O cultivo da alface tem sido prejudicado por problemas fitossanitários, em especialmente o gênero Meloidogynes sp.. Na tentativa de minimizar prejuízos, busca-se práticas que sejam eficientes, baixo custo, e com reduzido impacto ambiental, tais como a utilização controle biológico. Objetivou-se avaliar potencial nematicida agentes biológicos infestação Meloidogyne para duas cultivares crespa. U...

BACKGROUND There is an imperative necessity for alternative sources of energy able to reduce the world dependence of fossil oil. One of the most successful options is ethanol obtained mainly from sugarcane and corn fermentation. The foremost residue from sugarcane industry is the bagasse, a rich lignocellulosic raw material uses for the production of ethanol second generation (2G). New cellulol...

Some 350 Trichoderma isolates were obtained from soil samples collected from different parts of Iran. Cultures were purified on 2% water agar by hyphal tip method prior to identification. Obtained isolates were identified using morphological features including colony characters (pigmentation and growth rate on PDA) and microscopic characters such as shape of conidiophores, shape and size of con...

The mangrove fungus Trichoderma atroviride was found to be tolerant the heavy metal cadmium and it is of high interest profile its metabolites gain insight into response toxicity. This study aimed investigate effect derivatization agents on number types present in cadmium-tolerant T. atroviride, detected using GC-MS analysis. intracellular extracellular treated with for ten days were derivatize...

Xylotrophic fungi are well known by their ability to excrete enzymes into environment. These have important biotechnological potential and some of them produce industrial enzymes. Besides, xylotrophic fungal species recently attracted a lot attention among researchers as source antibacterial drugs. Aim. To analyze the effect carbon in culture medium, conditions deep cultivation on mycelium yiel...

The antagonistic potential of seven species native Trichoderma against Rhizoctonia solani f.sp. sasakii were evaluated in dual culture method which includes T. asperellum (KU933476), koningiopsis (KU904460), Hypocrea lixii (KX0113223), harzianum (KU933471), ovalisporum (KU904456), (KU904458), atroviridae (KU933472). Among them showed highest inhibition percentage (78.09%), followed by (70.95%),...

Sequences of the internal transcribed spacer region 1 (ITS1) of the ribosomal DNA were used to determine the phylogenetic relationships of species of Trichoderma sect. Pachybasium. To this end, 85 strains-including all the available ex-type strains-were analyzed. Parsimony analysis demonstrated that the section is nonmonophyletic, distributing the 85 strains among three main groups that were su...
