Bacillus licheniformis SPT 27 is an isolate which produces extra cellular alpha (α-) amylase exhibiting activity at a wide pH range and was relatively stable. The B. lichenformis isolate, however, produces low yields of the amylase. Our results show that the amylase production is higher in the presence of starch, with Amarantus peniculatus starch producing the highest amount of amylase. Amongst sugars, fructose supported maximum amylase production. Of the nitrogen sources tested, peptone and ammonium hydrogen phosphate where the best organic and inorganic sources respectively. The C:N ratio found to be the optimum was 1:1. Key Words: Amarantus manipulates , alpha (α-) amylase, Bacillus licheniformis SPT 27, C:N ratio. African Journal of Biotechnology Vol.3(10) 2004:519-522

- Amylase production by Penicillium fellutanum isolated from mangrove rhizosphere soil (2006, background): “In the present study the amylase activity increased steadily and reached maximum at 96 h of incubation (Table 3), as against a short duration of 24 h in the case of bacteria (Dharani Aiyer, 2004).”
- Amylase activity of a starch degrading bacteria isolated from soil receiving kitchen wastes (2008, result): “This result is different from some of the recent observation in some Bacillus species (Aiyer, 2004), where increase in incubation time decrease enzyme activity.”
