Abstract
Amylases (E.C.3.2.1.1) are enzymes which catalyze the breakdown of -1,4 glycosidic linkages of starch to simple sugars and different monomeric products. Microbial amylases are essential enzymes compared with animals and plants amylases in industrial applications. Thus, in southern Nigeria, garri processing waste-water from mills poses a serious environmental challenge and this situation could be exploited by utilizing microorganisms colonizing the area to manufacture microbial products. This present study was aimed at evaluating the potential of fungi isolated from garri processing environment for amylase secretion and conduct a time course study of the enzyme production. Fungi were isolated from the soil and waste water from garri processing sites using Standard Microbiological Procedures. The five fungi isolated from garri processing environmental samples were screened using Lugols iodine. Three fungal isolates were then selected on the hydrolysis of starch in qualitative zonation agar plates but one isolate named B among them was better in starch hydrolysis related to highest clear zone plates. After qualitative screening, the three hyper production amylase extracted fungi were identified according to the morphological characteristics. The hyper producing amylase isolate B was then identified as Aspergillus flavus (RCBBR_AEAFUN2) and recorded as a novel strain in southern Nigeria according to molecular characteristics, which was selected for further studies. The current results of time course study showed that the maximum growth (2.453 g) occurred after 24 h of incubation at pH 4.5 while maximum enzyme production (2.3 U/ml/min) was obtained after 96 h of incubation at pH 3.5. Therefore, the hyper producing amylase from garri processing sites, Aspergillus flavus (RCBBR_AEAFUN2) novel strain has great prospects for future biotechnological and industrial applications and help in ameliorating the environmental pollution posed by the waste-water.
