Bacteria were found that are capable of producing good yields of beta-amylase in unrefined media. The culture filtrates are free of alpha-amylase and isoamylase.

Label-free bacterial colony phenotyping technology called BARDOT (Bacterial Rapid Detection using Optical scattering Technology) provided successful classification of several different bacteria at the genus, species, and serovar level. Recent experiments with colonies of Bacillus species provided strikingly different characteristics of elastic light scatter (ELS) patterns, which were comprised ...

Fungal taxonomists routinely encounter problems when dealing with asexual fungal species due to poly- and paraphyletic generic phylogenies, and unclear species boundaries. These problems are aptly illustrated in the genus Phoma. This phytopathologically significant fungal genus is currently subdivided into nine sections which are mainly based on a single or just a few morphological characters. ...

pathogenicity of 4 isolates of erysiphe betae from 4 different geographical zones of iran on 5 genotypes of beet, with different levels of resistance to powdery mildew, was investigated. eight-week old plants were inoculated by conidia from 4 isolates separately. indices for infection were estimation of leaf infection and number of produced conidia on the leaf surface 3 weeks after inoculation....
