Abstract. Jayus J, Akroman R, Nurhayati, Nugraha AS, Piluharto B, Seviour RJ. 2021. Structural elucidation of the exopolysaccharide produced by Curvularia lunata isolate RJ01. Biodiversitas 22: 2699-2705. An (EPS) was recovered from culture filtrates fungus RJ01 prepared in Jember, Indonesia. Based on a prominent peak at 883 cm-1, FTIR analysis suggested it is ?-D-glucan, proposal confirmed sub...

Context Barley can be included in poultry diets as a cost-effective energy-contributing ingredient. However, its inclusion meat chicken is limited because it considered viscous grain due to high crude fibre and soluble non-starch polysaccharide contents. Aims The study quantified the optimum rate of barley during different growing phases, using an incremental program. Methods Eight dietary trea...

Steroidal plant growth promoters (SPGP) have been continuously studied due to their high activity increasing biomass and resistance diverse stress factors. In our hands, a new SPGP family of 22-oxocholestanic compounds stands out at comparative level brassinosteroids (BSs). The potential against phytopathogens was through in silico molecular docking, these assays were performed with relevant en...

Different conditions of culture medium, incubation time, concentration and surfactant were tested to determine xyloglucanase activity. Trichoderma viride, Paecilomyces farinosus, Wardomyces inflatus and Pleurotus ostreatus showed increased xyloglucanase activities when the fungi grown on microcrystalline cellulose as the sole carbon source. Endoxyloglucanase activity increased with the growth o...

The purpose of this note is to give a necessary and sufficient condition for a semicharacter on a subsemigroup of a commutative semigroup G to be extendable to a semicharacter on G. A bounded complex function x on a semigroup G is called a semicharacter of G if x(x)9^0 for some xEG and x(xy) = x(%)x(y) ior all x, yEG. Semicharacters were introduced by Hewitt and Zuckerman [l] and in a slightly ...

Soybean (Glycine max) beta-1,3-endoglucanase (EC 3.2. 1.39) is involved in one of the earliest plant-pathogen interactions that may lead to active disease resistance by releasing elicitor-active carbohydrates from the cell walls of fungal pathogens. Ethylene induced beta-1,3-endoglucanase activity to 2- to 3-fold higher levels in cotyledons of soybean seedlings. A specific polyclonal antiserum ...

The mechanisms of incorporation of two antigens have been determined using a monoclonal antibody (3A10) raised against the material released from the mycelial cell wall by zymolyase digestion and retained on a concanavalin A column. One of the hybridomas secreted an IgG that reacted with two bands in Western blots. Indirect immunofluorescence showed that the antigens were located on the surface...

Laminarinase and endo-beta-1,4-glucanase were purified and characterised from the midgut gland of the herbivorous land crab Gecarcoidea natalis and the crayfish Cherax destructor. The laminarinase isolated from G. natalis was estimated to have a molecular mass of 41 kDa by SDS-PAGE and 71 kDa by gel filtration chromatography. A similar discrepancy was noted for C. destructor. Possible reasons f...

Chitinase, beta-1,3-glucanase, and protease activities were formed when Trichoderma harzianum mycelia, grown on glucose as the sole carbon source, were transferred to fresh medium containing cell walls of Botrytis cinerea. Chitobiohydrolase, endochitinase, and beta-1,3-glucanase activities were immunologically detected in culture supernatants by Western blotting (immunoblotting), and the first ...
