OVIEDO, Juan C; CASAS, Ana E; VALENCIA, Jaime A  and  GARCIA, Lucas. Evaluation of Three Variables of Growth of Pleurotus pulmonarius on Corncob Using Digital Image Processing. Inf. tecnol. [online]. 2016, vol.27, n.5, pp.27-36. ISSN 0718-0764.

Basidiomycete Pleurotus pulmonarius was cultivated on corncob in a Petri dish to evaluate its growth or vigor, analyzing the effect of humidity, pH and salt content in two levels, measuring its growth through polychromatic images processed using Matlab. One of the main drawbacks of solid-state fermentation is the difficult monitoring cell growth. The conventional methods of measurement are lengthy and costly procedures, reason by which alternatives must be seek for its measurement, being as possible tool that might be used is digital processing of images as done in this work. Statistical analysis was performed using Statgraphics Centurion XVI software. The analysis presented statistically significant difference for the moisture content and the presence or absence of salts. The maximum growth of Pleurotus pulmonarius was obtained with 80% moisture, pH=6 and presence of salts.

Keywords : digital image processing; Pleurotus pulmonarius; solid state fermentation; biomass.
