Growth patterns and light induced kinetics of the fungi <i>Cephalosporium sacchari </i>on agar plates

Abstract

Growth patterns and growth kinetics of the fungi <i>Cephalosporium sacchari</i> on agar surface have been investigated. The mycelium of fungi grows similar to non-living systems. The growth patterns have been developed on different culture media. The kinetic data obey the simple equation <i>d = mt +c</i> where <i>m</i> and <i>c </i>are slope and intercept respectively and t is the time. The growth was found to be light induced. Dependence of <i>p</i>H of media on morphology and growth of the microorganism has been studied. Two similar and dissimilar mycelia discs have been inoculated together at a fixed distance and the influence on patterns have been studied. The contact zone has been characterised by a lack of spores abbreviated as inhibition pattern. The suppressed sporulation at the contact zone is due to competition over nutrients.
