Studies made in the field of microbiological degradation of lignin have included investigations with sodium and calcium lignosulfonates. Kazanskii and Mikhailova (1936) were unable to grow several wood-rotting fungi on neutralized waste sulfite liquor, but found that infusorial earth mixed cultures could grow albeit slowly (in 50-60 days) if several alterations were made in the composition of t...

Titanium undergoes time-dependent degradation in biological capability, or "biological aging". It is unknown whether the biological aging of titanium occurs beyond four weeks and whether age-related changes are definitely associated with surface hydrophilicity. We therefore measured multiple biological parameters of bone marrow-derived osteoblasts cultured on newly prepared, one-month-old, thre...

Geochemical and biological processes that operate in the soil matrix and on the soil surface are important to the degradation of biosolids in soil. Due to the large surface area of soils it is assumed that the microbial ecology is associated with mineral soil surface area. The total mineral surface areas were determined for soils from eight different fields selected from a long term study (1972...

In this paper a kinetic study is made of the biodegradability of Aroclor 1242 in sandy soil employing a mixed culture of acclimatized bacteria. The assays were done in stirred tank reactors, and the biodegradation process was monitored by High Resolution Gas Chromatography (HRGC) with Electron Capture Detector. These results are supported by other indirect measurements and indicators of the exi...

Rapid industrialization has necessitated the manufacture and use of different chemicals in day to day life. Water is life but now-a-days due to advancement in industrialization, it a spoiling a lot. In the present study, an attempt was made to examine the isolation and identification of Bacillus species from marine soil, Nagapattinum seashore, Tamil Nadu, India. Dyes are collected from in aroun...
