Abstract

We attempted to prepare an agar plate containing Al under the acid conditions (pH 3.0) to count the number of colonies of Al-resistant microorganisms and isolate them. As a result, Al-resistant microorganisms were isolated from the tea garden soils and identified. 1) Agar could be solidified when the culture medium solution (pH 3.0), Al-2(SO4)(3) solution (pH 3.0), and agar solution were mixed after autoclaving separately. 2) The number of Al-resistant microorganisms was largest in the strong acid tea garden soil, followed by the forest soil and smallest in the upland soil. In particular, the number of Al-resistant microorganisms (Al 100 mM in agar medium) accounted for 12.5% of the number of total microorganisms, suggesting that the accumulation of Al-resistant microorganisms increased when the soil pH decreased. 3) Fungi accounted for most of the high Al-resistant microorganisms. 4) About half of the acid-tolerant fungi (grown at pH 3.0) from the tea garden soilsconsisted of high Al-resistant microorganisms (Al; 100 mM). 5) Fight strains Emericellopsis sp., Paecilomyces lilacinus, Moritierella ramanniana var, angulispora, Sprothrix inflata, Penicillium glabrum, Metarhizum anisopliae, Chaetospharia inaeqalis, and Aspergillus fumiatus were identified as Al-resistant fungi from the tea garden soils.
