Abstract The mycelium materials incubating Pleurotus ostreatus fungi based on different substrate compositions were developed, the main components of which were poplar sawdust and cottonseed hull in different proportions. The hyphae on the surface of the samples become dense from appearance due to the addition of cottonseed hull. The Fourier Transforms Infrared analysis revealed that the cellulose, hemicellulose and lignin in substrates of all samples were degraded in different degrees owing to utilization by hyphae growth. The morphology and mechanical properties of the mycelial materials changed as the substrate compositions varied. The difference of properties among all mycelium materials was mainly attributed to the growth of mycelium and different substrate compositions. And the mycelium material (the ratio of poplar sawdust to cottonseed hull was 1) exhibited highest strength and lowest compression set, indicating that its size recovery capability was best. In comparison, the substrate of this material was more favorable to the growth of the mycelium and it showed optimal comprehensive performance among all samples. The mycelium material showed good potentiality for packaging application.

Selection Of

Laccase activity from Pleurotus ostreatus and Flammulina velutipes strains was investigated with various agro- and forestry residues by solid-state fermentation. Different species or strains belonging to the same species had the unique capacity of secreting laccase on solid-state fermentation with various agro- and forestry residues. Overall, the capacity of secreting laccase for P. ostreatus strains was superior to F. velutipes strains due to the value of maximum activity on various agro- and forestry residues, except on the stalk of straw. Compared with Populus beijingensis, corncob, and stalk of straw, the presence of cottonseed hull was helpful to improve laccase activity for P. ostreatus strains because the maximum laccase activity from cottonseed hull was higher than that from the other three agro- and forestry residues. The presence of stalk of straw was more helpful to improve laccase activity for F. velutipes strains because of the maximum laccase activity from stalk of straw was higher that from Populus beijingensis, corncob, and cottonseed hull. These results indicated the importance of selecting suitable agro- and forestry residues for fungi producing laccase. These findings contributed to the selection of suitable strains to obtain an integrated application of low-cost laccase in the factory.

Проанализированы данные литературы, характеризующие пищевые, лечебные и экологические свойства гриба Рleurotus ostreatus (вешенка обыкновенная). Вешенка – полноценный продукт питания, обеспечивающий потребность организма человека в белках, углеводах, жирах, витаминах и минеральных солях. В белках плодовых тел вешенки содержится 18 аминокислот, восемь из которых незаменимые (изолейцин, лейцин, лизин, метионин, фенилаланин, триптофан, треонин, валин). Лечебная ценность грибов характеризуется содержанием водорастворимых (тиамин В1, рибофлавин В2, ниацин В5, РР, пиридоксин В6, биотин В7, аскорбиновая и пантотеновая кислота) и жирорастворимых (кальциферол, эргостерол, токоферол) витаминов. Отмечена возможность значительного повышения эффективности использования отходов сельского хозяйства за счет получения плодовых тел, а также последующего применения субстрата после плодоношения в растениеводстве и животноводстве.
