 ที่มา:KASETSART UNIVERSITY FISHERIES RESEARCH BULLETINหัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Freshwater Phytoplankton in Thailand I: Euglenophyceae) ผู้เขียน:นางลัดดา วงศ์รัตน์, ศาสตราจารย์, นายประจิตร วงศ์รัตน์, อาจารย์, Suneerat Ruangsomboon สื่อสิ่งพิมพ์:pdf AbstractThis article is a part of a series of diversity study on freshwater phytoplankton of Thailand. The study based upon examinations of 248 plankton samples collected from various types of water bodies in the central and eastern parts of the country, during 1998 and 2003. A list of one hundred and six species, thirty-three varieties, and two forms of euglenoids is provided. Many of the taxa encountered are well known cosmopolitan forms. A further illustrated and brief taxonomic description of the first record taxa is also given. This includes fifty species, twenty-one varieties, and two forms. This study provides baseline data for future diversity and ecological studies of freshwater phytoplankton in Thailand. |
 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Lead (Pb2+) Removal from Wastewater by the Cyanobacterium Calothrix marchica) ผู้เขียน:Suneerat Ruangsomboon, Amnat Chidthaisong, Boosya Bunnag, Duangrat Inthorn, Narumon W. Harvey สื่อสิ่งพิมพ์:pdf AbstractPb2+ removal ability of the living-freshwater cyanobacterium C. marchica was studied in batch experiments. The result showed that adsorption of Pb2+ by C. marchica reached equilibrium within 60 min. The amount of Pb2+ adsorbed (qeq) increased when cyanobacterial age increased. At lower biomass concentration cyanobacterium showed higher qeq than that at high biomass concentration. Elevated temperature increased Pb2+ adsorbed by C. marchica. The Langmuir adsorption isotherm fitted the results better than the Freundlich isotherm and, thus, was more suitable to describe Pb2+ adsorption by C. marchica. C. marchica had Pb2+ binding capacity (qmax) of 74.04 mg g-1, and indicators of adsorption capacity (Kf) of 18.01. Pb2+ removal under light and dark conditions was not significantly different. |
