Fluid Imaging - Particle analysis in a fluid stream
FlowCAM is an instrument for rapid monitoring of particles in fluid. It combines the capabilities of flow cytometry and microscopy—providing an order of magnitude improvement over each. * FlowCAM automatically counts, images, and analyzes the cells in a discrete sample or a continuous flow, providing significantly increased data collection, instantly. * Its processing system captures a digital image of each cell and presents the data... - Read More

Algae processing simplified because of lack of lignocellulose?
"Processing is simplified because of microalgae’s small grain size and lack of lignocellulose; found in all land-based biomass sources, lignocellulose greatly complicates the biomass-to-biofuel conversion process" - so says HR Biopetroleum - Read More

New Biomass Extraction Equipment Increases Yields for Contract R&D, Toll Processing
A new biomass extraction processing line being assembled at POS Pilot Plant will maximize the amount of oil extracted from biomass, yield profitable by-products, and recycle the solvent used during processing. Depending on biomass composition, extraction capacity will approach 2 tonnes of dried biomass per day - making the technology ideal for contract R&D at the pilot plant scale, as well as for small scale specialty toll processing. - Read More

CO2 fixation and oil production through microalga
Microalgal oil production with secondarily treated sewage (STS) and thermochemical oil recovery from algal cells were studied. Botryococcus braunii produced hydrocarbons and consumed nitrate and phosphate in STS. Removal effects of the alga regarding As, Cd and Cr were observed during these experiments with an artificial medium. As for oil recovery from algal cells, the maximum yield of cil obtained by liquefaction was 64 wt% on a dry basis at 300°C with sodium carbonate catalyst (1995) - Read More

Olefins of High Molecular Weight in Two Microscopic Algae
The hydrocarbon composition of two algae, a golden-brown (Botryococcus braunii) and a blue-green (Anacystis montana), has been investigated by gas chromatography-mass spectrometry. Both show distributions of aliphatic hydrocarbons of odd carbon numbers in medium and high ranges of molecular weight, with maxima at n-C17 and n-C29 for B. braunii and n-C17 and n-C29 for A. montana. With the exception of the n-heptadecane of A. montana all the hydrocarbons are monoenes, dienes, or trienes (1968) - Read More

Analysis of energy conversion characteristics in direct liquefaction of algae
This study applies a thermochemical liquefaction process to convert biomass of algae into oil in the presence of water at high temperature (about 300–340 °C) and high pressure (about 20 MPa), with or w/o alkali catalyst. Thermochemical liquefaction has merit of not requiring drying process. The maximum oil and energy yields obtained at 33 & 40% on organic basis. Following conditions suggested: reaction temperature 340 °C, holding time 30 min, and catalyst dosage 5 wt.%. (2003) - Read More

Prevention of experimental oral cancer by extracts of Spirulina-Dunaliella algae
An extract of Spirulina-Dunaliella algae was shown to prevent tumor development in hamster buccal pouch when a 0.1% solution of 7,12-dimethylbenz[a]anthracene (DMBA) in mineral oil was applied topically three times weekly for 28 weeks. - Read More

Origin of Messel Oil Shale kerogen
(Dec 1988)..presence of cell-wall remains of Tetraedron-like microalgae virtually indistinguishable from those of the widely occurring extant Tetraedron minimum (Chlorococcales). Flash-pyrolysis gas chromatography/mass spectroscopy indicated presence of highly aliphatic biopolymer in both fossil & extant Tetraedron species. The bulk of Messel Oil Shale kerogen probably consists of preserved cell-wall material of Tetraedron algae, made up of this newly discovered biopolymer - Read More

Process for producing a naturally-derived carotene/oil composition by direct extraction from algae
A process for formation of a naturally derived composition comprising carotenes, particularly beta-carotene, in oil. It involves direct oil extraction of the carotene from algae. Algae are initially harvested as a water slurry and concentrated, as by flocculation, in the slurry. The concentrated part of the slurry is then mixed with oil and homogenized to form an oil emulsion. The water/oil emulsion is broken & the oil phase containing the carotene separated by centrifugation (patent 1987). - Read More
