Microbial properties of pigmented bacteria isolated from bioenhancer ‘<em>Amrit pani</em>’

Abstract

<em>Amrit Pani</em> (Nectar water) contains consortia of beneficial microorganisms, out of which two pigmented bacteria, B₁ (yellow) and B₂ (orange) were isolated. Colonies of these microbes were smooth, 1-3 mm in diameter and identified as <em>Micrococcus luteus</em> (B₁) and<em> Micrococcus varians </em>(B₂). Both the bacteria were aerobic in nature, could be grown successfully on medium containing <em>p</em>H 7- 8 at 30 ^oC temperature. Isolated bacteria exhibited UV resistance and high pectinase activity 2.23 and 2.66 IU/mL, respectively. These bacteria have shown antimicrobial activity against <em>Colletotricum gloeosporioides </em>and <em>Fusarium solani </em>and extracted pigments shown DPPH activity (free radical scavenging activity) 86.11 and 59.02 %, respectively. Based on above study, <em>Amrit Pani</em> can successfully be used for the management of soil born diseases and fermentation of organic wastes.
