Clay minerals are very common in nature and highly reactive minerals which are typical products of the weathering of the most abundant silicate minerals on the planet. Over recent decades there has been growing appreciation that the prime involvement of clay minerals in the geochemical cycling of elements and pedosphere genesis should take into account the biogeochemical activity of microorganisms. Microbial intimate interaction with clay minerals, that has taken place on Earth’s surface in a geological time-scale, represents a complex co-evolving system which is challenging to comprehend because of fragmented information and requires coordinated efforts from both clay scientists and microbiologists. This review covers some important aspects of the interactions of clay minerals with microorganisms at the different levels of complexity, starting from organic molecules, individual and aggregated microbial cells, fungal and bacterial symbioses with photosynthetic organisms, pedosphere, up to environmental and biotechnological implications. The review attempts to systematize our current general understanding of the processes of biogeochemical transformation of clay minerals by microorganisms. This paper also highlights some microbiological and biotechnological perspectives of the practical application of clay minerals–microbes interactions not only in microbial bioremediation and biodegradation of pollutants but also in areas related to agronomy and human and animal health.

“…Benih mentimun yang direndam suspensi A. vinelandii dapat meningkatkan kemampuan berkecambah dan pertumbuhan kecambah 16,4 dan 1,9%, serta panjang kecambah 11,8% dibandingkan kontrol yang hanya direndam dalam air. Reaksi peningkatan perkecambahan besarannya tidak sama antar jenis benih seperti tomat, kubis merah dan bit (Kurdish et al, 2008). ternyata tidak semua sama baik dalam menghasilkankan IAA serta hormon lain seperti GA3 yang berperan dalam mempengaruhi pembentukan akar cabang pada gandum.…”

Spinach required relatively high Nitrogen to grow it in less fertile fields. The use of free living N-fixing bacteria were expected to facilitate N supply to the crop. The research aims was to characterized of N-fixing bacterial isolates and its role to spinach germination. The exploration of bacterial isolates, were collected from wild spinach roots using LG and Ashby media. Bacterial isolates which were obtained, then being characterized based on its ability to dissolve P and produced indole compounds in Picovskaya and TSB media respectively, enriched with tryptophan. Superior isolates were used in the spinach germination test. Germination test using the UDK method in merang paper. The variables measured in this study were normal seedling, seedling vigor, root length, and height of normal seedling. The isolation results obtained 16 isolates that can fix N, 3 isolates (12BH3, 13BH4 and 1BH4) were higher in dissolving P and capable to produce indole compounds. Isolates 12BH3, 13BH3 and commercial isolates were used in the germination test. Test result showed that the bacteria can increase the N fixation, and high normal seedling sprouts.

“…Microbe preparations allow to regulate the composition and amount of microbe complex on the roots in accordance with the requirements and possibilities of plants. Multi‐sided activity of such associative microorganisms as Azotobacter and Bacillus is stressed in literature (Vaishlya et al , 2006; Kurdish et al , 2008; Melent'yev, 2007).…”

PurposeThe purpose of this paper is to study bio‐safe technology – impact of rhizospheric bacteria Azotobacter and Bacillus within the composition of environmentally clean complex microbiological biofertilizer “BioWais” prepared on the basis of nitrogen‐, phospho‐ and silicon‐bacterin on physiological parameters of plants: growth, productivity, the role of rhizobacteria in plants resistance to biotic and abiotic factors.Design/methodology/approachThe following contemporary methods of investigation of physiological parameters of biological objects: immunoenzyme analysis of phytohormones, method of combinatory light dissemination, determination of amino acid composition of grain proteins by ion‐exchange chromatography, spectrophotometric methods were used.FindingsThe positive impact of biofertilizer “BioWais” on plant growth and development, enhancement of resistance of bacterized plants to hypothermia and pathogenic infection, increase of carotid content were demonstrated.Research limitations/implicationsThe bacteria under study biopreparation were shown to act as plant growth‐promoting rhizobacteria foster increase of plant anti‐oxidant protection, adaptation of seedlings to hypothermia, synthesize cytokinins and indolyl acetic acid.Practical implicationsBacterial preparation increases quality and amount of agricultures yield, it may be recommended to treat seeds prior to planting with the view to stimulate germination, to enhance plants resistance to hypothermia and fungus‐induced diseases, for improvement of plant growth and development.Originality/valueNew, innovative, environmentally pure bacterial preparation BioWais showed significant efficiency for a number of agrocultures and may be used for acquisition of safe plant products of high quality (with high content of protein, essential amino acids and carotin, potential source of vitamin A, low content of nitrates).
