an identification of optimal environmental conditions and effective factors for growth and sporulation of biological control agents is indispensable for their mass production. in this study, the effect of some liquid and solid media were evaluted for beauveria bassiana sporulation. the results of experiments on b. bassiana indicated that in liquid media the effect of light (p=0.0001), food qual...

In vitro propagation of plant has played a very important role in rapidmultiplication of cultivars with desirable traits and production of healthy and disease-free plants. In the present investigation, the objectives were to optimize the micropropagation of Rose hybrid ‘Black Baccarat’ cultivar. In proliferation step, the nodal segments (1.5 cm) was cultured on both liquid and solid media (MS, ...

This study was conducted to evaluate the degradation of aromatic dyes and the production of ligninolytic enzymes by 10 white rot fungi. The results of this study revealed that Pycnoporus cinnabarinus, Pleurotus pulmonarius, Ganoderma lucidum, Trametes suaveolens, Stereum ostrea and Fomes fomentarius have the ability to efficiently degrade congo red on solid media. However, malachite green inhib...

High pressure behaviour of Na-hectorite in water media shows surprisingly strong similarities to graphite oxide compression in liquid media considering rather different chemical composition and structure of these two types of materials. Crystalline swelling with pressure induced insertion of additional solvent layer (not correlated with pressure point of liquid media solidification) was observe...

Micro size craters were created by interaction of nanosecond laser beam with titanium target in liquid media. The dimension of crater i.e. depth and width is important in some applications such as micromachining. When the interaction occurs in liquid environment, the ablated materials from the target expand into the liquid. The ablated material can affect the interaction process if the ablated ...

OBJECTIVES Determine the ability of the Cobas 4800 assay to detect high-risk human papillomavirus (HrHPV) and high-grade cervical lesions when using cervico-vaginal samples applied to liquid medium and solid media cards compared to a direct cervical sample. METHODS Two cervico-vaginal specimens (pseudo self-collected) were obtained from 319 women. One was applied to an iFTA Card (FTA) then th...

The Gen-Probe Group A Streptococcus Direct Test (GASDT), which detects the presence or absence of group A streptococci directly from pharyngeal specimens, utilizes a specific relative light unit (RLU) cutoff of 4,500 to differentiate between positive and negative test results. In response to a report by a manufacturer that the background RLU values for the Copan rayon swabs with liquid media we...

An efficient and cost effective protocol for in vitro propagation of Pineapple (Ananas comosus var. Queen) has been developed. In the proliferation stage, agar based Murashige and Skoog (MS) media was supplemented with 3.0 mg/l benzyleaminopurine (BAP), 0.5 mg/l indole acetic acid (IAA) and 50 mg/l adenine sulphate as RBC design experiment. Two approaches were taken to reduce the chemical cost ...
