The name game: morpho-molecular species boundaries in the genus Psammocora (Cnidaria, Scleractinia)
Provedor de dados: 5
Autores: Benzoni, Francesca; Stefani, Fabrizio; Pichon, Michel; Galli, Paolo.
The morphometric and molecular boundaries between twelve Psammocora (Cnidaria, Scleractinia) nominal species were addressed. The type specimens of Psammocora haimiana Milne Edwards &amp; Haime, 1851, P. togianensis Umbgrove, 1940, P. folium Umbgrove, 1939, P. digitata Milne Edwards &amp; Haime, 1851, Maeandroseris australiae Rousseau, 1854, P. samoensis Hoffmeister, 1925, P. superficialis Gardiner, 1898, P. profundacella Gardiner, 1898, P. nierstraszi Van der Horst, 1921, P. verrilli Vaughan, 1907, and P. albopicta Benzoni, 2006, were analysed together with specimens from museum collections, including those depicted in widely cited taxonomic descriptions, and material collected for this study in different parts of the Indo-Pacific. Morphometric analyses of...

High biodegradation levels of 4,5,6-trichloroguaiacol by Bacillus sp. isolated from cellulose pulp mill effluent
Provedor de dados: 59
Autores: Tondo,E.C.; Andretta,C.W.S.; Souza,C.F.V.; Monteiro,A.L.; Henriques,J.A.P.; Ayub,M.A.Z.
An aerobic Gram positive spore-forming bacterium was isolated from cellulose pulp mill effluent. This microorganism, identified as Bacillus sp. and named IS13, was able to rapidly degrade the organic chlorinated compound 4,5,6-trichloroguaiacol (4,5,6-TCG) from a culture containing 50 mg/l, which corresponds to about 3x104 times the concentration found in the original effluent. The biodegradation of this compound, usually found in cellulose pulp mill effluents, was evaluated by spectrophotometry and gas chromatography analysis. During 4,5,6-TCG decreasing, the lack of by-products had shown by such analysis lead to verify the possibility of either adsorption or absorption of 4,5,6-TCG by the cells, instead of real biodegradation. There were no traces of...

Comparative study on the biodegradation of chlorpyrifos-methyl by Bacillus megaterium CM-Z19 and Pseudomonas syringae CM-Z6
Provedor de dados: 42
Autores: ZHU,JIANGWEI; ZHAO,YAN; RUAN,HONGHUA.
Abstract: The strains CM-Z19 and CM-Z6, which are capable of highly degrading chlorpyrifos-methyl, were isolated from soil. They were identified as Bacillus megaterium CM-Z19 and Pseudomonas syringae CM-Z6, respectively, based on the 16S rRNA and an analysis of their morphological, physiological and biochemical characteristics. The strain CM-Z19 showed 92.6% degradation of chlorpyrifos-methyl (100 mg/L) within 5 days of incubation, and the strain CM-Z6 was 99.1% under the same conditions. In addition, the degradation characteristics of the two strains were compared and studied, and the results showed that the strain CM-Z19 had higher phosphoesterase activity and ability to degrade the organophosphorus pesticide than did the strain CM-Z6. However, the...

3,5,6-trichloro-2-pyridinyloxyacetic acid as effective thinning agent for fruit of 'Montenegrina' mandarin
Provedor de dados: 65
Autores: Gonzatto,Mateus Pereira; Böettcher,Gerson Nestor; Schneider,Leonardo André; Lopes,Ângelo Azeredo; Silveira Júnior,Jairo Camargo; Petry,Henrique Belmonte; Oliveira,Roberto Pedroso de; Schwarz,Sergio Francisco.
ABSTRACT: The 'Montenegrina' mandarin ( Citrus deliciosa Tenore) is widely cultivated in southern Brazil. This cultivar has a great tendency for alternate bearing, requiring thining of the fruit. However, the chemical thinners studied until now in this cultivar have not been successful. The objective of this research was to evaluate the effect of 3,5,6-trichloro-2-pyridinyloxyacetic acid (3,5,6-TPA) on the production and fruit quality of the 'Montenegrina' mandarin, in comparison with hand thinning and the options of chemical thinning previously studied. Hand thinning and no thinning were used as controls. Ethephon was applied in three doses: 200mg L-1, 300mg L-1 or 200mg L-1 + 3% urea; or 3,5,6-TPA, in four doses: 10, 20, 30 or 40mg L-1. Fruits of the...
