Studies on the bacterial flora of Nasser's lake: the distribution of mesophilic species of genus bacillus in the lake water

ABSTRACT

An attempt has been made to study the bacterial ford of Nasser's lake. Water samples were collected from lake water along about .150 km at various depths and localities. Stress was made on the species composition of mesophilic bacteria of genus Bacillus, developed on nutrient agar and nutrient agar double strength. Identification studies have revealed that the mesophilic species of genus Bacillus were .c represented by 48 isolates, 5 belonged to Bacillus firmous; 5 to B. licheniformis; 9 to B. circulans; 4 to B. pumils; 6 to 3, brevis; 14 to B. subtilis; 4 to B. megaterium and 1 to B. alvei
