As a part of the research program designed to solve the nutritional problems of astronauts during extended explorations of space, the following experiments were conducted. Cell wall substances in the alga, Chlorella pyrenoidosa 71105 and the fungus, Linderina pennispora NRRL 2237 have been identified and localized by means of standard cytochemical techniques. Pectic material in the primary lamella and cellulose in the secondary lamella have been found in the wall of C. pyrenoidosa. The walls of the cells of L. pennispora are chitinous, with no indication of the presence of cellulose at any stage of development. The pectic material in the wall of the alga is in the form of a pectic-protein comples and the chitin in the walls of the fungal cells is in the form of a chitin-protein complex. The wall of C. pyrenoidosa reacts positively to an enzyme mixture of pectinase and cellulase and the walls of L. pennispora react similarly to chitinase. These identifications and reactions to enzymes can be used in the effort to bring about total assimilation of cell wall substances if these algal and fungal cells should be chosen as food materials in meeting the nutritional requirements of the space program.
Bacterial Physiology focuses on the physiology and chemistry of microorganisms and the value of bacterial physiology in the other fields of biology. The selection first underscores the chemistry and structure of bacterial cells, including the chemical composition of cells, direct and indirect methods of cytology, vegetative multiplication, spores of bacteria, and cell structure. The text then elaborates on inheritance, variation, and adaptation and growth of bacteria. The publication reviews the physical and chemical factors affecting growth and death. Topics include hydrogen ion concentration and osmotic pressure; surface and other forces determining the distribution of bacteria in their environment; dynamics of disinfection and bacteriostasis; bacterial resistance; and types of antibacterial agents. The text also ponders on the anaerobic dissimilation of carbohydrates, bacterial oxidations, and autotrophic assimilation of carbon dioxide. The selection is a dependable reference for readers interested in bacterial physiology.
This book aims to disseminate the most current research in applied microbiology presented at the III International Conference on Environmental, Industrial and Applied Microbiology (BioMicroWorld2009) held in Lisbon, Portugal, in December 2009.This volume offers an inviting exploration of microbiology from scientific and industrial research to consumer products in a compilation of more than 150 papers written by leading experts in the field, who afford critical insights into several topics, review current research and discuss future directions to stimulate further discussions. This book also serves as an update on the most important current microbial research, by providing a comprehensive overview of cutting-edge topics in a single volume, where readers can also gain insights into how microbiology can solve problems in everyday settings.Although largely intended for microbiologists interested in knowing the latest developments in agriculture, environmental, food, industrial, medical and pharmaceutical microbiology and microbial biotechnology, this book is also a great source of reference for scientists and researchers involved in advancements in applied microbiology.
Plants interact with a large number of microoganisms which have a major impact on their growth either by establishing mutually beneficial symbiotic relationships or by developing as pathogens at the expense of the plant with deleterious effects. These microorganisms differ greatly not only in their nature (viruses, phytoplasmas, bacteria, fungi, nematodes, ... ) but also in the way they contact, penetrate and invade their host. Histology and cytology have brought an essential contribution to our knowledge of these phenomena. They have told us for instance, how specialized structures of the pathogen are often involved in the adhesion and penetration into the plant, how the interface between both organisms is finely arranged at the cellular level, or what structural alterations affect the infected tissues. They have thus set the stage for the investigations of the underlying molecular mechanisms could be undertaken. Such investigations have been remarkably successful in the recent years, expanding considerably our understanding of plant-microorganism interactions in terms of biochemical changes, rapid modifications of enzymatic activities, coordinated gene activation, signal reception and transduction. Biochemistry, molecular biology and cellular physiology have taken precedence in the phytopathologist's set of methods.
