From: Ant mediated redistribution of a xyloglucanase enzyme in fungus gardens of Acromyrmex echinatior
Xeg1 acitivity in fecal fluid is 4-5 times higher when ants eat fungus garden material. Xyloglucanase activities for fecal fluid produced by large workers of Acromyrmex echinatior provided with either a normal fungus garden diet or with sucrose water for 20 days. A Welch two sample t-test showed a significant reduction in xyloglucanase activity (t4.943 = 5.276, p < 0.01) when ants were deprived of fungus garden material. Enzyme activity levels are given as milliunits per fecal droplet (mean ± SE, n = 5 colonies)
