Gene characterization of Bradyrhizobium spp. strains contrasting in biological ...
Medeiros, Camila de; Pereira, Gilberto Aguiar; Freitas, Janyeli Dorini Silva de; Oliveira Filho, Olavo Bilac Quaresma de; Valle, Juliana Silveira doBacteria from genus Bradyrhizobium can establish symbiosis with soybean and supply the plant nitrogen demands via biological nitrogen fixation (BNF). This study aimed to characterize genes related to BNF efficiency in B. japonicum strains contrasting in BNF efficiency. These gene sequences were previously identified in B. japonicum (strain S370) as probably related to the BNF efficiency in soybean using a DNA s...

Oxidative enzymes activities from Lentinula edodes on agribusiness substrate
Regina, Magali; Broetto, Fernando; Colauto, Nelson Barros; Linde, Giani; Paccola-Meirelles, Luzia Doretto; Sermanni, Giovani GiovannozziBasidyomycete Lentinula edodes has its related enzymatic activity mainly on the agribusiness waste kind used as a substrate. The objective of this work was to verify the activity of oxidative enzymes lacase (Lac), lignina peroxidase (LiP) and manganese peroxidase (MnP) of three L. edodes strains, in stationary system, cultivated the 25 ºC, in the absence of light, in substrates wtih 20% of bran of rice, 1% of C...
Temperature and pH conditions for mycelial growth of Agaricus brasiliensis on a...
Colauto, Nelson Barros; Aizono, Patrícia Midori; Carvalho, Lis Ribeiro Magalhães de; Paccola-Meirelles, Luzia Doretto; Linde, Giani AndreaFew studies have been done to determine Agaricus brasiliensis Wasser et al. (A. blazei; A. subrufescens) basic mycelial growth characteristics on axenic cultivation. This study aimed to determine the optimal temperature and initial pH for mycelial growth of A. brasiliensis on malt extract agar medium to develop axenic cultivation techniques. Studied initial pH values for mycelial growth were adjusted to 3.0, 4....
The use of plant phatogenic Helminthosporium euphorbiae for the control of Euph...
Silva, Tânia Aparecida da; Yorinorí, José Tadashi; Paccola-Meirelles, Luzia DorettoThe genus Helminthosporium is known as an important pathogen of cereal crops such as barley, corn, rice and wheat. Several species of this genus are reported as toxin producers causing several types of leaf lesions, spots, discoloration or root and stem rots. The species H. euphorbiae (sin. Bipolaris euphorbiae) has been studied as a biological control agent for wild groundnut, Euphorbia heterophylla, a common ...
