Endophytic Actinomycetes as Potential Producers of Hemicellulases and Related Enzymes for Plant Biomass Degradation BABT
Robl,Diogo; Mergel,Carla Montanari; Costa,Patricia dos Santos; Pradella,José Geraldo da Cruz; Padilla,Gabriel.
Abstract Tailor made enzymatic preparation must be design to hydrolyze efficiently plant biomass, once that each plant biomass possesses a distinct cell wall composition. Most of actinomycetes used for plant cell wall degradation are focused on the cellulases and xylanases production. However, a wide range of enzymes must be produced for an efficient degradation of lignocellulose materials. During the last decade several unusual environments were studied to obtain strains that produce glycohydrolases with innovator characteristics. In this context, the present work concerned the selection of endophytic actinomycetes as producers of hemicellulases and related enzymes with different enzymatic profiles, for use in the deconstruction of lignocellulosic...

Occurrence of sulphate reducing bacteria (SRB) associated with biocorrosion on metallic surfaces in a hydroelectric power station in Ibirama (SC) - Brazil BABT
Marangoni,Paulo Roberto Dantas; Robl,Diogo; Berton,Marcos Antonio Coelho; Garcia,Carlos Mario; Bozza,Angela; Porsani,Mariana Vieira; Dalzoto,Patricia do Rocio; Vicente,Vânia Aparecida; Pimentel,Ida Chapaval.
The aim of this study was evaluate, two methods for the detection and identification of sulphate reducing bacteria (SRB): ML medium and PCR with specific primers for SRB groups. SRB were detected through the selective medium only on carbon steel, which showed corrosion. Employing specific PCR primer, SBR were detected from all the metallic components assayed, even those that did not present visible corrosion spots, such stainless steel and copper alloys. Despite the presence or absence of corrosion at the later stages effectively by using the selective medium,, the initial stages of the corrosion could only be detected by the amplification of total DNA with SRB specific primers. The early detection of SRB could be employed for preventing the damages on...

Spore production in Paecilomyces lilacinus (Thom.) samson strains on agro-industrial residues BJM
Robl,Diogo; Sung,Letizia B.; Novakovich,João Henrique; Marangoni,Paulo R. D.; Zawadneak,Maria Aparecida C.; Dalzoto,Patricia R.; Gabardo,Juarez; Pimentel,Ida Chapaval.
Paecilomyces lilacinus has potential for pests control. We aimed to analyze mycelial growth and spore production in P. lilacinus strains in several agro-industrial residues and commercial media. This study suggests alternative nutrient sources for fungi production and that the biotechnological potential of agro-industrial refuses could be employed in byproducts development.
