Electron microscope examination of sporangiospore sections from Rhizopus stolonifer (Ehrenb. ex Fr.) Lind. and R. arrhizus Fischer revealed details on intracellular organization not previously reported. Aldehyde fixation followed by chromeosmium postfixation permitted clear depiction of ribosomes hitherto unrevealed in these cells. Mitochondria were diversiform. Spore wall structures in the two...

Fungi associated with the pre and post-harvest fungal soft-rot diseases of ripe fruit of soursop (Annona muricata) and their effect on the nutrient composition of the fruit pulp were investigated. The fungal pathogens implicated in the soft-rot diseases of the fruit were Colletotrichium gloeosporoids, Rhizopus stolonifer and Aspergillus niger. There was a relative decrease in the carbohydrates,...

El fruto de yaca es afectado por diversos patógenos en la etapa postcosecha entre los que se encuentra el hongo Rhizopus stolonifer agente causal pudrición blanda. Para control este patógeno utilizan fungicidas dañan medio ambiente y afectan salud humana. Esta situación llevaa buscar alternativas seguras las quitosano, con características dela maduración frutos. Asimismo, sorbato potasio un com...

Electronic and electrical wastes (EEW) have increased exponentially in recent years due to technological progress. The uncontrolled incineration of these causes pollution air, soil, water that has dangerous effects on health human beings other living organisms. This work isolated fungi are capable degrading some electronic wastes. In this study, from soil polluted by EEW were grown potatoes dex...

This study aimed to assess microbial community diversity in recycled nutrient solutions used in soil-less glasshouse cultivation of tomato. One hundred bacterial strains, twenty oomycetes and 6 fungi were isolated and identified through genomic DNA isolation, PCR amplification of the ribosomal DNA region and database interrogations. Similarities of ITS regions with known species ranged from 95%...
