Influence of stationary and bioreactor cultivation on Lentinula edodes (Berk) pegler lignocellulolitic activity

This work aimed to study the stationary and periodically mixed culture of L. edodes to the production of lignocellulolitic enzymes activity. LE 95/17, LE 96/22 and Leax strains were incubated in 25 g of eucalyptus sawdust substrate in Erlenmeyer flasks in stationary culture at 25 degrees C and in a bioreactor with four complete rotations daily at 25 degrees C and 3% CO2. The samples were collected at 8, 11, 14, 17 and 20 days after the incubation. Oxidative and hydrolytic enzymes analyses were performed. Lignin peroxidase enzyme was not found in the lignolytic systernfor LE 95/17, LE 96/22 and Leax strains in the different incubation methods. The use of bioreactor could be a practicable system to induce the laccase activity for L22 and Leax and MnP activity for L17 and L22. The activity of the hydrolytic enzymes was higher in the stationary system in comparison to periodically mixed system in the bioreactor.

Space analysis of water erosion in the red-yellow latosol under conilon coffee cultivation

This work aimed to study the space behavior of the water erosion in a red-yellow latosol. Then a study was developed in an area with colinon coffee cultivation in an Experimental Farm of Bananal do Norte of INCAPER in Cachoeiro de Itapemirim - ES. Soil samples were obtained from 0,0 to 0,20 m depth in an irregular grid with 109 samples. The analyzed variables were granulometric fractions, erodibility (K), natural erosion potential (PNE), soil loss (A) and erosion risk (RE). All the variables showed space dependency with moderate index of space dependency and similar standard of space distribution. The soil loss is related with the space distribution of the granulometric fractions.

Effect of potassium fertilization in 'Rica' guava (Psidium guajava) cultivation

A field experiment was conducted from 1989-90 to 1991-92 to study the effect of potassium fertilization on guava (Psidium guajava L.). using 1-year-old plants of 'Rica', grown in a Kanhapludalf soil in the Jaboticabal region in Brazil. During the first year the K doses used were: 0, 24.9, 49.8, 99.6, 149.4 and 199.2 g K/plant, which were doubled during the second year and tripled during the third. In the third year the increase in g level showed positive response in yield. About 90% of the maximum yield observed was associated with 527 g K/plant and with a leaf content of 18.9 g K/kg.
