Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

Angewandte Chemie, EarlyView.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult

Photosynthetic response of Chlamydomonas reinhardtii and Chlamydomonas sp. 1710 to zinc toxicity

Frontiers in Microbiology
Zinc (Zn) is an essential trace element but can lead to water contamination and ecological deterioration when present in excessive amounts. Therefore, investigating the photosynthetic response of microalgae to Zn stress is of great significance.

An exploratory study on the possibilities of microalgal biotechnology to obtain the essential 6Li isotope as fusion fuel

Biotechnology for Biofuels and Bioproducts, 2023
Future energy supply needs to overcome two challenges: environmental impact and dependence on geopolitically unstable countries. A very promising alternative is based on lithium, an element for batteries, and whose isotope 6Li will be essential in ...

Gamete dimorphism of the isogamous green alga (Chlamydomonas reinhardtii), is regulated by the mating type-determining gene, MID

Communications Biology, 2022
The mating type determining gene, MID, in Chlamydomonas reinhardtii algae governs formation of the α and β mating structures, highlighting a potential genetic basis for mating type- or sex-specific asymmetric positioning of the chlorophyte mating ...

Herbicide cycling has diverse effects on evolution of resistance in Chlamydomonas reinhardtii [PDF]

, 2012
Cycling pesticides has been proposed as a means of retarding the evolution of resistance, but its efficacy has rarely been empirically tested. We evolved populations of Chlamydomonas reinhardtii in the presence of three herbicides: atrazine, glyphosate ...

Eyespot-Assembly Mutants in Chlamydomonas reinhardtii [PDF]

Genetics, 1999
Abstract Chlamydomonas reinhardtii is a single-celled green alga that phototaxes toward light by means of a light-sensitive organelle, the eyespot. The eyespot is composed of photoreceptor and Ca++-channel signal transduction components in the plasma membrane of the cell and reflective carotenoid pigment layers in an underlying region of

Chemotactic responses of Chlamydomonas reinhardtii. [PDF]

Molecular and Cellular Biology, 1981
A capillary chemotaxis assay revealed that among a wide range of inorganic and organic chemicals, only ammonium ion (NH4+) could serve as an attractant of Chlamydomonas reinhardtii. NH4+ (10(-2) M) gave the maximum response, with up to a 15-fold increase in accumulated algae being measured. No repellents for the chlorophyte were detected.

Multi-Pixel Photon Counters for Optofluidic Characterization of Particles and Microalgae

Biosensors, 2015
We have developed an optofluidic biosensor to study microscale particles and different species of microalgae. The system is comprised of a microchannel with a set of chevron-shaped grooves. The chevrons allows for hydrodynamic focusing of the core stream

Uni-directional ciliary membrane protein trafficking by a cytoplasmic retrograde IFT motor and ciliary ectosome shedding [PDF]

, 2015
The role of the primary cilium in key signaling pathways depends on dynamic regulation of ciliary membrane protein composition, yet we know little about the motors or membrane events that regulate ciliary membrane protein trafficking in existing ...
