Fungi were isolated from the soil samples and screened by growing on Czapek Dox Agar medium supplemented with pasteurized skimmed milk and zone of protein degradation was noted. A total 23 soil fungi were isolated, out of those 8 proteases producing fungi belonging to 4 different genera were screened out. Soil protein was extracted from the soil sample and protein quantification was done by Bicinchoninic Acid (BCA) Protein Assay. Aspergillus showed the highest protein degradation and after Penicillium. Followed by Cladosporium and Trichoderma showed protein degradation nearly at a low level. Keywords: Soil Fungi, Proteinaceous Waste, Proteases, Bioremediation. INTRODUCTION protein of wastes in to simple amino acids. Waste can be defined as- waste is everything Proteinaceous waste are produced from that no longer has a use or purpose and different sources, including temple waste, requirements to be disposed of people generate plant by-products, dairy waste, as well as a lot of wastes by their daily activities and blood, hides, skin, and visceral proteins after these wastes adversely affect the human and removal from animals (Adhikari et al., 2018). environmental health (Yadav et al., 2015; Rao Places of historical, religious and touristic et al., 2010). Along with different types of significance around the world are often prone wastes, proteinaceous wastes are key to a great amount of waste leftovers by the pollutants of the environment. Proteins are one visitors. This is responsible for numerous of the most important and essential component environmental concerns but also serves as a for the sustainability of living thing. But when source of inoculums for several unwanted end of these proteins as a waste, it cause diseases or various other health problems environmental problems.

Wastes of this temple contain people offer several offerings to the deities, proteinaceous liquid waste along with solid which generally consist of coconuts, fruits, waste which is generally generated by worship flowers, leaves, clothes etc. out of which floral (Abhishek, Pooja etc.) in the temple. Five soil and coconut offerings are found in huge samples were collected in clean and sterile amount. People also offer some special types zipper polythene bags from the polluted soil of offerings to some kind of deities (Aruna et near the temple (Gaddeyya et al., 2012). al., 2016). There are many temples where Before collecting the soil sample top soil layer people do worship with only oil, milk, curd, was removed. The collected soil samples were rice, etc. The famous Mangalnath Temple is brought to the microbiology laboratory for the one of the well-known temples of India, which further study. is situated on the bank of Kshipra River in Screening of Proteolytic Fungi holy city Ujjain, Madhya Pradesh. It is For the screening and isolation of proteolytic believed that this temple is situated on the fungi from the soil sample, Czapek Dox Agar center point of the earth and the famous karka media was used. The soil dilution plate method line (Tropic of Cancer) also passes away from was performed to isolate fungi from the soil here. Here the pilgrims do worship of deity samples. From the collected soil samples 10g Mangalnath with rice and curd. Thousands of soil was diluted in 90ml of sterile distilled pilgrims come here every day and do worship. water and dilution prepared up to 10-6. 1ml of The number of pilgrims is very high on suspension was taken from each dilution of 10- Tuesday and special (worshiping) days than on 4, 10-5, and 10-6 and added to sterile petri plates other days. After the worship the mixture of (duplicate of each dilution) (Waksman, 1922). rice and curd is washed out which mixes Just before the pouring 5ml pasteurized directly in the soil which causes soil pollution. skimmed milk (as a protein source) and Unconventional technologies like Streptomycin antibiotic was added to the microbial waste treatment have become medium and mixed it well. After solidification progressively attractive in the light of their plates were incubated at 28oC ± 1 for 7 days. greater relative economical (Sharma, 2010; After incubation zone of proteolysis Gareth et al., 2003). Using the conventional surrounding the colony was observed on methods for pollutants degradation is generally medium. Production of proteases was expensive and cannot adopt for the long term. exhibited as clear zone due to hydrolysis of Bioremediation is a less energy-consuming protein around the fungal growth. Such type of and cost-effective alternative to the traditional fungi were screened and transferred on fresh methods (Seth et al., 2016). Inappropriate Czapek Dox Agar medium to obtain pure disposal or handling of waste results in culture. Pure culture was maintained and unsanitary conditions which further leads to stored at low temperature (Chandrasekaran et pollution in the environment. Although, the al., 2015; Seeley & VanDemark, 1981). management of wastes is considered as Characterization of Isolates essential part of better living habits (Singh et Isolates were identified on the basis of cultural al., 2017). The present study will reveal the and morphological characters with the help of importance of fungal proteases in manuals and literatures (Waksman, 1922; bioremediation of proteinaceous waste Rapper & Thom, 1949; Gilman, 2001; originated from temple and which fungi can do Alexopoulos, 2018). it more efficiently.
