Lactobacillus plantarum isolated from cheese: production and partial characterization of bacteriocin B391Annals of Microbiology - Tập 67 - Trang 433-442 - 2017
Paulo Fernandes, Daniela Loureiro, Vitor Monteiro, Carla Ramos, Luis Augusto Nero, Svetoslav Dimitrov Todorov, Joana Santos Guerreiro
Lactobacillus plantarum B391, a strain isolated from an artisanal French cheese,
is a producer of a bacteriocin, expressing activity against Enterococcus
faecalis NCTC 775, Clostridium perfringens NCTC 13170 and several Listeria
monocytogenes strains. High stability was recorded after heat treatment at
121 °C for 20 min and when stored at 4 °C for more than 40 days. A challenge

Diversity and dynamics stability of bacterial community in traditional solid-state fermentation of Qishan vinegarAnnals of Microbiology - Tập 67 - Trang 703-713 - 2017
Xing Gan, Hanlan Tang, Dongdong Ye, Pan Li, Lixin Luo, Weifeng Lin
Qishan vinegar is a typical Chinese fermented cereal product that is prepared
using traditional solid-state fermentation (SSF) techniques. The final qualities
of the vinegar produced are closely related to the multiple bacteria present
during SSF. In the present study, the dynamics of microbial communities and
their abundance in Daqu and vinegar Pei were investigated by the combination of
high thr... hiện toàn bộ
Effect of feeding strategy on l-tryptophan production by recombinant Escherichia coliAnnals of Microbiology - Tập 62 - Trang 1625-1634 - 2012

Acetic acid is a primary inhibitory metabolite in Escherichia coli cultivation,
and is detrimental to bacterial growth and formation of desired products. The
effects of acetic acid on l-tryptophan production by recombinant E. coli were
evaluated in this study. Results indicated that growth of an
l-tryptophan-producing bacterium and l-tryptophan formation were inhibited
significantly by acetic acid... hiện toàn bộ
Định vị biomacromolecule trong tế bào vi khuẩn qua cơ chế khuếch tán và bắt giữ Dịch bởi AI Annals of Microbiology - Tập 63 - Trang 825-832 - 2013
Miguel Angel Pérez Rodriguez, Xianwu Guo
Định vị subcellular của biomacromolecules ( nucleotide và protein) là cơ sở cho
chức năng đúng đắn của chúng trong tế bào vi khuẩn. Một mô hình để giải thích sự
định vị của biomacromolecules, đặc biệt là protein, là "khuếch tán và bắt giữ".
Trong mô hình này, protein được định vị bằng cách khuếch tán qua tế bào chất
hoặc màng cho đến khi gắn với một protein hoặc các protein khác đã được tích tụ

Dynamics of Saccharomyces cerevisiae populations in controlled and spontaneous fermentations for Franciacorta D.O.C.G. base wine productionAnnals of Microbiology - Tập 64 - Trang 639-651 - 2013
Ileana Vigentini, Vincenzo Fabrizio, Monica Faccincani, Claudia Picozzi, Andrea Comasio, Roberto Foschino
The evolution of the yeast populations was investigated during controlled and
spontaneous fermentations of Chardonnay must in two Franciacorta wineries (A and
B) that used the same starter culture. Two hundred and three isolates were
collected and identified as Saccharomyces cerevisiae (97.5 %), Pichia
membranifaciens (2.0 %) and Hanseniaspora vinae (0.5 %) through the analyses of
ITS rDNA region ... hiện toàn bộ
Identification and probiotic properties of lactobacilli isolated from two different fermented beveragesAnnals of Microbiology - Tập 69 - Trang 1557-1565 - 2019

Scientific information regarding the microbial content and functional aspects of
fermented beverages traditionally produced in certain parts of Europe are
scarce. However, such products are believed to have some health benefits and
might contain functional bacterial strains, such as probiotics. The aim of the
study was to identify such lactic acid bacteria strains isolated from water
kefir and, fo... hiện toàn bộ
Identification of multi-resistant strains of Acinetobacter baumannii from an ICU in Greece using sequence-based typing and PFGEAnnals of Microbiology - Tập 61 - Trang 871-877 - 2011

Acinetobacter baumannii has emerged as an important nosocomial pathogen in many
European countries, including Greece. In this study, we analysed 20
multi-resistant A. baumannii strains, derived from the First intensive care unit
(ICU) of the General Hospital “G. Papanikolaou”, in order to investigate their
epidemiology. Samples were taken from the pharynx and perineum of ICU patients
for determina... hiện toàn bộ
