“…The reduction in disease incidence and lesion diameter and the inducement of chitinase and β-l,3-glucanase by chitosan application were also recorded in pear fruits (Meng et al, 2010), tomato and grape (Muñoz et al, 2009), papaya (Ali et al, 2010), mango (Jitareerat et al, 2007). For citrus fruits, Fajardo et al (1998) reported that chitinase and β-l,3-glucanase were enhanced by separate application of chitosan and P. digitatum infection.…”

Effect of water-soluble chitosan (WSC) on green mould disease caused by Penicillium digitatum P4 was investigated in vitro and in vivo. Results of the experiments showed that P. digitatum P4 growth was much inhibited by WSC and inhibitory effect increased as WSC concentration increased. In vitro test results indicated that complete inhibition of spore germination and mycelial growth were observed in the medium containing 1 mg/ml WSC. In the in vivo study, WSC treatments significantly reduced disease incidence and lesion diameter of green mould disease on orange fruits. After 8 days of inoculation, the lesion diameter of orange fruits coated by 0.5%, 1%, 1.5% and 2% WSC were 5.49 cm, 5.01 cm, 3.22 cm and 1.87 cm, respectively, which smaller than that of control fruits. Biochemical experiments demonstrated that the activities of the main defense-related enzymes in flavedo tissue including chitinase and β-1,3-glucanase were enhanced by both P. digitatum P4 infection treatment and challenged with P. digitatum P4 and treated with WSC treatment. However, these enzymes of samples inoculated with P. digitatum only were lower than samples inoculated with P. digitatum P4 and treated with 2% WSC concentration. These findings suggest that the in vitro and in vivo effects of WSC on controlling green mould disease may be associated with direct antifungal activities and the elicitation of biochemical defense responses in fruit.

“…Although chitosan is a natural fungicide that has been used to inhibit fungal growth of several species such as Collectotrichum sp. (Muňoz et al 2009), this immobilising approach indicated that some fungal spores could tolerate the chitosan gelling condition because of their extra thick cell wall.…”

“…Among the various biosorption processes, fungal biosorption has been studied extensively because of the availability of filamentous fungi which are effective in the removal of heavy metals (Tsezos and Volosy 1982;Kapoor and Viraraghavan 1998;Preetha and Viruthagirl 2007;Bueno et al 2008). Chitosan, a natural substance derived from chitin, was used in this study as the supporting material for living biomass immobilisation even though its anti-microbial and fungicide activity have been reported (Muňoz et al 2009). The authors have previously reported the biosorption of nonylphenol, an endocrine disrupting compound onto the chitosan-immobilised and grown fungal beads produced by the resting spore form of R. arrhizus (Lang et al 2009).…”

Asexual spores of the filamentous fungus Rhizopus arrhizus were used as the resting biomass as they tolerate chitosan gelling for mycelia growing in chitosan beads. Biosorption of lead using the dead detergent pretreated chitosan-immobilised and grown fungal beads was performed with initial lead (II) nitrate concentrations ranging from 9.02 to 281.65 mg/L. The adsorption data were best correlated with equilibrium adsorption isotherms in the order Redlich-Peterson, Langmuir, Freundlich and Fritz-Schlünder by non-linear regression. The biosorption kinetic model of pseudo second-order (R 2 [ 0.99) fitted better than pseudo first-order and modified pseudo firstorder models. Among the four pseudo second-order kinetic models, the Blanchard model was the best fit for the experimental biosorption data. The rate-limiting step of biosorption of lead was shown to be intraparticle diffusion controlled according to Weber and Morris model fitting. The beads could be regenerated using 1 M nitric acid solution. This illustrated the good performance of the beads for regenerated sorption/desorption at least five cycles.

“…All stages of pomegranate tree development are susceptible to the disease. Latent infection may occur invisibly in healthy plants causing extensive crop losses due to anthracnose disease related symptoms (Munoz et al 2009). Primary and secondary sources of inoculum are from infected leaves and windborne conidia, respectively (Munhuweyi et al 2016).…”

During spring 2017, an anthracnose-like foliar disease was observed in the pomegranate orchards in the region. Disease incidence (%) ranged from 15 to 22. The objectives of this study were to characterise this fungal pathogen, based on morphology, molecular characteristics and pathogenicity. Foliar symptoms progressed light to dark brown, concentric, circular, distinct spots with yellowish halos. Also, salmon coloured spore masses were observed on pomegranate cv. Hicaz leaves in Kozan district. Cultural and morphological examinations and DNA sequence data revealed that the fungus associated with symptomatic leaves was Colletotrichum gloeosporioides. Pathogenicity testing was performed by inoculation of healthy leaves with a spore suspension of C. gloeosporioides. This confirmed C. gloeosporioides as causal agent of anthracnose symptoms on pomegranate in Turkey.
