## Abstract Experiments were conducted to study the effect of five different organic substrates viz. lactose, fructose, mannose, xylose and sodium acetate on the heterotrophic growth characteristics with emphasis on growth, pigment composition, heterocyst frequency and nitrogen fixation of __Anabae
## Abstract The effects of the pesticide hexachlorocyclohexane (HCH) on the nitrogen fixing blueβgreen algae __Anabaenopsis raciborskii__ and __Anabaena aphanizomenoides__ commonly found as blooms in fish ponds were studied. These algae were very sensitive to HCH, and a distinct decrease in growth

Twelve experiments are reported on naturally occurring groups of N,-fixing blue-green algae in which reduction of acetylene and 15N, were determined simultaneously. Simple averaging of the C,H.JN, reduction rates yielded a conversion factor of 4.4. Linear and log transform regression analyses yielde
