The genus Haligena (Halosphaeriales, Ascomycota), with two accepted species, is encountered frequently in marine habitats, especially on wood in temperate regions. Phylogenetic analyses of Haligena elaterophora (type species) and H. salina were undertaken, with partial large subunit ribosomal DNA sequences, to determine their relationships with other closely related genera in the order. The gen...
BACKGROUND Dunaliella salina is the most important species of the genus for beta-carotene production. Several investigations have demonstrated that D. salina produces more than 10% dry weight of pigment and that the species grows in salt saturated lagoons. High plasticity in the green stage and the almost indistinguishable differences in the red phase make identification and differentiation of ...
A moderately halophilic, Gram-negative bacterium, designated strain BH843(T), was isolated from a solar saltern in Korea and subjected to a taxonomic analysis. Strain BH843(T) grew at salinities of 1-14 % (w/v) NaCl and at temperatures of 10-40 degrees C. The cells were motile cocci or short rods with single flagella and contained C(16 : 0), C(19 : 0) cyclo omega8c and C(17 : 0) cyclo as the ma...
Halomonas zhanjiangensis Chen et al. 2009 is a member of the genus Halomonas, family Halomonadaceae, class Gammaproteobacteria. Representatives of the genus Halomonas are a group of halophilic bacteria often isolated from salty environments. The type strain H. zhanjiangensis JSM 078169(T) was isolated from a sea urchin (Hemicentrotus pulcherrimus) collected from the South China Sea. The genome ...
results the dna-dna hybridization experiments between isolate tbz3, h. denitrificans and h. saccharevitans revealed relatedness levels of 57% and 65%, respectively. according to gc-ms results, tbz3 degrades paa to benzene, hexyl butanoate, 3-methyl-1-heptanol and hexyl hexanoate. temperature 32.92°c, ph 6.76, and salinity 14% are the optimum conditions for biodegradation with a confidence level...
Bloom of Dunaliella salina was observed naturally in stagnant puddles of water off Kuwait's Bubiyan Island on 4 July 2004. In order to closely monitor this bloom, alga were collected and maintained as pure culture of the locally isolated D. salina. Set of experiments was conducted to study and evaluate the optimum culture conditions required for two samples of D. salina (one locally isolated an...
Dunaliella salina, halotorelant unicellular green algae, is the main natural source of beta-carotene. Several strains of local Dunaliella salina were isolated. Together with Dunaliella bardawil DCCBC 15 and Dunaliella salina CCAP 19/18, the strains were examined for their growth under the effects of salinities (1 M, 1.5 M and 2 M) and light intensities (50, 100 and 150 μmol photon/m/s). The res...
Cactodera salina n. sp. (Heteroderinae) is described from roots of the estuary plant Salicornia bigelovii (Chenopodiaceae), in Puerto Pefiasco, Sonora, Mexico, at the northern tip of the Sea of Cortez. The halophyte host is grown experimentally for oilseed in plots flooded daily with seawater. Infected plants appear to be adversely affected by C. salina relative to plants in noninfested plots. ...
Light could induce phosphorylation of light harvesting chlorophyll a/b binding proteins (LHCII) in Dunaliella salina and spinach thylakoid membranes. We found that neither phosphorylation was affected by glycerol, whereas treatment with NaCl significantly enhanced light-induced LHCII phosphorylation in D. salina thylakoid membranes and inhibited that in spinach. Furthermore, even in the absence...
D. salina is one of the recognized natural sources to produce beta-carotene, and an useful model for studying the role of inhibitors and enhancers of carotenogenesis. However there is little information in D. salina regarding whether the isoprenoid substrate can be influenced by stress factors (carotenogenic) or selective inhibitors which in turn may further contribute to elucidate the early st...
