Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica
(2020)
In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ...
Concomitant prediction of environmental fate and toxicity of chemical compounds
(2020)
The environmental fate of many functional molecules that are produced on a large scale as precursors or as additives to specialty goods (plastics, fibers, construction materials, etc.), let alone those synthesized by the ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...
Streptomyces sp. M54: an actinobacteria associated with a neotropical social wasp with high potential for antibiotic production
(2021-01-17)
Abstract Streptomyces symbionts in insects have shown to be a valuable source of new antibiotics. Here,
we report the genome sequence and the potential for antibiotic production of ‘‘Streptomyces sp. M54’’, an Actinobacteria ...
Field performance of hermaphrodite papaya plants obtained through molecular selection and micropropagation
(2019)
Most commercial papaya varieties segregate hermaphrodite and female plants. Growers normally select hermaphrodite plants in the field, due to market preferences. This requires planting multiple plants per site and later ...
ArsH protects Pseudomonas putida from oxidative damage caused by exposure to arsenic
(2020-03-23)
The two As resistance arsRBC operons of Pseudomonas putida KT2440 are followed by a downstream gene called arsH that encodes an NADPH‐dependent flavin mononucleotide reductase. In this work, we show that the arsH1 and (to ...
Microbial Community Structure Alogn a Horizontal Oxygen Gradient in a Costa Rican Volcanic Influeced Acid Rock Drainage System
(2020-06-22)
We describe the geochemistry and microbial diversity of a pristine environment that resembles an acid rock drainage (ARD) but it is actually the result of hydrothermal and volcanic influences. We designate this environment, ...
Bocaparvovirus, Erythroparvovirus and Tetraparvovirus in New World Primates from Central America
(2020)
Parvoviruses in the genera Bocaparvovirus (HBoV), Erythroparvovirus (B19) and Tetraparvovirus (PARV4) are the only autonomous parvoviruses known to be associated with human and non‐human primates based on studies and ...
Temperature and elemental sulfur shape microbial communities in two extremely acidic aquatic volcanic environments
(2021)
Aquatic environments of volcanic origin provide an exceptional opportunity to study the adaptations of microbial communities to early planet life conditions such as high temperatures, high metal concentrations, and low pH. ...
The putative phosphate transporter PitB (PP1373) is involved in tellurite uptake in Pseudomonas putida KT2440
(2020)
Tellurium oxyanions are chemical species of great toxicity and their presence in the environment has increased because of mining industries and photovoltaic and electronic waste. Recovery strategies for this metalloid that ...
