Since in 1952, Société Francaise des Petroles B. P. published the fundamental study of the production of petroleum protein, many researches on the use of petroleum hydrocarbons as fermentation materials instead of carbohychate materials have been done. In this point, the distance between petroleum and microbes has become shorter and shorter, and there are many reviews about this aspect. However, it appears that the microbial activities in other various aspects of petroleum industries has generally been missed except the above-mentioned petroleum fermentation.
In this paper, some primary knowledge of microbiology is presented as an introduction to the readers who are not familiar with it, and then microbiological problems in petroleum industries are discussed, petroleum prospecting, petroleum secondary recovery, petroleum reservoir plugging, decomposition of drilling fluid additives, corrosion of metals, petroleum waste disposal, and, microbial contamination and deterioration of petroleum.
The author expects that this present paper helps the engineers and researchers in petroleum industries to have a microbiological viewpoint.

Low temperature oxidation of coal is influenced by various factors such as temperature, time, degree of oxidation, particle size, velocity of ventilation and so on.
This paper is concerned with the measurement of changed weight of coal caused by oxidation of low temperature using the weight method of thermobalance, and considers macroscopic mechanism of the formation and decomposition velocity of products due to sorption of oxygen.
On the other hand, the measurement is performed on the temperature rise by weight of produced gas and sorption of oxygen with the measuring apparatus of adiabatic type and an estimating method of calorific value in low temperature oxidation of coal is formulated.
For the elucidation of the decrease of calorific value and the temperature rise in the coal storage pile, distribution of wind pressure against the sloping surface and air resistance and its flow appearance in this pile are investigated. On the basis of this investigation, distribution of velocity of ventilation is estimated and after its application to the estimating method, the decrease of calorific value and the temperature rise are obtained and these are compared with the practical measurements.
