“…It had been reported that Bacillus sp. as the potent source of amylases (Roy et al, 2012;Najafi et al, 2005), however, in our results we got pathogenic Streptococcus sps. more potent amylase producer than the isolated Bacillus spps.…”

“…These results were in agreement with ElBanna et al, (2007) results who found that presence starch enhanced , α-amylase production by B. subtilis ; whereas other carbon tested have no effect on α-amylase synthesis. (Božić, et al, 2011& Roy et al ,2012 found α-amylase production by different bacterial strains were increased addition starch to medium .…”

Background: Starch-degrading amylase enzyme is important in biotechnological applications as food, fermentation, textile, paper and pharmaceutical purposes. The aim of current study to isolate alkaline thermostable α-amylase bacteria and then study the composition of medium and culture conditions to optimize cells growth and a-amylase production. Materials and Methods: Thermophilic amylase producing bacterium was isolated from local hot water-springs in Gazan city Saudi Arabia. Results: Phylogenetic analysis of 16 S rRNA sequence for the strain revealed that the strain have the same sequence of Bacillus subtilis. Maximum amylase production was observed, when B. subtilis cultured in medium containing starch at concentration 0.5%, and 10 g/L peptones as nitrogen source at pH 8.5 in when it was incubated for 48 h at 45°C. Conclusion: An amylase-producing bacterium were isolated from hot-spring water and was identified as B. subtilis. Amylase produced from B.subtilis had optimum temperature 45°C and pH 8.5 in shaking media.

“…The detergent amylase-producing bacteria are generally screened from soil [9,[18][19][20][21][22][23][24]. Some other bacteria are isolated from the marine sediment [25,26], watery environment [27,28], or fermented food [29] (Table 1).…”

“…The alkaline amylases and other detergent enzymes are now the key ingredients in the manufacture of detergents in the developed countries. Duramyl and PurafectOxAm are two detergent amylases manufactured by Novozyme and Genencore International, respectively, and available in the market [2,9]. The demand for detergent amylases with better properties is increasing every day since the current detergent amylases do not totally have all the desired characteristics.…”

Proteases, lipases, amylases, and cellulases are enzymes used in detergent formulation to improve the detergency. The amylases are specifically supplemented to the detergent to digest starchy stains. Most of the solid and liquid detergents that are currently manufactured contain alkaline enzymes. The advantages of using alkaline enzymes in the detergent formulation are that they aid in removing tough stains and the process is environmentally friendly since they reduce the use of toxic detergent ingredients. Amylases active at low temperature are preferred as the energy consumption gets reduced, and the whole process becomes cost-effective. Most microbial alkaline amylases are used as detergent ingredients. Various reviews report on the production, purification, characterization, and application of amylases in different industry sectors, but there is no specific review on bacterial or fungal alkaline amylases or detergent-compatible amylases. In this mini-review, an overview on the production and property studies of the detergent bacterial amylases is given, and the stability and compatibility of the alkaline bacterial amylases in the presence of the detergents and the detergent components are highlighted.
