Alkaline Catalase Produced by Bacillus No. Ku-1

The Basis of the Alkalophilic Property of a Species of Bacillus

“…Many cultures of alkalophilic bacteria related to the genus Bacillus have recently been isolated, and avariety of exoenzymes has been purified from the bacteria (Horikoshi, 1971(Horikoshi, a, b, 1972Horikoshi & Atsukawa, 1973a, b ;Kurono & Horikoshi, 1973;Boyer & Ingle, 1972). Since the bacteria are grown in alkaline culture media (pH 10 to II), it is not surprising that the exoenzymes obtained from the cultures exhibit alkalophilic and alkalostable properties.…”

“…Recently, many species of alkalophilic bacteria belonging to the genus Bacillus have been isolated (Horikoshi, 1971(Horikoshi, a, b, 1972Boyer & Ingle, 1972;Horikoshi & Atsukawa, 1973a, b ;Kurono & Horikoshi, 1973). These bacteria were found to prefer alkaline environments (PH 10 to I I) for their optimum growth.…”

Characterization and Some Cultural Conditions of a Cyclodextrin Glycosyltransferase-producing AlkalophilicBacillussp.

“…The bacterium, however, could utilized inorganic nitrogen compounds sUQh as (NH4)2S04, NH 4 Cl, NH 4 N0 3 , (NH 4 )2 HP0 4, CH 3 COONH 4 , ammonium citrate and urea, the CGTase was not appeared in the medium by these nutrients. Among of the organic nitrogen sources tested, the conbination of …”

Identification and Growth Characteristics of AlkalophilicCorynebacteriumsp. Which Produces NAD(P)-Dependent Maltose Dehydrogenase and Glucose Dehydrogenase

“…were essential for the growth. But inorganic nitrogen sources such as NH4N03, NH4Cl, NaN0 3 , KN0 3 , NH4HzP04 and (NH4)zHP0 4 were not effective. The optimal concentraion of soya-bean Fig.…”
