Yeast diversity in four Malaysian spontaneous cocoa pulp fermentations.

<p>Box fermentation 1 (B1, October 2011), heap fermentation 1 (H1, October 2011), box fermentation 2 (B2, January 2012) and heap fermentation 2 (H2, January 2012). In total, 769 yeast isolates were identified, allowing an in-depth analysis of the yeast diversity. Yeast species are ordered according to the frequency by which they were isolated from the different fermentation samples. The upper eight species were found in at least three fermentations, while the other species were only found in two or less fermentations. When the yeast counts were above the detection limit, different colors represent the relative population size of a certain species at a certain time point (dark blue : <5%, light blue : 5–10%, dark yellow : 10–50%, yellow : 50–100%). Hollow squares indicate that the yeast species was detected when the yeast cell count had dropped below the detection limit.
