Abstract

A survey of Bacillus thuringiensis was conducted for 17 locations in Northern Jordan representing 12 different habitats. Eighty isolates were identified as B. thuringiensis in the majority of the tested samples. Results showed that soils contaminated with the slaughterhouses waste materials had the highest content of spore-forming bacteria [(4.05-2.2) 10(7) CFU/g)] and B. thuringiensis [(4.05-7.9) 10(7) CFU/g)] with a (5.5%-14.9%) and (5.2%-7.7%) of the total viable bacterial count, respectively. These bacteria were more abundant in soils contaminated with such animal by-products.

摘要

在约旦北部的17个地点开展了一项针对苏云金芽孢杆菌的调查，这些地点代表了12种不同的栖息地。在大多数测试样本中，有80株分离菌被鉴定为苏云金芽孢杆菌。结果表明，被屠宰场废料污染的土壤中，形成芽孢的细菌含量最高[（4.05 - 2.2）×10⁷CFU/g]，苏云金芽孢杆菌含量也最高[（4.05 - 7.9）×10⁷CFU/g]，分别占总活菌数的（5.5% - 14.9%）和（5.2% - 7.7%）。这些细菌在被此类动物副产品污染的土壤中更为丰富。
