Structure of Bacterial Flagella | Microbiology

The structure of bacterial flagella have been described by Simon (1978), Doestsch and Sjoblad (1980) and Ferris and Beveridge (1985). A flagellum consists of three basic parts, the basal body, hook and filament (Fig. 4.3). (a) Basal body: M. L. De Pamphilis and J. Alder (1971) isolated the basal body of a flagellum of E. coli and B. subtilis and [...]

Classification of Algae | Microbiology

A famous botanist F.E. Fritsch (1935) classified algae into following 11 classes, based on pigmentation, reserve food material, flagellation and reproduction. Class 1. Chlorophyceae (= Isokontae): Generally algae are fresh water and chlorophyllous thallophytes. Chlorophyll b and carotenoides are present in chloroplasts. The cell wall is made up of cellulose and food is synthesized in the form of starch. Motile [...]

Classification of Actinomycetes | Microbiology

Actinomycetes are classified into 7 families. The classification is based on hyphal and reproductive structures. Family 1: Streptomycetaceae: Hyphae non-fragmented, aerial mycelium with chains of spores with 5 to 50 or more conidia per chain e.g. Streptomyces, Microdlobaspone and Sporictilhya. Family 2: Nocardiaceae: Hyphae typically fragmented e.g. Nocardia, Pseudonocardia. Family 3: Micromononsporaceae: Hyphae non-fragmented conidia borne singly or in pairs [...]
