Inhibiting Methanogenesis Stimulated de novo Synthesis of Microbial Amino Acids in Mixed Rumen Batch Cultures Growing on Starch but Not on Cellulose.

Emilio M Ungerfeld et al.

Microorganisms, 8(6) (2020-05-30)

Ameliorating methane (CH4) emissions from ruminants would have environmental benefits, but it is necessary to redirect metabolic hydrogen ([H]) toward useful sinks to also benefit animal productivity. We hypothesized that inhibiting rumen methanogenesis would increase de novo synthesis of microbial

Inhibiting Methanogenesis in Rumen Batch Cultures Did Not Increase the Recovery of Metabolic Hydrogen in Microbial Amino Acids.

Emilio M Ungerfeld et al.

Microorganisms, 7(5) (2019-05-01)

There is an interest in controlling rumen methanogenesis as an opportunity to both decrease the emissions of greenhouse gases and improve the energy efficiency of rumen fermentation. However, the effects of inhibiting rumen methanogenesis on fermentation are incompletely understood even

The mitosis-to-interphase transition is coordinated by cross talk between the SIN and MOR pathways in Schizosaccharomyces pombe.

Samriddha Ray et al.

The Journal of cell biology, 190(5), 793-805 (2010-09-02)

The mechanisms that regulate cytoskeletal remodeling during the transition between mitosis and interphase are poorly understood. In fission yeast the MOR pathway promotes actin polarization to cell tips in interphase, whereas the SIN signaling pathway drives actomyosin ring assembly and

Biological Carbon Recovery from Sugar Refinery Washing Water into Microalgal DHA: Medium Optimization and Stress Induction.

Myounghoon Moon et al.

Scientific reports, 9(1), 19959-19959 (2019-12-29)

Sugar refinery washing water (SRWW) contains abundant levels of carbon sources and lower levels of contaminants than other types of wastewater, which makes it ideal for heterotrophic cultivation of microalgae. Here, carbon sources in SRWW were utilized for conversion into

Systemic muscle wasting and coordinated tumour response drive tumourigenesis.

Holly Newton et al.

Nature communications, 11(1), 4653-4653 (2020-09-18)

Cancer cells demand excess nutrients to support their proliferation, but how tumours exploit extracellular amino acids during systemic metabolic perturbations remain incompletely understood. Here, we use a Drosophila model of high-sugar diet (HSD)-enhanced tumourigenesis to uncover a systemic host-tumour metabolic

Measuring Streptococcus mutans, Streptococcus sanguinis and Candida albicans biofilm formation using a real-time impedance-based system.

Pedro M D S Abrantes et al.

Journal of microbiological methods, 169, 105815-105815 (2019-12-25)

Candida albicans and streptococci are amongst the most common fungal and bacterial organisms present in the oral cavity, with a growing body of evidence implicating C. albicans in increased caries severity and in the formation of the cariogenic biofilm. However

LsrR quorum sensing "switch" is revealed by a bottom-up approach.

Sara Hooshangi et al.

PLoS computational biology, 7(9), e1002172-e1002172 (2011-10-08)

Quorum sensing (QS) enables bacterial multicellularity and selective advantage for communicating populations. While genetic "switching" phenomena are a common feature, their mechanistic underpinnings have remained elusive. The interplay between circuit components and their regulation are intertwined and embedded. Observable phenotypes

Frontline Science: Microbiota reconstitution restores intestinal integrity after cisplatin therapy.

Alfredo Perales-Puchalt et al.

Journal of leukocyte biology, 103(5), 799-805 (2018-03-15)

Due to their cytotoxic activities, many anticancer drugs cause extensive damage to the intestinal mucosa and have antibiotic activities. Here, we show that cisplatin induces significant changes in the repertoire of intestinal commensal bacteria that exacerbate mucosal damage. Restoration of

Hypoxia modifies the feeding preferences of Drosophila. Consequences for diet dependent hypoxic survival.

Paul Vigne et al.

BMC physiology, 10, 8-8 (2010-05-15)

Recent attention has been given to the relationships between diet, longevity, aging and resistance to various forms of stress. Flies do not simply ingest calories. They sense different concentrations of carbohydrate and protein macronutrients and they modify their feeding behavior
