Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

open access: yesThe FEBS Journal, EarlyView.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Distribution and activity of nitrate and nitrite reductases in the microbiota of the human intestinal tract

open access: yesThe FEBS Journal, EarlyView.
Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

Dental Factors Associated With Oropharyngeal Dysphagia in Institutionalised Older Adults: A Systematic Review

open access: yesGerodontology, EarlyView.
ABSTRACT Background Aging is associated with a decline in physiological functions. Dysphagia, a disorder among older adults, impairs feeding and is related to morphological and functional changes in the stomatognathic system, which worsen with age‐related physiological decline, particularly among institutionalised older adults.

Prediction of organic acid concentration in BRS Capiaçu elephant grass silage

open access: yesGrassland Science, EarlyView.
Abstract This study aimed to develop prediction models for organic acid concentrations in Capiaçu grass (Pennisetum purpureum Schum) silage, based on fermentation parameters and chemical composition. Data were obtained from an experiment that evaluated BRS (Brazil Seeds) Capiaçu grass silage with the inclusion of dehydrated cashew pseudofruit ...
