β-Carotene from Yeasts Enhances Laccase Production of Pleurotus eryngii var. ferulae in Co-culture
Laccase is widely used in several industrial applications and co-culture is a common method for enhancing laccase production in submerged fermentation. In this study, the co-culture of four yeasts with Pleurotus eryngii var. ferulae was found to enhance laccase production. An analysis of sterilization temperatures and extraction conditions revealed that the stimulatory compound in yeasts was te...
متن کاملImprovement of yield of Pleurotus eryngii var. eryngii by substrate supplementation and use of a casing overlay.
Improved yield and biological efficiency (BE) of Pleurotus eryngii var. eryngii were achieved by supplementation of substrate with a commercial delayed-release nutrient and use of a casing overlay. Yield increases of 14% were achieved from cased substrates that were supplemented at time of casing with delayed-release nutrient (Remo's). Use of a casing layer enhanced yield by 141% over non-cased...
متن کاملGenetic Variability and Population Structure of the Mushroom Pleurotus eryngii var. tuoliensis
The genetic diversity of 123 wild strains of Pleurotus eryngii var. tuoliensis, which were collected from nine geographical locations in Yumin, Tuoli, and Qinghe counties in the Xinjiang Autonomous Region of China, was analysed using two molecular marker systems (inter-simple sequence repeat and start codon targeted). At the variety level, the percentage of polymorphic loci and Nei's gene diver...
متن کاملPleurotus eryngii species complex: sequence analysis and phylogeny based on partial EF1α and RPB2 genes.
The Pleurotus eryngii species complex comprises at least six varieties (var. eryngii (DC.: Fr) Quel., ferulae Lanzi, elaeoselini Venturella et al., nebrodensis (Inzenga) Sacc., tingitanus Lewinsohn et al. and tuoliensis C.J. Mou). This species is unique among the genus Pleurotus because in nature it is found in association with certain species of the Apiaceae (Umbelliferae) and Asteraceae (Comp...
متن کاملCollection of Group Characteristics of Pleurotus Eryngii Using Machine Vision
An information collection system which was used to group characteristics of pleurotus eryngii was introduced. The group characteristics of pleurotus eryngii were quantified using machine vision in order to inspect and control the pleurotus eryngii house environment by an automated system. Its main contents include the following: collection of pleurotus eryngii image; image processing and patter...
