Bioprospecting for novel microalgal strains is key to improving the feasibility of microalgae-derived biodiesel production. Tetraselmis sp. CTP4 (Chlorophyta, Chlorodendrophyceae) was isolated using fluorescence activated cell sorting (FACS) in order to screen novel lipid-rich microalgae. CTP4 is a robust, euryhaline strain able to grow in seawater growth medium as well as in non-sterile urban ...

The Vibrio spp. are the most common and harmful shrimp pathogenic bacteria causing serious diseases of larval and postlarval stages in the hatchery. The Vibrio inhibitory activity of green algae Tetraselmis suecica has been reported in vitro (Austin and Day 1990).In these experiments, the inhibitory activity was assessed in vivo in a commercial shrimp hatchery of the white prawn Fenneropenaeus ...

Channelrhodopsins, such as the algal phototaxis receptor Platymonas subcordiformis channelrhodopsin-2 (PsChR2), are light-gated cation channels used as optogenetic tools for photocontrol of membrane potential in living cells. Channelrhodopsin (ChR)-mediated photocurrent responses are complex and poorly understood, exhibiting alterations in peak current amplitude, extents and kinetics of inactiv...

We present the description in central charge superspace of N = 4 supergravity with antisymmetric tensor coupled to an arbitrary number of abelian vector multiplets. All the gauge vectors of the coupled system are treated on the same footing as gauge fields corresponding to translations along additional bosonic coordinates. It is the geometry of the antisymmetric tensor which singles out which c...

Bacteria are remarkably associated with the growth of green algae Tetraselmis which used as a feed source in aquaculture, but Tetraselmis-associated bacterial community is characterized insufficiently. Here, first step towards characterization bacteria, we investigated composition free-living (FLB) and particle-associated (PAB) bacteria each phase (lag, exponential, stationary, death) suecica P...

The present work reports the use of living cells of the marine microalga Tetraselmis suecica for the biosorption of cadmium ions. For a better understanding of the biosorption characteristics, three fractions of removed cadmium (total, bioadsorbed and intracellular) were measured in the cells after 24 and 72 h of exposure to different initial cadmium concentrations (0.6-45 mg L(-1)). Both the L...

The primary requirements for high-biomass-concentration microalgal cultivation include a photon source and distribution, efficient gas exchange and suitable growth medium composition. However, for mass outdoor production of microalgae, growth medium composition is a major controlling factor as most of the other factors such as light source and distribution are virtually uncontrollable. This wor...
