Аннотация: Biodegradation of film specimens from polyhydroxyalkanoates (PHAs) of two types - poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3- hydroxyvalerate (PHBV) - was analysed in different environments: tropical sea waters of the South China Sea (Nha Trang, Vietnam) and soils in the environs of Hanoi (Vietnam), Nha Trang (Vietnam) and Krasnoyarsk (Siberia, Russia). In seawater, the mass loss of the specimens of both types was almost equal. However, in tropical soils, PHB degraded quicker than PHBV. In the Siberian soil, the degradation rate of the PHBV was generally higher than that of PHBV. Analysis of molecular mass of PHA specimens showed its decreasing during biodegradation. In the tropical sea conditions, PHA degrading microorganisms were represented by bacteria of Enterobacter, Bacillus and Gracilibacillus genera. Among PHA degrading bacteria, Burkholderia, Alcaligenes, Bacillus, Mycobacterium and Streptomyces genera were identified in Vietnamese soils, and Variovorax, Stenotrophomonas, Acinetobacter, Pseudomonas, Bacillus and Xanthomonas genera in Siberian soils. Micromycetes of Gongronella, Paecilomyces, Penicillium and Trichoderma genera exhibited PHA degrading activity in Vietnamese soils, and Paecilomyces, Penicillium, Acremonium, Verticillium and Zygosporium genera - in Siberian soils.

Biodegradation of polyhydroxyalkanoates (PHAs) in tropical coastal waters and identification of PHA-degrading bacteria / T. G. Volova [et al.] // Polymer Degradation and Stability. - 2010. - Vol. 95, Is. 12. - P2350-2359, DOI 10.1016/j.polymdegradstab.2010.08.023 . - ISSN 0141-3910

Аннотация: Biodegradability patterns of two PHAs: a polymer of 3-hydroxybutyric acid (3-PHB) and a copolymer of 3-hydroxybutyric and 3-hydroxyvaleric acids (3-PHB/3-PHV) containing 11 mol% of hydroxyvalerate, were studied in the tropical marine environment, in the South China Sea (Nha Trang, Vietnam). No significant differences have been observed between degradation rates of 3-PHB and 3-PHB/3-PHV specimens; it has been found that under study conditions, biodegradation is rather influenced by the shape of the polymer item and the preparation technique than by the chemical composition of the polymer. Biodegradation rates of polymer films in seawater have been found to be higher than those of compacted pellets. As 3-PHB and 3-PHB/3-PHV are degraded and the specimens lose their mass, molecular weight of both polymers is decreased, i.e. polymer chains get destroyed. The polydispersity index of the PHAs grows significantly. However, the degree of crystallinity of both PHAs remains unchanged, i.e. the amorphous phase and the crystalline one are equally disintegrated. PHA-degrading microorganisms were isolated using the clear-zone technique, by inoculating the isolates onto mineral agar that contained PHA as sole carbon source. Based on the 16S rRNA analysis, the PHA-degrading strains were identified as Enterobacter sp. (four strains), Bacillus sp. and Gracilibacillus sp.В© 2010 Elsevier Ltd. All rights reserved.

Аннотация: Approximately 100 fish belonging to 24 families and several representatives of cephalopods, prawns, and euphausiids were investigated for the presence of luminescent bacteria. Species identification of isolated luminescent bacteria was performed, and the frequency and ratio of their occurrence in the gastrointestinal microflora of marine animals were determined. Luminescent bacteria occurred in 23 - 65% of the fish, depending on the habitat depth, and their ratio varied from 8 to 60% of the total gastrointestinal microflora of fish. The free-living luminescent bacteria were found in 50% of the seawater samples from depths down to 1000 m. The luminescent bacterium Photobacterium phosphoreum was dominant among the isolated cultures.
