the use of controlled mixed fermentations with Saccharomyces and different non-Saccharomyces yeast species from the winemaking environment. To benefit from the metabolic particularities of some non-Saccharomyces yeasts, the management of a non-Saccharomyces strain in mixed fermentation is a crucial step, in particular the use of procedures addressed to increase the persistence of non-Saccharomyces strains during the fermentative process. The use of microencapsulation for cell immobilization might represent a strategy for enhancing the competitiveness of non-Saccharomyces yeasts during mixed fermentation. This study was aimed to assess the fermentative performance of a mixed starter culture, composed by a wild Hanseniaspora osmophila strain (ND1) and a commercial Saccharomyces cerevisiae strain (EC1118). For this purpose, free and microencapsulated cells of ND1 strain were tested in co-culture with EC1118 during mixed fermentations in order to evaluate the effect of the microencapsulation on fermentative behavior of mixed starter and final wine composition. The data have shown that H. osmophila cell formulation affects the persistence of both ND1 and EC1118 strains during fermentations and microencapsulation resulted in a suitable system to increase the fermentative efficiency of ND1 strain during mixed starter fermentation.

Plant Data

The femoralis species group of the genus Blepharoneura is revised. The following 42 species, including 32 new species, are recognized: amplihyalina, n. sp. (northwestern Argentina), apaapa, n. sp. (Bolivia), aspiculosa, n. sp. (Mexico), bidigitata, n. sp. (southern Brazil), bipunctata, n. sp. (Ecuador), biseriata Wulp (Mexico), bivittata, n. sp. (Nicaragua, Costa Rica), brevivittata, n. sp. (Costa Rica to Peru), chaconi, n. sp. (Costa Rica), cornelli, n. sp. (Costa Rica), cyclantherae, n. sp. (Mexico), femoralis Wulp (Mexico to Brazil), fernandezi, n. sp. (Venezuela, northern Brazil), furcifer Hendel (Venezuela to Bolivia and Brazil), hirsuta Bates (Venezuela, Guyana, Brazil), hyalinella, n. sp. (Bolivia), io Giglio-Tos (Mexico), isolata, n. sp. (Guatemala), lutea, n. sp. (Costa Rica), macwilliamsae, n. sp. (Costa Rica), marshalli, n. sp. (northwestern Argentina), mexicana, n. sp. (Guatemala, Mexico), mikenoltei, n. sp. (Costa Rica), multipunctata, n. sp. (Ecuador), nigriapex, n. sp. (Bolivia), nigrifemur, n. sp. (Bolivia), osmundsonae, n. sp. (Mexico), punctistigma, n. sp. (Mexico to Costa Rica), quadristriata Wulp (Mexico to Costa Rica; possibly Colombia), quetzali, n. sp. (Guatemala), regina Giglio-Tos (Mexico), rupta (Wulp) (Mexico to Costa Rica), ruptafascia, n. sp. (Ecuador), septemdigitata, n. sp. (Peru, Bolivia), sinepuncta, n. sp. (Costa Rica), splendida Giglio-Tos (Mexico to Ecuador), tau, n. sp. (Costa Rica), thetis Hendel (southern Brazil), unifasciata, n. sp. (Ecuador), variabilis, n. sp. (Mexico), wasbaueri, n. sp. (Ecuador), and zumbadoi, n. sp. (Costa Rica). Blepharoneura amazonensis Lima & Leite, 1952 is considered a new synonym of B. hirsuta Bates, 1933, and a lectotype is designated for Blepharoneura furcifer Hendel, 1914. A key to species and phylogenetic analysis are provided, as well as descriptions, illustrations, distributions, and host plant data (as available) for each species.
