Evaluation of plant growth promoting potential of four rhizobacterial species for indigenous system

Journal of Central South University 2013年第1期20卷 164-171页

作者： Mokone Peter Hou babalola olubukola oluranti Department of Biological Sciences Faculty of AgricultureScience and TechnologyNorth-West University

The aim of this work was to see whether Pseudomonas putida NWU12, Pseudomonas fluorescence NWU65, Vibrio fluvialis NWU37 and Ewingella americana NWU59 are beneficial to plants and are able to promote plant growth and development when inoculated as plant growth-promoting rhizobacteria (PGPR). The four rhizobacteria were tested in vitro for PGPR activities and on spinach and pepper in pot experiments. The inoculants are all positive for ammonia (NH3 ), catalase, hydrogen cyanide (HCN), phosphate solubilization and siderophore production. Among the inoculants, E. americana NWU59 is oxidase negative. P. putida NWU12 and P. fluorescence NWU65 are producing indole-3-acetic acid (IAA). The inoculants exhibit some PGPR activities and thus tested in the screen-house. Treatments are control (water) and the four inoculants. Rhizobacterial inoculants increase spinach (17.14%-21.43%) and pepper (15.0%-37.5%) plant heights over the control. Such inoculants have the potential of improving plant yield components and may be used as biofertilizer.

A Review of the Ubiquity of Ascomycetes Filamentous Fungi in Relation to Their Economic and Medical Importance

引用

Advances in Microbiology 2016年第14期6卷 1140-1158页

作者： Mary Augustina Egbuta Mulunda Mwanza olubukola oluranti babalola Department of Biological Sciences Faculty of Agriculture Science and Technology North-West University Mafikeng Campus Mmabatho South Africa Southern Cross Plant Science Southern Cross University Lismore Campus Lismore Australia Department of Animal Health Faculty of Agriculture Science and Technology North-West University Mafikeng Campus Mmabatho South Africa

Filamentous fungi are found in different habitats in the environment including, air, water and soil. This group of fungi contains organisms from different classes under the sub-phylum Pezizomycotina. They occur in mixtures such that you find many genera of filamentous fungi dominating a particular habitat or substrate. The wide distribution of filamentous fungi has resulted in it being used for different purposes. This review aims to analyse the different genera of fungi species referred to as filamentous fungi and their relevance economically and medically.
