development of resistant strains of pathogens to many fungicides as well as fungicide residues in food stuff have been resulted in attemps to develop biological agents as alternative methods to control post-harvest diseases. practical use of microorganisms requires formulated products that meet a number of criteria. in this study different carriers for powder formulation of p.guilliermondi were...

The effectiveness of curing oranges and lemons at 33 degrees C for 65h followed by storage under ambient and cold-storage conditions was investigated. This treatment effectively reduced the incidence of Penicillium digitatum (Pers) Sacc and P italicum Wehmer decay on inoculated and naturally infected oranges and lemons stored at 20 degrees C for 7 days. However, it failed to control green and b...

Fungicides are the most common agents used in postharvest treatment of fruit and are the most effective against blue mould, primarily caused by Penicillium expansum. Alternatively, blue mould can be treated with antagonistic microorganisms naturally occurring on fruit, such as the bacterium Gluconobacter oxydans. The aim of this study was to establish the antifungal potential of the G. oxydans ...

in this study, the effect of carbon and nitrogen sources, on production of yeast biomass was determined as well as the efficacy of various formulations of candida membranifaciens to decrease blue mold on apple. the media containing sugar cane molasses as carbon sources caused more yeast growth than the media supplemented with permeate powder. yeast extract as nitrogen source produced higher bio...

The application of the biocontrol agent Pantoea agglomerans EPS125 to unwounded fruits was practically ineffective for control of postharvest blue mould caused by Penicillium expansum when the treatment and subsequent wounding and pathogen inoculation were separated by periods of unfavourable conditions. This was due to a rapid decrease in viability of the alocthonous introduced biocontrol agen...

Classify the apple’s internal quality is important for apple’s quality. Mould core apple is not eatable and can reduce the juice quality if used for making juice. The core tissue’s color is brown and the density of mould core apple is lower than a normal apple. This paper describes the detection of apple’s one internal quality (mould core disease) on the physical basis -density. X-ray technolog...

BACKGROUND Antifungal prophylaxis is a promising strategy for reducing invasive fungal infections (IFIs) in allogeneic hematopoietic cell transplant (alloHCT) recipients, but the optimum prophylactic agent is unknown. We used mixed treatment comparison (MTC) meta-analysis to compare clinical trials examining the use of oral antifungals for prophylaxis in alloHCT recipients, with the goal of inf...

The internal quality of apple is impossible to be detected by eyes in the procedure of sorting, which could reduce the apple’s quality reaching market. This paper illustrates an instrument using X-ray and machine vision. The following steps were introduced to process the X-ray image in order to determine the mould core apple. Firstly, lifting wavelet transform was used to get a low frequency im...

At harvest, apple fruit are placed into wooden or plastic bins (approximately 400 kg of fruit per bin), which are then transported to storage and packing facilities. Prior to storage, fruit may be drenched with a fungicide to control postharvest diseases (10). Fruit are stored in the bins in either regular atmosphere (RA) or controlled atmosphere (CA) (1 to 2% O2 and 0.5% CO2) at –1 to 3°C (9)....
