Abstract: ABSTRACT Title: An Improved Biocoagulant Composition with a Natural Preservative to Inhibit 5 Microbial Growth in Bio-Coagulant. FIELD OF THE INVENTION The present invention relates to an improved bio-coagulant composition with a natural 10 preservative to inhibit microbial growth in bio-coagulant. This invention particularly relates to an improved bio-coagulant composition with a natural preservative and a process for the preparation of natural preservative using Azadirachta indica leaves, which is used to inhibit microbial growth in bio coagulants, extends shelf-life and maintains long term effectiveness. Bio-coagulants contain organic substances 15 vulnerable to microbial degradation, as environmental microbes consume and enzymatically decompose these substances, gradually reducing the effectiveness of bio-coagulant over time. Azadirachta indica leaves extract, used as a natural preservative, effectively inhibits microbial growth in bio-coagulants and helps maintain their effectiveness over time. 20 Fig. 1
