Abstract

The use of biocatalysts like enzymes in the development of environmentally sustainable processes has been reported as an ecofriendly approach for the current bioeconomy. This research aimed at producing and characterizing peroxidase from Aspergillus terrens isolated from water sample in Wukari, Taraba State, Nigeria. Fungi species from surface water sample obtained in Federal University Wukari, Taraba Nigeria were isolated through serial dilution of peptone water and was cultured in a room temperature in different petri dishes using Potato Dextrose Agar (PDA). A portion of the fungi growth chosen from the best growth of cultured water sample were cut and transferred into the 250 Erlenmeyer flask each containing an acceptable proportion of phosphate buffer, pH 6.0. The screening for peroxidase production was aseptically performed on a plate by inoculating the fermented medium with azur B dye. The appearance of a clear zone indicated a positive result for peroxidase activity. The incubation of the peroxidase enzyme was conducted over eleven days, with the highest enzyme yield observed on the eighth day. The results obtained in this study showed that the effect of pH on peroxidase activity was studied, revealing that the optimum pH for enzyme activity was 7.5. Peroxidase activity was lowest at pH 1. Temperature variation studies showed that the optimum temperature for peroxidase activity was 30°C. Peroxidase activity changed as substrate concentration was varied. Peroxidase activity was revealed to be highest at substrate concentration 1.9 mM. The kinetic parameters for peroxidase were investigated to be: Vmax = 10.57082; Km = 0.244186. The evidence presented in this research has shown that peroxidase can be produced in mass by using of white rot fungi from/around our surroundings and can be explored as a cheap source of peroxidase for industrial and biotechnological purposes. In conclusion, producing peroxidase from local isolates presents an eco-friendly and affordable alternative for industrial applications, contributing to environmental sustainability and public health.

Abstract

Edible mushrooms have been known to possess various phytochemical and micro nutrient levels. Edible mushrooms can be eaten and they supply nutritional benefits to the human body system. It is not widely consumed mainly due to paucity of information about it. Therefore, this research was conducted to compare the phytochemicals and micronutrients levels in two selected edible mushrooms (Pleurotus ostreatus and Agrocybe aegerita). Fully matured mushroom species of Oyster and Tea tree mushroom were collected, air dried and then stored in transparent polythene bags. Quantitative determination of phytochemicals and micronutrients (minerals and vitamins) present was carried out. Tea tree mushroom used in this research can be said to have the higher concentration of phytochemicals (phenols and poly-phenols), as there was no significant difference (p>0.05) in Oyster mushroom in comparison to Tea tree mushroom for phenols and poly-phenols. The results obtained from this research indicated that there was no significant decrease(p>0.05) in Oyster mushroom in comparison to Tea tree mushroom for Sodium, Iron, Magnesium, Selenium, Manganese. While there was a non-significant increase (p>0.05) in Oyster mushroom in comparison to Tea tree mushroom for Potassium, Calcium, Phosphorus, Copper. Tea tree mushroom had higher composition of vitamins A and C than oyster mushroom which were not significantly different (p>0.05). The findings in this study revealed that Tea tree mushroom (Agrocybe aegerita) is slightly better than Oyster mushroom (Pleurotus ostreatus) based on their phytochemicals and micronutrients (minerals and vitamins).
