Degradation of cellulose is of major interest in the quest for alternative sources of renewable energy, for its positive effects on environment and ecology, and for use in advanced biotechnological applications. Due to its microcrystalline organization, celluose is extremely difficult to degrade, although numerous microbes have evolved that produce the appropriate enzymes. The most efficient kn...
Four actinomycete strains, isolated from the overheated region of manure compost, were assigned to the genus Thermobifida on the basis of morphological, physiological and biochemical characteristics. All strains produced single, ovoid, heat-sensitive spores on dichotomically branched aerial hyphae. On the basis of chemotaxonomic traits, these isolates showed strong affinity towards members of t...
Cation Stimulation, Chlorella fusca, Green Alga, Multiphasic Uptake, Sulfate Analogues, Sulfate Starvation Sulfate uptake into the unicellular green alga Chlorella fusca Shihira et Krauss strain 211-8 b was described as a pH-, temperatureand energy-dependent process. Transport followed triphasic kinetics with /^-values of 1.3 x 10-5, 3.9 x 105 and 2.8 x 10 4 m . The Hill plot showed coeffi cie...
Reproductive cooperation confers benefits, but simultaneously creates conflicts among cooperators. Queens in multi-queen colonies of ants share a nest and its resources, but reproductive competition among queens often results in unequal reproduction. Two mutually non-exclusive factors may produce such inequality in reproduction: worker intervention or queen traits. Workers may intervene by favo...
Structure of a Thermobifida fusca lytic polysaccharide monooxygenase and mutagenesis of key residues
Background Auxiliary activity (AA) enzymes are produced by numerous bacterial and fungal species to assist in the degradation of biomass. These enzymes are abundant but have yet to be fully characterized. Here, we report the X-ray structure of Thermobifida fusca AA10A (TfAA10A), investigate mutational characterization of key surface residues near its active site, and explore the importance of t...
به منظور مطالعه تاکسونومی جنس آنامورفیک oidium در استان گیلان نمونه های مختلفی از نقاط مختلف این استان جمع آوری و به آزمایشگاه قارچ شناسی گروه گیاه پزشکی دانشکده کشاورزی دانشگاه گیلان منتقل شد. پس از تهیه اسلاید های میکروسکوپی، مشخصات ریخت شناسی مربوط به مرحله غیر جنسی نمونه ها توسط میکروسکوپ نوری بررسی شدند. برای تعیین ابعاد اندام های قارچی، 30 مورد از هر کدام آن ها در چند نمونه میکروسکوپی، تو...
Life-history trade-offs are influenced by variation in individual state, with individuals in better condition often completing life-history stages with greater success. Although resource accrual significantly impacts key life-history decisions such as the timing of reproduction, little is known about the underlying mechanisms driving resource accumulation. Baseline corticosterone (CORT, the pri...
