Low hydrocarbon concentrations stimulated the growth of Tetraselmis suecica, whereas higher concentrations (200 ppm) inhibited growth. The content of chlorophyll a in this microalga was affected in a similar way. Crude oil had the most marked effects. Dispersant SEAKLIN-101-NT and mixtures of oil and SEAKLIN-101-NT did not show selective toxicity for the microalga, although inhibitory effects c...

Mixotrophic metabolism was evaluated as an option to augment the growth and lipid production of marine microalga Tetraselmis sp. FTC 209. In this study, a five-level three-factor central composite design (CCD) was implemented in order to enrich the W-30 algal growth medium. Response surface methodology (RSM) was employed to model the effect of three medium variables, that is, glucose (organic C...

Microalgae are an untapped source of bioactive compounds with various biotechnological applications. Several species industrially produced and commercialized for the feed or cosmetic industries, however, other applications in functional food pharmaceutical markets can be foreseen. In this study, nine industrial/commercial were evaluated vitro antioxidant, calcium-chelating, anti-tumoral, anti-i...

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 ...

Algae are a diverse group of aquatic organisms and have potential to produce renewable biofuel via hydrothermal liquefaction (HTL). This study investigated the effects reaction environments on biocrude production from “Tetraselmis sp.” algae strain by HTL process using red mud (RM) based catalyst. The inert (N2), ethylene (C2H4), reducing (10% H2/90% N2), oxidizing O2/90% N2) were applied non-c...

Abstract The marine bacterium Vibrio parahaemolyticus is the leading cause of seafood-related food poisoning worldwide and a pathogen species harvested in aquaculture. An outbreak pathogenic V. within crustacean bi-valve aquaculture facilities often results significant loss farmed product spread into human population. Evidence shows several bacteria microalgae have antibacterial effects against...

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...
