Cow dung has a wide range of micro-organisms, like- endospore forming Bacillus, Enterococcus & protozoa. In the present investigation attempts were made to isolate bacteria using nutrient agar media (NAM). The isolated bacteria were identified on the basis of their colony characteristics, morphology, Gram’s staining and biochemical test. It was observed that spore forming bacillus were the predominant type of organism, which possibly helped in maturation of manure forming. | 2020 9 2 584-591 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 2 2020 Journal homepage http Original Research Article https Screening of Bacteria Present in Cow Dung Ayush Tomar Shalu Choudhary Lalit Kumar Megha Singh Nisha Dhillon and Sonam Arya College of Applied Education and Health Sciences Meerut India Corresponding author ABSTRACT Keywords Bacteria Cow dung Lactobacillus plantarum Cow dung has a wide range of micro-organisms like- endospore forming Bacillus Enterococcus protozoa.

Article Info Accepted 08 January 2020 Available Online 10 February 2020 Introduction Cow dung is excreted by bovine animal species which are herbivores. It consists of undigested residues of consumed matter which has passed through the cow s gastrointestinal system Teo Teoh 2011 . Cow dung is widely used in formation of manure which is used as bio-fertilizers. Manure of cow dung enhances the minerals of soil and also develops resistance power of plants against pests and plant diseases. It contains about 80 of water and has some part of undigested plants material that have high amount of organic substance. The microflora of cow dung contains a wide number of bacteria such as - Bacillus like lactobacillus as central endospore forming bacillus some cocci fungi and yeast such as Saccharomyces Sharma Singh 2015 . According to Ware et al. 1988 lower part of the gut of cow has probiotic acitivity due to presence of different types of microorganisms like Lactobacillus plantarum
