Human exploitation of marine ecosystems is more recent in oceanic than near shore regions, yet our understanding of human impacts on oceanic food webs is comparatively poor. Few records of species that live beyond the continental shelves date back more than 60 y, and the sheer size of oceanic regions makes their food webs difficult [...]

Two musical stimuli transmissions (Mozart and Romanza) as compared with white noise treatment or control, both resulted in significantly higher growth performance in juvenile (6.7 ± 0.12 g) rainbow trout (Oncorhynchus mykiss) reared for 14 weeks. Carcass chemical composition and fatty acid composition (% of total fatty acids and mg/g carcass wet weight) did not [...]

We believe that there should be someone at the DoE who is willing to be honest – to tell our elected officials that times have changed, and so have the needs. They are not willing to tell you, but I am. If the US does not do something quickly we will soon be buying our [...]

A variety of biofuel and biorefinery products have been produced from engineered Escherichia coli till date. Most of these products had been derived from simple sugars in its pure form, rather than deriving it from alternative, renewable and carbon neutral sources, such as marine alga biomass. Engineering E. coli to use algal hydrolysate can make [...]

Highlights• Chlorella species were mutated by 60Co γ irradiation for high CO2 tolerance.• Mutants were domesticated by high concentrations of CO2 for higher growth rate.• Biomass yield of domesticated mutants was 0.5 times higher than original strain.• Enhancing light transmission and culture mixing promoted algae growth rate.• The peak CO2 fixation efficiency of Chlorella PY-ZU1 [...]

The present study was aimed at determining the effects of ginger (Zingiber officinale Roscoe) as feed additive on Asian sea bass, Lates calcarifer culture. Experimental diets containing ginger 1, 2, 3, 5 and 10 g/kg of feed were fed to L. calcarifer and control was fed with no ginger. After the feeding trial for 15 [...]

This study aims to quantify water appropriation and the potential production of algal bio-oil using freshwater and municipal wastewater effluent (MWW) as an alternative water resource. The county-level analysis focuses on open-pond algae cultivation systems located in 17 states in the southern United States. Several scenarios were developed to examine the water availability for algae [...]

This paper investigates the effect of recycling on biomass energy yield in High Rate Algal Ponds (HRAPs). Two 8 m3 pilot-scale HRAPs treating primary settled sewage were operated in parallel and monitored over a 2-year period. Volatile suspended solids were measured from both HRAPs and their gravity settlers to determine biomass productivity and harvest efficiency. [...]

To combat this, Sandia developed a toolkit to address the RapTOR (Rapid Threat Organism Recognition) challenge — with a goal of 24 hour turnaround in characterizing new threats. . It was designed to serve as a tool to rapidly characterize a biological organism with no pre-existing knowledge.It’s this toolkit that has now been applied to [...]

Biofuel production from microalgal biomass could be an alternative solution to conventional biofuels typically dependent on food and high land/water demanding crops. However, the economic and energetic viability of microalgal biofuels is limited by their harvesting processes. The finding of innovative, low cost and efficient harvesting method(s) is imperative.In this study, the Electro-Coagulation (EC) was [...]
