Resumo
O fungo Ganoderma lucidum (Fr.) Krast, também conhecido como Lingzhi ou Reish, é um basidiomiceto pertencente à família Ganodermataceae, muito estudado por suas características medicinais. Imunomodulação e atividade antitumoral são algumas de suas indicações mais importantes à saúde humana, devem-se principalmente à presença de polissacarídeos e triterpenóides, que há séculos são utilizados na China, Japão e Coréia por fins terapêuticos. Com a crescente demanda por pesquisa com uso de Ganoderma lucidum no tratamento de doenças, a otimização da produção comercial tornou-se necessária para atender as demandas de mercado e de pesquisa. Assim, os objetivos do presente trabalho foram: 1. avaliar e comparar a eficiência biológica e o rendimento de 7 linhagens de G. lucidum, 351, 1002, 0901, 0809, 339, 144, 202, cedidas por produtores e pesquisadores ao banco de linhagens do Módulo de Cogumelos FCA/UNESP. Todas cultivadas em substrato à base de serragem de eucalipto; 2. quantificar as concentrações de β-glucanas, fenólicos totais e proteínas nas linhagens estudadas. O substrato de cultivo foi composto de 80% de material volumoso (serragem de eucalipto) e 20% de farelos (trigo e soja) contendo 620g cada saco de cultivo. A quantificação das β-glucanas foi realizada por método enzimático; para a quantificação de fenólicos totais, utilizou-se o método de Folin-Ciocalteau e para proteínas totais o método utilizado foi de Lowry. O cultivo, desde a inoculação do substrato até a colheita dos basidiomas, durou, em média, 65 dias. Em relação a eficiência biológica as linhagens obedeceram a seguinte ordem 351 ≥ 1002...
The fungus Ganoderma lucidum (Fr.) Krast , also known as Lingzhi or Reish, is a basidiomycete belonging to Ganodermataceae family, widely studied for its medicinal characteristics . Immunomodulation and antitumor activity are some of his most important insights to human health, are mainly due to the presence of polysaccharides and triterpenoids , which are used for centuries in China, Japan and Korea for therapeutic purposes. With the growing demand for research use of Ganoderma lucidum in treating diseases , optimization of commercial production became necessary to meet market demands and research . The objectives of this study were: 1 . evaluate and 4 compare the biological efficiency and yield of 7 strains of Ganoderma lucidum , 351 , 1002, 0901 , 0809 , 339 , 144 , 202 , assigned by producers and researchers to bank lines Module Mushrooms FCA / UNESP . All grown on substrate with sawdust ; 2 . quantify the concentrations of β - glucan , total phenolics and proteins in the strains studied . The culture substrate was composed of 80 % of bulk material ( sawdust ) and 20% bran (wheat and soybeans ) containing 620g each bag cultivation . Quantification of β - glucans was performed by enzymatic method ; for quantification of total phenolic used the Folin -Ciocalteau total protein and the Lowry method was used . The cultivation , from inoculation to harvest the substrate of the mushroom lasted , on average, 65 days. Relative biological effectiveness strains obeyed the following order 351 ≥ 1002 ≥ 0901 = 0809 = 339 with 15.00% , 13.10 % , 11.77 % , 11.29 % and 10.87 % . The yield followed the same order of significance , and obtained the following values : 5.95, 4.98 , 4.31 , 4.29 , and 4.18 g kg - 1 strains respectively. The line with the highest concentration of β - glucans was 1002 with 10.50 g/100 g of dry mushroom. The strains with the highest concentration of total phenolics were 1002 and 08 ...
