Seasonal changes in the biochemical fate of carbon fixed by benthic diatoms in intertidal sediments [PDF]

open access: yes, 2018
Benthic diatoms are important primary producers in intertidal marine sediments and form the basis of the food web in these ecosystems. In order to investigate the carbon flow within diatom mats, we performed in situ 13C pulse-chase labeling experiments ...

The relationship between epilithic biofilm stability and its associated meiofauna under two patterns of flood disturbance [PDF]

open access: yes, 2012
Habitat stability is an important driver of ecological community composition and development. River epilithic biofilms are particularly unstable habitats for the establishment of benthic communities because they are regularly disturbed by floods. Our aim

Microbial Pigments-A Short Review

open access: yesIOSR Journal of Environmental Science, Toxicology and Food Technology, 2016
Color is the main feature of any food item as it enhances the appeal and acceptability of food. In the recent years, coloring of food with pigments produced from natural sources is of worldwide interest and is gaining importance. Several types of dyes are available in the market as colouring agents to food commodities but biocolorants are now gaining ...

Fungal Pigments: Their Diversity, Chemistry, Food and Non-Food Applications

open access: yesApplied Microbiology, 2023
Colorants have many applications in food, cosmetics, pharmaceutics, textile, paints, plastics, paper, ink and photographic industries. Colorants are classified according to their solubility into dyes and pigments.

Phytohormone-mediated interkingdom signaling shapes the outcome of rice-Xanthomonas oryzae pv. oryzae interactions [PDF]

open access: yes, 2015
Background: Small-molecule hormones are well known to play key roles in the plant immune signaling network that is activated upon pathogen perception. In contrast, little is known about whether phytohormones also directly influence microbial virulence ...

Picocyanobacteria and deep-ocean fluorescent dissolved organic matter share similar optical properties [PDF]

open access: yes, 2017
Marine chromophoric dissolved organic matter (CDOM) and its related fluorescent components (FDOM), which are widely distributed but highly photobleached in the surface ocean, are critical in regulating light attenuation in the ocean. However, the origins

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures

open access: yes, 2018
We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.

Spectral signatures of photosynthesis I: Review of Earth organisms

open access: yes, 2007
Why do plants reflect in the green and have a 'red edge' in the red, and should extrasolar photosynthesis be the same? We provide: 1) a brief review of how photosynthesis works; 2) an overview of the diversity of photosynthetic organisms, their light ...
