Abstract Abstract Background Although the citric acid fermentation by Aspergillus niger is one of the most important industrial microbial processes and various aspects of the fermentation appear in a very large number of publications since the s, the effect of the spore inoculum level on fungal morphology is a rather neglected : Mattey Michael and Papagianni Maria.

This easy-to-use guide covers all body systems and fluids including a special chapter on acquisition and management of cytology specimens. Hundreds of vivid color images of normal tissue alongside abnormal tissue images .   Batch fermentations were carried out in a stirred tank bioreactor, which were inoculated directly with spores in concentrations ranging from 10 4 to 10 9 spores per ml. Morphological features, evaluated by digital image analysis, were classified using an artificial neural network (ANN), which considered four main object types: globular and elongated Cited by:

In the present study, pellet and dispersed mycelia morphology of Rhizopus arrhizus NRRL was analysed using image analysis software and the impact on fumaric acid production was evaluated. Batch experiments were carried out in shake flasks.

A semiautomatic image analysis protocol that was developed to characterize the mycelium morphology during the fermentation process based on four morphological types (unbranched, branched, entangled, and clumped microorganisms) was applied to study the effect of agitation on the morphology of T.

Image analysis is now a well established complement to optical microscopy, allowing routine quantification of microscopic observations. Recent method developments include location and enumeration of bacteria in solid foods, in situ microscopy and image analysis for on-line monitoring of yeast fermentations, Cited by: Application of image analysis to fungal fermentations.

Author: Cox, Philip William. ISNI: Awarding Body: University of Birmingham Current Institution: University of Birmingham Date of Award: Availability of Full Text. In order to better understand the relationship between viscosity changes and fungus morphology during fermentations of Trichoderma reesei, an accurate image analysis method has been developed to.

For Penicillium chrysogenum biomass from to 38 gL -L, volumes of cytoplasmic and vacuolised or degenerated regions can be converted successfully into dry weight estimations, even when Author: C.R.

Thomas, G.C. Paul, C.A. Kent, H.L. Packer, E. Keshavarz-moore, M.D. Lilly. Abstract. Fungal spores are used in the laboratory for culture maintenance and at laboratory and other scales as inocula for fermentations.

The spore swelling and germination processes constitute a major part of the lag phase, and the subsequent culture morphology and productivity can be greatly influenced by the initial concentration.

1 Review. The pace of progress in fermentation microbiology and biotechnology is fast and furious, with new applications being implemented that are resulting in a spectrum of new products, from renewable energy to solvents and pharmaceuticals.2/5(1). In most cases, the carbon source is the same compound used to provide energy.

Carbohydrates are generally preferred as carbon and energy sources; however, many yeasts can also grow on other organic compounds, including lower aliphatic alcohols, sugar alco- hols, organic acids, fatty acids, amino acids. The aim of this book is to cover the basics of image analysis from a statistical per-spective, and with emphasis on methods relevant to the biological sciences.

The book is written for both biological scientists and applied statisticians, whom, we assume, are mainly interested in analysing images of static objects in laboratory-type situations. An image-analysis scheme to detect fungal infections in digital fluorescence microscopy images is presented.

The scheme consists of the image preprocessing, segmentation, parameterization, and classification steps that all have a strong influence on the detection by: 2.

Digital image analysis is a powerful tool for getting relevant information in order to establish the mechanisms of mass transfer as well as to evaluate the viability of the mycelia.

A link between vacuolation and fragmentation of Penicillium chrysogenum mycelia in stirred tank submerged fermentations is reported. Quantitative information on vocuolation and morphology was obtained by image analysis.

In fed‐batch fermentations the coincidence of the events of rapid vacuolation and the fall of the mean total and main hyphal lengths suggests that hyphal.
