  • In 1961, Frenkel and Hirsch described strains of streptococci isolated from cases of bacterial endocarditis that grew only in the presence of other bacteria, around which they formed satellite colonies, or in media enriched with sulfhydryl compounds, such as cysteine. (thefreelibrary.com)
  • A 2-year (2010-2011) field experiment was conducted under hot arid environment at Bikaner, India to investigate the effects of exogenous sulphydryl (-SH) compounds (thioglycolic acid and thiourea) on the water relation, malondialdehyde (MDA) content, membrane stability, photosynthetic pigment contents, gas exchange parameters and antioxidant enzyme activities in moth bean ( Vigna aconitifolia L.) under water limiting environment. (springer.com)
  • Results suggest that under water limiting situation, exogenous -SH compound application improves photosynthesis, protects plants against oxidative damage by scavenging ROS and minimizing MDA content by elevated antioxidant enzyme activities. (springer.com)
