✦ Synopsis
Calothrix marchica LEMM. var. intermedia RAO has been found to grow abundantly in soil receiving the effluent of a molasses distillery. The effluent a t low concentrations (1-10%, v/v) and a t neutral p H increased the growth of the organism. The cyanobacterium grew photoheterotrophically as well as chemoheterotrophically in the medium supplemented with sucrose and lower concentration (lo%, v/v) of neutralized distillery effluent. The exogenous carbon sources were also utilized probably in certain specific biosynthetic process, for example, in the synthesis of sheath layer around the trichome of the cyanobacterium. Formation of sheath was not observed in the medium with mannose, pentoses and organic acids which did not support the heterotrophic growth.
