Title

THE STUDY OF THE ECOPHYSIOLOGICAL EFFECTS OF SOIL CYANOBACTERIUM NOSTOC SP. AS SALINE SOIL CONDITIONER AND POTENTIAL OF GROWTH, VIABILITY AND AMMONIUM LIBERATION AT HIGH TEMPERATURE CONDITION

Pages

  79-88

Abstract

 Soil CYANOBACTERIA seems potent organisms considering pharmaceutical characteristics. Antifungal, antiviral and antibacterial abilities have been shown and recently two special substances with anticancer and HSVII abilities have been discovered in these organisms. Nostoc sp; may be considered from salt adjustment and viability at high temperatures point of view. Soil collection had been done during one year. Soil samples had been cultured and after isolation and identification of CYANOBACTERIA, this strain had been selected and cultured in BG-11 medium under 2 micromol quanta.m-2.s-1 white continuous illumination and 450C temperature. Salt treatment was 1% NaCl and had been done under limited carbon dioxide condition. Growth was evaluated using optical density (OD750). Pigments were extracted and assayed as methanolic extract. AMMONIUM LIBERATION was assayed on different days at 1% salt concentration conditions. Salinity and temperature stresses had been analyzed by pigment content flactuations. Results showed that this strain may be viable at 45oC. The highest rate of AMMONIUM LIBERATION was related to 1% salinity at second day. The highest rate of pigment content was related to carotenoide at invivo and chlorophyll (a) and carotenoide at invitro condition. The highest amount of chlorophyll had been shown in third day and carotenoides at the first day after inoculation. As a conclusion, these strain seemed viable in saline soils and temperate humid conditions.
