Rodrigues, André [UNESP]; Carletti, Carla D. [UNESP]; Bueno, Odair C. [UNESP]; Pagnocca, Fernando C. [UNESP]Made available in DSpace on 2022-04-28T20:40:05Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-01-01; The mandibular gland secretion (MGS) and the faecal fluid (FF) of the leaf-cutting ant Atta sexdens rubropilosa Forel affected the spore germination of selected microfungi isolated from nests of this insect. MGS was more effective than the FF, completely inhibiting the spore germination of four out of s...

Mendes, Thais D.; Rodrigues, André [UNESP]; Dayo-Owoyemi, Ifeloju [UNESP]; Marson, Fernando A.L. [UNESP]; Pagnocca, Fernando C. [UNESP]Made available in DSpace on 2022-04-29T07:11:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2012-12-01; The possible roles played by yeasts in attine ant nests are mostly unknown. Here we present our investigations on the plant polysaccharide degradation profile of 82 yeasts isolated from fungus gardens of Atta and Acromyrmex species to demonstrate that yeasts found in ant nests may play the role of makin...

No. of bitstreams: 0 Previous issue date: 2010-12-01; We profiled the microfungi associated with colonies of the urban ant Paratrechina longicornis Latreille in peridomicilar areas at Campinas, Brazil. A total of 137 microfungal isolates were obtained from ant carcasses and the most frequent taxa found were Aspergillus flavus (30.7%), Penicillium sp. (23.4...

Fernandes, Érika S. [UNESP]; Bueno, Danilo [UNESP]; Pagnocca, Fernando C. [UNESP]; Brienzo, Michel [UNESP]Made available in DSpace on 2020-12-12T02:14:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-07-07; Sugarcane bagasse is a recalcitrance lignocellulosic material with difficult to structure disorganize and it has low cellulose accessibility, negatively influencing the enzymatic saccharification. This study identified the minor particle size that resulted in the efficient diluted acid pretreatment (10 ...
In vitro study of volatile organic compounds produced by the mutualistic fungus...
Masiulionis, Virginia E. [UNESP]; Pagnocca, Fernando C. [UNESP]Made available in DSpace on 2020-12-12T02:23:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; Occasionally, the symbiosis of the fungus-growing ants is threatened by ascomycetous fungi mainly by species in the genus Escovopsis. GC-MS analyses were conducted to investigate the volatile organic compounds (VOCs) produced by Escovopsis and the mutualistic Leucocoprinus gongylophorus during dual-cult...

Pereira, Jaqueline S. [UNESP]; Costa, Rafael R. [UNESP]; Nagamoto, Nilson S. [UNESP]; Forti, Luiz C. [UNESP]; Pagnocca, Fernando C. [UNESP]Made available in DSpace on 2018-12-11T17:02:30Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-06-01; Fungus gardens of leaf-cutting ants harbor diverse alien fungi in addition to their fungal cultivar. Previous work suggested that alien microorganisms are likely derived from the substrata foraged by ant workers and incorporated into the fungus gardens. To test this hypothesis, we sampled 1014 garden fr...
