Extracting high-quality RNA from common grape hyacinth flowers using common methods is difficult because of high levels of polysaccharide in flowers. Total RNA was isolated from common grape hyacinth with modified CTAB method and SDS method. UV-Spectroscopic analysis showed that A(260)/A(280)= 1.8~2.0,28S,18SrRNA were all clear in electrophoresis picture.
With contrast experiments,the results indicate that after 8 h adsorption by the dry air cells of water hyacinth,the concentration of chlorine ion in the saponin wastewater reduce 10%,chroma reduce 97.2%,pH change from 1.09 to 1.26,COD removal efficiency is 20%.
Based on the analysis of the comparison of the water quality determination, this paper shows that under the average water temperature of 15 ℃ and average illuminate of 1 379 Lx, 1 kg water hyacinth absorbs PO43－- P 5. 0 mg/d and NO2 - N and NH4+ - N 47. 9 mg/d in average.
经过水质测定表明，当平均照度 1379Lx、平均水温15 ℃时，测得每公斤水葫芦可以从水体中吸收PO43－－P 5．0 mg／d，吸收NO2－N和NH4＋－ N 47． 9 mg／d；
After NaOH and enzymic degradation of hyacinth stem and leaf, the hydrogen production yield and peak rate were respectively 49.7mL/g and 0.48mL/(h·g), when pH value of fermentation solution was 6 and temperature was 35℃ .
Three forms of silver (Ag+, [Ag (S2O3)2]3-, AgBr) have been selected in the static experiment of purification of silver-bearing waste water from cinefilm processing factory by water hyacinth. The results indication that silver removal rates from SBWW within 24 hours were 0. 136, 0. 054 and 0. 030 for Ag+, [Ag (S2O3)2]3- and AgBr respectively.
Cu 0.57to 0.32 ppb, Pb 0.14 to 0.06 ppb, Zn 65.6 to 23.6 ppb and Cd 0.14 to 0.03 ppb, ect. Meamwhile it improved water greatly, increasing the water transparency from 36.7 to90cm. Therefore, the river water after treated by water hyacinth could reach thestandard water quality suitable for fishes.
The three fluorescence lifetimes are 30, 274 and 805 ps for the pseudo ginseng chloroplast; 138, 521 and 1494 ps for the water hyacinth chloroplast; 197, 465 and 1459 ps for the spinach chloroplast, respectively.
The excitation energy conversion efficiency(η) in PS II RC is defined and calculated on the basis of the 20 ps electron transfer time constant model, 60%, 87% and 91% for the pseudo ginseng, water hyacinth and spinach chloroplasts, respectively.
Our result in this work stands in line with the 20 ps electron transfer time constant in PS II rather sound and the water hyacinth plant grows slower than the spinach plant does as envisaged on the efficiency.
