Distribution of unusual polyamines in aquatic plants and gramineous seeds

We tested several plants for the occurrence of unusual polyamines such as homospermidine, aminopropylhomospermidine, norspermidine, norspermine, thermospermine, and caldopentamine. The leaf and root of aquatic plants ubiquitously contained homospermidine in addition to usual polyamines such as putrescine, spermidine, spermine, and cadaverine. Homospermidine was widely distributed in the seed, seedling, leaf, and root of gramineous plants such as rice, millet, oat, rye, wheat, barley, corn, sorghum, and timothy as a minor polyamine. Aminopropylhomospermidine was found in the two aquatic plants, the water lily Nymphaca tetragona and the lotus Nelumbo nucifera as a major polyamine, and in the gramineous seeds as a minor polyamine. Norspermidine, norspermine, homospermine, and caldopentamine were detected in two floating aquatic plants, the duckweed Spirodela polyrhiza and the water hyacinth Eichhornia crassipes. Thermospermine was sporadically detected in some aquatic plants and gramineous seeds. Key words: Gramineae, aquatic plant, polyamine, homospermidine, caldopentamine.

Purification Efficiency

The effluent from activated sludge treatment of petroleum wastewater was treated with the aid of a ponding system using aquatic plants (Water Hyacinth, Chlorella, Reed). A good result was obtained in this study. Pilot pond system shows that the purification efficiency depends on the residence time of about 14 days. The petroleum removal waa 97-98 %, the COD removal was from 88-93 %. The dissolved oxygen amount (with Chlorella) increased from 0.7 mg/l to 9.8 mg/l and the pH increased from 6.9 to 8-8.6. The application of 3 step biological pond with the use of Water Hyacinth, Chlorella, Reeds for post treatment of petroleum wastewater is appropriate in Vietnam.

Biomass Resources

Lignocellulosic biomass resources are renewable materials that can be converted to fermentable sugars and subsequently into ethanol. Water hyacinth (Eichhornia crassipes) is a cellulosic aquatic plant that has high carbohydrates, low lignin content, and notable reducing sugars content in its structure. Based on the literature review in the case of water hyacinth, the most frequently used pretreatment methods were acid and alkali, while ionic liquid and microwave-assisted methods were used rarely. The dominant sugars were glucose, xylose, galactose, arabinose, and mannose. Based on the findings, cellulase and S. cerevisiae were mostly used for enzymatic hydrolysis and fermentation of water hyacinth to ethanol, respectively. This review presents the recent studies in pretreatment, hydrolysis, and fermentation of water hyacinth biomass into ethanol.

Nelumbo Nucifera

Background: Microorganisms from understudied habitats have been shown to be an important source of novel bioactive compounds. Endophytes constitute an underexplored group of microorganisms, of which those from aquatic plants have been even less studied. Nelumbo nucifera (lotus) is an aquatic plant with medicinal properties. A screening program for endophytes from N. nucifera by our research group resulted in many microbial isolates, of which isolate L-003 was a promising candidate, exhibiting antimicrobial and antioxidant activities. Objectives: The major objectives were to characterize the endophyte L-003 for its antimicrobial and antioxidant properties, identify the constituent bioactive compounds by GC-MS and characterize their activities further using in silico software. Methods: L-003 was identified by PIBWin software. Antimicrobial activity of the aqueous and organic extracts of culture supernatant of L-003 was checked against a panel of bacteria and fungi. Since the ethyl acetate extract showed the best antimicrobial activity, it was further characterized by thin layer chromatography, an activity confirmed by bioautography and purified by column chromatography. Total antioxidant capacity was assayed by standard techniques. Partially purified metabolite fingerprints were identified by GC-MS analysis. Results: Based on morphological and biochemical analyses, isolate L-003 was identified as belonging to Streptococcus sp. All the organic solvent extracts showed antimicrobial activity. Ethyl acetate extract showed maximum antimicrobial activity against all selected targets and exhibited antioxidant activity too, though butanol and aqueous extracts showed higher antioxidant activity. Two compounds, Acetic acid,-hydroxy, methyl ester and Disulfide, dipropyl, were identified by GC-MS in the metabolite fingerprint. These compounds showed differences in observed and calculated retention indices and could, therefore, be novel. In silico activity, characterization confirmed the antimicrobial and antioxidant properties attributed to these compounds. Conclusion: This is the first study reporting metabolite fingerprinting, identification and characterization of bioactive compounds from an endophytic isolate of Nelumbo nucifera. We conclude that endophytes from aquatic plants could be prospective sources of bioactive compounds, in this case with antimicrobial and antioxidant activities.

Rice Paddy Fields

Abstract E. crassipes, a native of South America, is a major freshwater weed in most of the frost-free regions of the world and is generally regarded as the most troublesome aquatic plant (Holm et al., 1997). It has been widely planted as a water ornamental around the world because of its striking flowers. Wherever it has encountered suitable environmental conditions it has spread with phenomenal rapidity to form vast monotypic stands in lakes, rivers and rice paddy fields. Then it adversely affects human activities (fishing, water transport) and biodiversity. It is impossible to eradicate, and often only an integrated management strategy, inclusive of biological control, can provide a long-term solution to this pest.

Four aquatic plants were tested for the occurrence of unusual polyamines. The leaves of the aquatic plants tested ubiquitously contained homospermidine in addition to usual polyamines such as diaminopropane, putrescine, cadaverine, spermidine, spermine, and agmatine. Brasenia schreberi and Nuphar japonicum belonging to the family Nymphaeaceae contained aminopropylhomospermidine. Norspermidine and norspermine were detected in the blackweed Hydrilla verticillata belonging to Hydrocharitaceae. Thermospermine was detected in Brasenia schreberi. A novel tetraamine, N,N'-bis(3-aminopropyl)-1,2-ethanediamine (NH2(CH2)3NH(CH2)2NH(CH2)3NH2), was discovered in the aquatic plant Nuphar japonicum. This is the first report of the occurrence of N4-methylspermidine (NH2(CH2)3N(CH3)(CH2)4NH2) in the water chestnut Trapa natas belonging to the family Hydrocaryaceae.

Aiming to identify the populations of aquatic plants present in the Porto Primavera reservoir and evaluate the behavior of Hydrilla verticillata colonization of this water body a survey was carried out in 2007. The data was based on presence or absence, only were assessed the presence or absence of the species and the data were subjected to cluster analysis to establish differences in distribution and occurrence of populations. The community of aquatic plants showed 24 species distributed in 16 botanical families. Cyperaceae and Pontederiaceae were the most representative in terms of species richness. The submerged macrophyte Hydrilla verticillata showed the highest frequency of occurrence in the water body, showing a different behavior from the other populations of the water body. Species like Eichhornia crassipes, Eichhornia azurea, Typha dominguensis and Oxycaryum cubense also showed different behavior in relation to other populations within the community, forming large populations in lagoons and backwater areas.
