![]() ![]() However, its slightly curved triseptate conidia are easily differentiated from those of D. oviparasitica, which are straight and 5-7 septate. also occurs on roots with this technique, and under the dissecting microscope, it may be confused with D. oviparasitica. If small quantities of soil are used instead of roots, D. oviparasitica is rarely observed. Under these conditions, D. oviparasitica is probably not nutritionally dependent on nematode eggs, but it apparently grows saprophytically on roots and on cornmeal agar. The fungus often sporulates prolifically on roots, and occasionally sporulates on agar. Conidia do not always occur on repeated samples from the same root system, but the reasons for this variability are not known. Organisms colonize roots and agar, predacious fungi begin to decline, and conidia of D. oviparasitica can often be seen protruding from roots ( Mankau, 1975). Also, the disappearance of hyphae in eggs following destruction of the embryo sometimes makes it difficult to identify the original parasite. This method gives a direct indication of the number of eggs invaded by D. oviparasitica, but it does not differentiate between parasitism of viable eggs and saprobic growth in dead eggs. Inoculated media are examined daily for D. oviparasitica. Clumps of parasitized eggs were washed in sterile water and added to cornmeal agar (cornmeal infusion, 50 g agar, 15 g water, 1 L), glucose-peptone agar (glucose, 10 g peptone, 10 g agar, 16 g water, 1 L), or YPSS agar (yeast extract, 4 g K2HPO4, 1 g MgSO4–7H20, 0.5 g soluble starch, 20 g agar, 16 g water, 1 L). Stirling and Mankau (1978a) collected the gelatinous matrix of Meloidogyne egg masses from host plants in the field and partially dissolved by treating in 1% NaOC1 for about 2 min, and eggs were examined for parasitic fungi. By combining the ITS sequence with morphologic characteristics, a new anamorphic species was described and illustrated together with its teleomorph. Conidia were elongated ellipsoids, 1–2 septate, mostly 1 septate. Conidiophores were either not branched or occasionally branched, bearing divergent sterigmata on the tip with a single conidium on each. (2009) isolated D. alba, a new species from the ascospores of Orbilia alba collected in Wenshan County, Yunnan Province, China. ![]() Therefore, it is described as a new anamorphic species, D. coccinella. Comparison of its morphologic and biologic characters and analysis of sequence data of the rDNA in ITS region suggest that the fungus is a separate species. Simple conidiophore that bears a single, cylindrical, 1-7- septate conidium with a round distal end, a monoblastic conidiogenous cell, cylindrical, and absence of nematode-trapping capability distinguish this anamorphic fungus from other Dactylella species. coccinella from the teleomorphic fungus Orbilia coccinella and described it as a new anamorphic species. ![]() Sterling and Mankau (1978) isolated D. oviparasitica from root knot nematode egg masses ( Meloidogyne spp.). Sunitha, in Beneficial Microbes in Agro-Ecology, 2020 3 Isolation of Dactylella Cold press processing retains the nutrients, purity, and freshness of taste found in a premium olive oil.T.R. This method is known to produce a greater yield, but at the expense of the quality of the oil’s health benefits. Many types of olive oil are processed by pressing olives at higher temperatures. We then bottle the oil directly from the cask.Ĭold pressing is a way to make olive oil without the use of heat or chemicals. To further avoid oxidization, we store the oil in a stainless steel cask under a layer of nitrogen. This preserves the health benefits of the oil. Within hours of their harvest, we cold press the olives in a closed-system that prevents the oil’s exposure to light and air. We handpick the olives to prevent bruising or damage during the harvesting process. The benefit, however, is that the fruit maintains higher levels of phenolic antioxidants and oleocanthal. By most standards, this is considered an early harvest, generally resulting in a lower yield. We harvest the olives used to make Oleavia Olive Oils in October. Throughout the Mediterranean, olives are traditionally harvested in November and December when olives are ripe and produce a higher yield. In addition to selecting a premium variety of olives, the process used to make Oleavia Olive Oils ensures maximum freshness, taste, and quality. ![]()
