Dividing subpopulation of Escherichia coli in stationary phase
Publication date: Available online 14 February 2020Source: Research in MicrobiologyAuthor(s): Arvi Jõers, Eliis Liske, Tanel TensonAbstractThe bacterial growth cycle contains different phases: after the growth substrate is exhausted or the toxic waste products accumulate the growth stops. In this non-growing culture the number of colony forming bacteria remains constant or starts to decrease. It has been shown that during prolonged incubation there is constant growth and death of bacteria and certain mutant populations take over the culture. Here we show that the dynamic cell division and death balance can be obtained eve...

Amino acids are key substrates to Escherichia coli BW25113 for achieving high specific growth rate
Publication date: Available online 11 February 2020Source: Research in MicrobiologyAuthor(s): Andres Maser, Karl Peebo, Raivo Vilu, Ranno NahkuAbstractStudying substrate consumption in nutrient-rich conditions is challenging because often the growth medium includes undefined components like yeast extract or peptone. For clear and consistent results, it is necessary to use defined medium, where substrate utilization can be followed. In the present work, Escherichia coli BW25113 batch growth in a medium supplemented with 20 proteinogenic amino acids and glucose was studied. Focus was on the quantitative differences in substr...

Polyamine depletion has global effects on stress and virulence gene expression and affects HilA translation in Salmonella enterica serovar Typhimurium
Publication date: Available online 25 January 2020Source: Research in MicrobiologyAuthor(s): Priscila R. Guerra, Gang Liu, Sebastien Lemire, Arkadiusz Nawrockic, Egle Kudirkiene, Jakob Møller-Jensen, John E. Olsen, Lotte JelsbakAbstractPolyamines are small cationic amines required for modulating multiple cell process, including cell growth and DNA and RNA stability. In Salmonella polyamines are primarily synthesized from L-arginine or L-ornithine. Based on a previous study, which demonstrated that polyamines affect the expression of virulence gene in S. Typhimurium, we investigated the role of polyamines in the global gen...

Copper limiting threshold in the terrestrial ammonia oxidizing archaeon Nitrososphaera viennensis
This study explored the physiological response of the AOA soil isolate, Nitrososphaera viennensis (EN76T) to Cu-limiting conditions in order to approach its limiting threshold under laboratory conditions. The chelator TETA (1,4,8,11-tetraazacyclotetradecane N, N’, N’’, N’’’-tetraaceticacid hydrochloride hydrate) with selective affinity for Cu2+ was used to lower bioavailable Cu2+ in culture experiments as predicted by thermodynamic speciation calculations. Results show that N. viennensis is Cu-limited at concentrations ≤10-15 mol L-1 free Cu2+ compared to standard conditions (10-12 mol L-1). This Cu2+ limitin...

Biodiversity and richness shifts of mucosa-associated gut microbiota with progression of colorectal cancer
Publication date: Available online 24 January 2020Source: Research in MicrobiologyAuthor(s): Hong-Wei Pan, Lu-Tao Du, Wei Li, Yong-Mei Yang, Yi Zhang, Chuan-Xin WangAbstractThe host-associated gut microbiota is considered critical for the occurrence and progression of colorectal cancer (CRC); however, systematic evaluations of the changes in the biodiversity and richness of mucosa-associated gut microbiota with the development of CRC have been limited. Twenty-three paired samples from colorectal tumor sites and the surrounding non-tumor tissues were collected from stage I to IV CRC patients. The microbial compositions of t...

Escherichia coli O-antigen Capsule (Group 4) is Essential for Serum Resistance
Publication date: Available online 24 January 2020Source: Research in MicrobiologyAuthor(s): Dvora Biran, Ilan Rosenshine, Eliora Z. RonAbstractMany septicemic E. coli strains produce polysaccharide capsules, which are important for survival in serum. Here we show that a septicemic E. coli strain of serotype O78 produce an O-antigen capsule (group 4 capsule) and we show that this capsule is essential for serum survival.

Joshi, Debajyoti Bora, Debadatta Dhar (Chanda), Amitabha BhattacharjeeAbstractA wide range of intrinsic Acinetobacter-derived cephalosporinases (ADC) along with other carbapenemases has now been detected in Acinetobacter baumannii leaving clinicians with few treatment options. The present study reports the spread of ADC-30 co-producing KPC-2 along with other β-lactamases among carbapenem resistant A. baumannii st...
