Analysis of genomic data suggests this activity to be linked with genes encoding glycoside hydrolases from family 3, 8 or 43. No endo-β-xylanase activity was detectable. Major end products were NVP-BGJ398 chemical structure lactate and acetate. A higher ratio of acetic acid to lactic acid was obtained during growth on XOS compared with growth on glucose. This is the first report on utilization of XOS in Weissella, indicating an increased probiotic potential for XOS-utilizing strains from the species pair W. confusa/W. cibaria, but also showing that XOS utilization is strain dependent for these species. “
“Millettia pinnata (Synonym Pongamia pinnata) is a viable source of oil for
the mushrooming biofuel industry, source for agroforestry, urban landscaping, and the bio-amelioration of degraded lands. It also helps in maintaining soil fertility through symbiotic nitrogen fixation. However, not much work is reported
on classification and characterization of the rhizobia associated with this plant. In the present study, an attempt was made to isolate rhizobial strains nodulating Millettia from soils collected from southern regions of India. The isolates were characterized using numerical taxonomy, 16S rRNA gene sequencing, and cross nodulation ability. The results showed high phenotypic and genetic diversity among learn more the rhizobia symbiotic with Millattia pinnata. The isolates formed five clusters at similarity level of 0.82 based on the results of numerical taxonomy. Results on 16S rRNA gene sequence analysis revealed that most microsymbionts of M. pinnata belonged to Rhizobium and Bradyrhizobium, which are closely related to Rhizobium sp., B. elkanii and B. yuanmingense. Among these isolates, some isolates could grow in a pH range of 4.0–10.0,
some could tolerate a high salt concentration (3% NaCl) and could grow at a maximum temperature between 35 and 45 °C. PtdIns(3,4)P2 M. pinnata formed nodules with diverse rhizobia in Indian soils. These results offered the first systematic information about the microsymbionts of M. pinnata grown in the soils from southern part of India. Millettia pinnata (L.) Pierre, an arboreal legume, is a member of the subfamily Papilionoideae. This medium-size multi-purpose tree is indigenous to the Indian sub-continent and south-east Asia and has been successfully introduced to humid tropical regions of the world as well as parts of Australia, New Zealand, China, and the United States. Historically, this plant has been used in India and neighboring regions as a source of traditional medicines, animal fodder, green manure, timber, poisoning the fish, and fuel. Millettia pinnata plays an important socioeconomic role in reforestation programs, urban landscaping and has recently been recognized as a viable source of oil for the burgeoning biofuel industry (Azam et al., 2005; Karmee & Chadha, 2005).
