Identification of a Marine AgarolyticPseudoalteromonas Isolate and Characterization of Its Extracellular Agarase
TLDR
The phenotypic and agarolytic features of an unidentified marine bacteria that was isolated from the southern Pacific coast was investigated and this strain was identified as Pseudoalteromonas antarcticastrain N-1, gram negative, obligately aerobic, and polarly flagellated. Expand

  • 1 May 1995
TLDR
Combined 1H and 13C nuclear magnetic resonance spectroscopy represent the most effective and powerful method for the investigation of the chemical structure of agarocolloids. Expand
Agars from three species of Gracilaria (Rhodophyta) from Yucatán Peninsula.
TLDR
Alkali treatment was effective both in removing alkali-labile sulphate and increasing the gel strength in G. crassissima and G. blodgettii, and this species may be considered for exploitation as a source of commercial grade agar. Expand
Chemical and macromolecular characterisation of agar polymers from Gracilaria dura (C. Agardh) J. Agardh (Gracilariaceae, Rhodophyta)
Abstract Agar polymers were extracted with and without alkali pre-treatment from the red seaweed Gracilaria dura , growing in the northern Adriatic Sea. Chemical analysis combined with 1 H and 13 CExpand
The effect of light on growth and agar content of Gelidium pulchellum (Gelidiaceae, Rhodophyta) in culture
Investigation of light conditions suitable for cultivation of Gelidium pulchellum (Turner) Kurtz was performed under controlled laboratory conditions at 20 °C and in the range of irradiance of 10–430Expand
Structure and properties of agar from two unexploited agarophytes from Venezuela
TLDR
The red seaweeds Gelidiella acerosa and Gracilaria mammillaris growing along the coast of Venezuela were investigated as potential economic sources of agar and galactan exhibited quite good properties, comparable to that of commercial agaroses. Expand
Investigation of the carrageenans extracted from Solieria filiformis and Agardhiella subulata from Mar Piccolo, Taranto
Abstract Dried samples of the red algae Solieria filiformis and Agardhiella subulata from Mar Piccolo, Taranto, were extracted by stirring in water at 25 (Cold), 85 (Hot) and 120 (pressure) °C. ForExpand
Modified procedures for extraction and analysis of carrageenan applied to the red alga Hypnea musciformis
Dried powder of Hypnea musciformis was extracted with water at pH 7 after an initial short pre-treatment with cold, diluted HCl. Carrageenans were isolated by alcohol precipitation after an amylaseExpand
The effect of light on growth and agar content of Gelidium pulchellum (Gelidiaceae, Rhodophyta) in culture
TLDR
Investigation of light conditions suitable for cultivation of Gelidium pulchellum (Turner) Kurtz was performed under controlled laboratory conditions and in the range of irradiance of 10–430 μmol photons m−2 s−1 and the gel strength was considerably lower at high light intensity. Expand
