Summary A total of 107 bacterial strains were isolated from rhizosphere soil of Diplachne fusca naturally grown in industrial metal-contaminated soils. All the isolates were examined for their ability to tolerate Cd2+, Cr3+, Co2+, Cu2+, Pb2+, Ni2+ and Zn2+ in their growth medium, in addition, three related phenotypic characters, the ability to produce acids and siderophores and/or
calcium phosphate solubilization, were tested. The resistance patterns, expressed as MICs, for all bacterial isolates to seven
different metal ions were surveyed by using the agar dilution method. A great proportion of the isolates were resistant to
Cr (99%), Pb (93%), Cu (87%) and Zn (86%). On the other hand, 77, 49 and 45% were sensitive to Co, Ni and Cd, respectively.
The majority of the strains tested (98%) were multiple metal-resistant, with hexametal resistance as the major pattern (24.2%).
The increase in metal ion uptake (especially Cr, Pb, Zn and Ni) by D. fusca was correlated with higher numbers of siderophore-producing, phosphate-solubilizing and acid-producing bacteria 95, 81 and
64%, respectively. 相似文献

Summary In a continuous flow of domestic sewage, the effect of various environmental conditions on the oxygen balance of an algal-bacterial culture was studied in 2 microponds in series. The relation between the size of the algal population and the amount of photosynthetic oxygen was discussed.The efficiency of the symbiotic system in relation to photosynthetic oxygenation was elucidated in terms of two oxygenation factors. One is concerned with the consumption of oxygen by the existing flora and the other with the BOD of the influent substrate.Prof. of Botany, Fac. of Science.Lecturer in Sanitary Biol., Fac. of Engineering. 相似文献
